Answers

Answer 1

The value of M can be found by evaluating the definite integral of the given function over the given interval.

Start with the integral: [tex]∫[0, 12] (12x + 30)/(x^2 + 2x - 8) dx.[/tex]

Factor the denominator:[tex](x^2 + 2x - 8) = (x + 4)(x - 2).[/tex]

Rewrite the integral using partial fraction decomposition:[tex]∫[0, 12] [(A/(x + 4)) + (B/(x - 2))] dx[/tex], where A and B are constants to be determined.

Find the values of A and B by equating the numerators: [tex]12x + 30 = A(x - 2) + B(x + 4).[/tex]

Solve for A and B by substituting suitable values of [tex]x (such as x = -4 and x = 2)[/tex] to obtain a system of equations.

Once A and B are determined, integrate each term separately: [tex]∫[0, 12] (A/(x + 4)) dx + ∫[0, 12] (B/(x - 2)) dx.[/tex]

Evaluate the integrals using the antiderivatives of the respective terms.

The value of M will depend on the constants A and B obtained in step 5, which can be substituted into the final expression.

Derive the integral of the following: | 3x (3x + 3) sin 4x dx

Answers

We are asked to derive the integral of the function |3x(3x + 3)sin(4x) dx. The integral can be found by applying integration techniques such as substitution and integration by parts.

To integrate the given function, we can start by applying the product rule for integration, which states that ∫(uv) dx = u∫v dx + ∫u dv. In this case, we have u = |3x(3x + 3) and dv = sin(4x) dx.

Rearranging, we have dx = du/4. Substituting these values, we get ∫sin(4x) dx = ∫sin(u) (du/4) = (1/4)∫sin(u) du = (-1/4)cos(u) + C.

Next, we compute u∫v dx, which gives us |3x(3x + 3) * ((-1/4)cos(u) + C). Simplifying this expression, we have (-3/4)∫x(3x + 3)cos(4x) dx + C.

Finally, we need to find ∫u dv, which involves integrating x(3x + 3)cos(4x) dx. This can be done using the integration by parts technique, where we choose u = x and dv = (3x + 3)cos(4x) dx.

By applying integration by parts, we find that ∫x(3x + 3)cos(4x) dx = (1/4)x(3x + 3)sin(4x) - (1/4)∫(3x + 3)sin(4x) dx.

Substituting this result back into the original expression, we have (-3/4) [(1/4)x(3x + 3)sin(4x) - (1/4)∫(3x + 3)sin(4x) dx] + C.

Answers

The cost function, C(x), is obtained by integrating the marginal cost function, MC(x), which yields [tex]C(x) = Jx^2/2 t 4x + 2x + 4000[/tex], with J representing the indefinite integral operator and x representing the number of units produced.

The marginal cost of production is the cost of producing one additional unit of output. The cost function is the total cost of production, as a function of the number of units produced.

In this case, we are given that the marginal cost of production is given by the function MC(x) = Jxt 4 + 2. We are also given that the fixed costs are $4000.

The cost function is the integral of the marginal cost function. In this case, the cost function is given by the following equation:

C(x) = ∫ MC(x) dx = ∫(Jxt 4 + 2) dx

We can evaluate this integral as follows:

C(x) = Jx^2/2 t 4x + 2x + C

Answers

The term (0.95)^t represents the decay factor, where t is the number of years elapsed since the purchase. Each year, the value of the guitar decreases by 5% (or 0.95) of its previous value.

The function A(t) = 145(0.95)^t represents the value of Brandon's guitar t years after he purchased it in 2012. In this exponential decay model, the initial value of the guitar is $145, and the value decreases by 5% (0.95) each year.

The function A(t) calculates the current value of the guitar after t years, where A(t) is the value in dollars. Let's break down the equation to understand it further:

A(t) = 145(0.95)^t

The coefficient 145 represents the initial value of the guitar when t = 0, i.e., the value of the guitar at the time of purchase in 2012.

The term (0.95)^t represents the decay factor, where t is the number of years elapsed since the purchase. Each year, the value of the guitar decreases by 5% (or 0.95) of its previous value.

For example, if we want to find the value of the guitar after 5 years, we substitute t = 5 into the equation:

A(5) = 145(0.95)^5

By evaluating this expression, we can determine the current value of the guitar after 5 years.

f(x) = -x3+ 3x2 - 5 a) List the coordinates of any extrema (if they exist), and classify as a max or min. b) State where the function is increasing and/or decreasing, c) List any inflection points. d)

Answers

(a) This equation has two coordinates: x = 0 and x = 2, 0 at max and 2 at min. (b) function is increasing on these intervals. (c) x = 1 is an inflection point.

To find the extrema of the function, we need to find the critical points by taking the derivative and setting it equal to zero. Differentiating the function, we get f'(x) = -3x + 6x. Setting this equal to zero gives us -3x  + 6x = 0. Factoring out x, we have x(-3x + 6) = 0.

This equation has two solutions: x = 0 and x = 2.To determine whether these points are maxima or minima, we can evaluate the second derivative at these points. Taking the second derivative of f(x), we get f''(x) = -6x + 6. Substituting x = 0 and x = 2 into f''(x), we find that f''(0) = 6 and f''(2) = -6. Since f''(0) > 0, it is a minimum, and f''(2) < 0, it is a maximum.

(b) To find where the function is increasing or decreasing, we can examine the sign of the first derivative. Since f'(x) = -3x + 2 + 6x, we can test the intervals between the critical points x = 0 and x = 2. We find that f'(x) > 0 for x < 0 and 0 < x < 2, indicating that the function is increasing on these intervals. Similarly, f'(x) < 0 for 0 < x < 2 and x > 2, indicating that the function is decreasing on these intervals.

(c) To find the inflection points, we need to find where the concavity of the function changes. This occurs when the second derivative changes sign. From earlier, we know that f''(x) = -6x + 6. Setting f''(x) = 0, we find x = 1 as the potential inflection point.

To determine if it is an inflection point, we check the concavity on either side of x = 1. Plugging in values close to 1, we find that f''(0.5) = 3 and f''(1.5) = -3, indicating a change in concavity and confirming that x = 1 is an inflection point.

Find producer's surplus at the market equilibrium point if supply function is p = 0.2x +9 and the demand function is p = 173.4 2+11 Answer:

Answers

We need to determine the equilibrium price and quantity by setting the supply function equal to the demand function.

Given the supply function p = 0.2x + 9 and the demand function p = 173.4/2 + 11, we can set them equal to each other to find the equilibrium price:

0.2x + 9 = 173.4/2 + 11

Simplifying the equation, we have:

0.2x = 173.4/2 + 11 - 9

0.2x = 92.7

x = 92.7/0.2

x = 463.5

Substituting the value of x back into either the supply or demand function, we find the equilibrium price:

p = 0.2(463.5) + 9 = 93

The equilibrium price is $93, and the equilibrium quantity is 463.5 units.

To calculate the producer's surplus, we need to find the area between the supply curve and the equilibrium price line up to the equilibrium quantity. This area represents the additional revenue earned by producers above their minimum supply price. Since the supply function is linear, the producer's surplus is given by the formula:

Producer's Surplus = (1/2) * (Equilibrium Quantity) * (Equilibrium Price - Minimum Supply Price)

Using the equilibrium price of $93, the minimum supply price of $9, and the equilibrium quantity of 463.5 units, we can calculate the producer's surplus:

Producer's Surplus = (1/2) * 463.5 * (93 - 9) = 20238.75

Therefore, the producer's surplus at the market equilibrium point is $20,238.75.

Answers

The identity sin6x = 2 sin 3x cos 3x can be proven using the double-angle identity for sine and the product-to-sum identity for cosine.

The identity (cosx- sinx) = 1 - sin 2x can be derived by expanding and simplifying the expression on both sides of the equation.

The identity sin(x+x) = -sinx can be derived by applying the sum-to-product identity for sine.

To prove sin6x = 2 sin 3x cos 3x, we start by using the double-angle identity for sine: sin2θ = 2sinθcosθ. We substitute θ = 3x to get sin6x = 2 sin(3x) cos(3x), which is the desired result.

To prove (cosx- sinx) = 1 - sin 2x, we expand the expression on the left side: cosx - sinx = cosx - (1 - cos 2x) = cosx - 1 + cos 2x. Simplifying further, we have cosx - sinx = 1 - sin 2x, which verifies the identity.

To prove sin(x+x) = -sinx, we use the sum-to-product identity for sine: sin(A+B) = sinAcosB + cosAsinB. Setting A = x and B = x, we have sin(2x) = sinxcosx + cosxsinx, which simplifies to sin(2x) = 2sinxcosx. Rearranging the equation, we get -2sinxcosx = sin(2x), and since sin(2x) = -sinx, we have shown sin(x+x) = -sinx.

Answers

The double integral that would give the volume of the solid is: V = ∬ R (4 - x² - y²) dA

How to find the volume?

The volume of the solid bounded above by z = 4 - x² - y² and below by z = 0, using polar coordinates, is given by the expression: V = 2/3 a³ - (1/15) a⁵

a) Using rectangular coordinates, the double integral that would give the volume of the solid is:

V = ∬ R (4 - x² - y²) dA

where R is the region in the xy-plane that bounds the solid.

b) To convert to polar coordinates, we can express x and y in terms of r and θ:

x = r cos(θ)

y = r sin(θ)

The limits of integration for r and θ depend on the region R. Assuming the region R is a circle with radius a centered at the origin, we have:

0 ≤ r ≤ a

0 ≤ θ ≤ 2π

The volume in polar coordinates is then given by the double integral:

V = ∬ R (4 - r²) r dr dθ

where the limits of integration are as mentioned above.

Let's evaluate the volume of the solid using polar coordinates.

The double integral for the volume in polar coordinates is:

V = ∬ R (4 - r²) r dr dθ

where R is the region in the xy-plane that bounds the solid.

Assuming the region R is a circle with radius a centered at the origin, the limits of integration are:

0 ≤ r ≤ a

0 ≤ θ ≤ 2π

Now, let's evaluate the integral:

V = ∫₀²π ∫₀ʳ (4 - r²) r dr dθ

Integrating with respect to r:

V = ∫₀²π [2r² - (1/3)r⁴]₀ʳ dθ

V = ∫₀²π (2r² - (1/3)r⁴) dθ

Integrating with respect to θ:

V = [2/3 r³ - (1/15) r⁵]₀²π

V = (2/3 (a³) - (1/15) (a⁵)) - (2/3 (0³) - (1/15) (0⁵))

V = (2/3 a³ - (1/15) a⁵) - 0

V = 2/3 a³ - (1/15) a⁵

So, the volume of the solid bounded above by z = 4 - x² - y² and below by z = 0, using polar coordinates, is given by the expression:

                                          V = 2/3 a³ - (1/15) a⁵

Using integration by parts we obtained:

A(x) cosh(Bx) = x² sinh(2x)/2 - x sinh(2x) + cosh(2x)/2

Let's choose f(x) = x² and g'(x) = cosh(2x). Then, we can reconstruct the integral using the integration by parts formula:

∫[x² cosh(2x) dx] = x² ∫[cosh(2x) dx] - ∫[2x ∫[cosh(2x) dx] dx]

Simplifying, we have:

∫[x² cosh(2x) dx] = x² sinh(2x)/2 - ∫[2x * sinh(2x)/2 dx]

Now, we need to integrate the remaining term using integration by parts again. Let's choose f(x) = 2x and g'(x) = sinh(2x):

∫[2x * sinh(2x)/2 dx] = x sinh(2x) - ∫[sinh(2x) dx]

The integral of sinh(2x) can be obtained by integrating the hyperbolic sine function, which is straightforward:

∫[sinh(2x) dx] = cosh(2x)/2

Substituting this back into the previous equation, we have:

∫[2x * sinh(2x)/2 dx] = x sinh(2x) - cosh(2x)/2

Bringing everything together, the original integral becomes:

∫[x² cosh(2x) dx] = x² sinh(2x)/2 - (x sinh(2x) - cosh(2x)/2)

Simplifying further, we can write the clean and simplified result for the original integral as:

To find the difference quotient, we need to evaluate the expression (f(x+h) - f(x))/h for the given function f(x) = 2x² + 5x.

Let's substitute the values into the expression:

f(x+h) = 2(x+h)² + 5(x+h)

= 2(x² + 2hx + h²) + 5x + 5h

= 2x² + 4hx + 2h² + 5x + 5h

Now, let's calculate f(x+h) - f(x):

f(x+h) - f(x) = (2x² + 4hx + 2h² + 5x + 5h) - (2x² + 5x)

b. The vector equation of the line is r = (-1, 1, 0) + t(1, -1, -3), and the parametric equations are x = -1 + t, y = 1 - t, z = -3t.

How to find the equations of the plane and line?

a. To determine the Cartesian equation of the plane passing through points P(-1,0,0), Q(0,1,0), and R(0,0,-3), we can use the formula for a plane in Cartesian form.

The Cartesian equation of the plane can be found by using the cross product of two vectors formed by the given points P, Q, and R.

Taking the vectors PQ and PR, we find the cross product PQ × PR = (-1, 1, -1). This cross product provides the coefficients for the plane's equation, which is x - y - 3z = 0.

How to find the vector and parametric equations for the line?

b. The line passing through point P(-1,0,0) can be represented by a vector equation and parametric equations.

To obtain the vector equation of the line, we combine the position vector of point P with the direction vector of the line, which is the same as the cross product of the plane's normal vector and the vector PQ.

Thus, the vector equation is r = (-1, 1, 0) + t(1, -1, -3).

The parametric equations of the line can be obtained by separating the vector equation into three equations representing x, y, and z. These are x = -1 + t, y = 1 - t, and z = -3t.

Find the area of the surface generated when the given curve is revolved about the x-axis. y= 4x + 2 on (0,2] The area of the generated surface is square units. (Type an exact answer, using a as needed

Answers

The area of the surface generated when the curve y = 4x + 2 is revolved about the x-axis on the interval (0, 2] is 16πsqrt(17) square units.

To find the area of the surface generated when the curve y = 4x + 2 is revolved about the x-axis on the interval (0, 2], we can use the formula for the surface area of revolution.

The formula for the surface area of revolution is given by:

A = ∫[a,b] 2πy * ds

where [a, b] is the interval of the curve, y is the function representing the curve, ds is an element of arc length, and ∫ represents the integral.

To find the surface area, we need to express y in terms of x and find the expression for ds.

Given y = 4x + 2, we can express x in terms of y as:

x = (y - 2) / 4

To find the expression for ds, we can use the formula:

ds = sqrt(1 + (dy/dx)²) * dx

Let's calculate the necessary components and then integrate to find the surface area.

dy/dx = 4

ds = sqrt(1 + 4²) * dx

= sqrt(1 + 16) * dx

= sqrt(17) * dx

Now we can integrate to find the surface area:

A = ∫[0, 2] 2πy * ds

= ∫[0, 2] 2π(4x + 2) * sqrt(17) * dx

= 2πsqrt(17) * ∫[0, 2] (4x + 2) dx

= 2πsqrt(17) * [2x²/2 + 2x] evaluated from 0 to 2

= 2πsqrt(17) * (2(2)²/2 + 2(2) - 0)

= 2πsqrt(17) * (4 + 4)

= 16πsqrt(17)

Therefore, the area of the surface generated when the curve y = 4x + 2 is revolved about the x-axis on the interval (0, 2] is 16πsqrt(17) square units.

Find another way to solve this question.
Along a number line (0 -100) Fred and Frida race to see who makes it to 100 first. Fred jumps two numbers each time and Frida jumps four at a time. Investigate the starting point for Fred so that he is guaranteed to win?
I know you can solve it graphically by drawing two number lines and then counting how many jumps both Fred and Frida have.
And I know you can make a linear equation:
Eg. Fred= 2j + K
Frida= 4j
Then solve
(j meaning amount of jumps and K being starting position.)
Are there any other ways to solve it? If so explain the process and state the assumptions you made.

Answers

Yes, there is another way to solve the question without graphing or using a linear equation. We can analyze the problem mathematically by looking at the patterns of the jumps made by Fred and Frida.

Fred jumps two numbers each time, so his sequence of jumps can be represented by the equation: Fred = 2j + K, where j is the number of jumps and K is the starting position.

Frida jumps four numbers each time, so her sequence of jumps can be represented by the equation: Frida = 4j.

To guarantee that Fred wins the race, we need to find a starting position (K) for Fred where he will reach 100 before Frida does.

We can set up an inequality to represent this condition: 2j + K > 4j.

By simplifying the inequality, we get: K > 2j.

Since K represents the starting position, it needs to be greater than 2j for Fred to win. This means that Fred needs to start ahead of Frida by at least two numbers.

Therefore, the assumption we made is that if Fred starts at a position that is at least two numbers ahead of Frida's starting position, he is guaranteed to win the race.

By using this mathematical analysis and the assumption mentioned, we can determine the starting position for Fred that ensures his victory over Frida in the race to reach 100.

. Find the third Taylor polynomial for f(x) = sin(2x), expanded about c = = /6.

Answers

The third Taylor polynomial for f(x) = sin(2x), expanded about c = π/6 is:

f(x) ≈ √3/2 + (x - π/6) - (√3/6)(x - π/6)^2 - (2/3)(x - π/6)^3

For the third Taylor polynomial for f(x) = sin(2x), expanded about c = π/6, we can use the Taylor series expansion formula:

f(x) ≈ f(c) + f'(c)(x - c) + (1/2!)f''(c)(x - c)^2 + (1/3!)f'''(c)(x - c)^3

Let's find the values of f(c), f'(c), f''(c), and f'''(c) for c = π/6:

f(c) = sin(2(π/6)) = sin(π/3) = √3/2

f'(c) = 2cos(2(π/6)) = 2cos(π/3) = 1

f''(c) = -4sin(2(π/6)) = -4sin(π/3) = -2√3

f'''(c) = -8cos(2(π/6)) = -8cos(π/3) = -4

Now, let's substitute these values into the Taylor series expansion formula:

f(x) ≈ (√3/2) + (1)(x - π/6) + (1/2!)(-2√3)(x - π/6)^2 + (1/3!)(-4)(x - π/6)^3

Expanding and simplifying, we get:

f(x) ≈ √3/2 + (x - π/6) - (√3/6)(x - π/6)^2 - (2/3)(x - π/6)^3

This is the third Taylor polynomial for f(x) = sin(2x), expanded about c = π/6.

Find the general indefinite integral. (Use C for the constant of integration.) 11-06 t)(8 + t2) dt

Answers

The general indefinite integral of (11 - 6t)(8 + t^2) dt is (4t^4 - 6t^3 + 44t - 33ln|t| + C), where C is the constant of integration.

To solve this integral, we can distribute the terms inside the parentheses:

∫ (11 - 6t)(8 + t^2) dt = ∫ (88 + 11t^2 - 48t - 6t^3) dt

Next, we integrate each term separately. The integral of a constant multiplied by a function is simply the constant times the integral of the function, so we have:

∫ (88 + 11t^2 - 48t - 6t^3) dt = 88∫ dt + 11∫ t^2 dt - 48∫ t dt - 6∫ t^3 dt

The integral of dt is simply t, so we get:

= 88t + 11∫ t^2 dt - 48∫ t dt - 6∫ t^3 dt

To integrate each term involving t, we use the power rule of integration. The power rule states that the integral of t^n dt is (t^(n+1))/(n+1). Applying the power rule, we have:

= 88t + 11(t^3/3) - 48(t^2/2) - 6(t^4/4) + C

Simplifying further, we get:

= 88t + (11/3)t^3 - 24t^2 - (3/2)t^4 + C

Finally, we can rewrite the answer in descending order of powers of t:

= (4t^4 - 6t^3 - 24t^2 + 88t) - (3/2)t^4 + C

And this is the general indefinite integral of (11 - 6t)(8 + t^2) dt.

In general, the congruence ax ≡ b (mod m) will have gcd(a,m) solutions in Z/mZ. The given congruence will have gcd(4, 8) = 4 solutions in Z/8Z.

Given congruence is ax b (mod m).

We need to find the number of solutions of this congruence in Z/mZ.

Let us take an example to understand this. Let's take a congruence, 3x ≡ 4 (mod 7).

We need to find the solutions of this congruence in Z/7Z.

Since a and m are coprime here. Therefore, the congruence will have a unique solution in Z/mZ.

So, the given congruence will have a unique solution in Z/7Z.

Let's take another example, 4x ≡ 6 (mod 8).

We need to find the solutions of this congruence in Z/8Z.

Here, a = 4, b = 6, and m = 8.

We know that, for the congruence ax ≡ b (mod m) to have a solution in Z/mZ, gcd(a,m) must divide b.

Answers

The profit as a function of the number of items made, x, is given by the expression px - C(x), where p is the cost per item. To find the maximum profit, we need to determine the value of x that maximizes the profit function. Additionally, we can find the corresponding cost per item, p, that maximizes the profit. the maximum profit is achieved when x = 11.5, and the corresponding cost per item, p, is 13.5.

a) The profit as a function of x is given by the expression px - C(x). Substituting the given cost function C(x) = 15 + 2x and the relation p + x = 25, we have:

Profit(x) = px - C(x)

= (25 - x)x - (15 + 2x)

= 25x - x^2 - 15 - 2x

= -x^2 + 23x - 15

b) To find the value of x that maximizes the profit, we need to find the vertex of the quadratic function -x^2 + 23x - 15. The x-coordinate of the vertex is given by x = -b/(2a), where a = -1 and b = 23. Therefore, x = -23/(2*(-1)) = 11.5.

c) To find the corresponding cost per item, p, that maximizes the profit, we substitute the value of x = 11.5 into the relation p + x = 25. Therefore, p = 25 - 11.5 = 13.5.

Find the equation of the line with the given properties. Sketch the graph of the line. Passes through (-4,3) with a slope of 2. Type the general form of the equation of the line.

Answers

The graph of this line will be a straight line where slope is 2 passing through the point (-4,3) and it extends infinitely in both directions.

To find the equation of the line, we'll use the point-slope form of a linear equation: y - y₁ = m(x - x₁), where (x₁, y₁) is a point on the line, and m is the slope.

Given that the line passes through (-4,3) and has a slope of 2, we can substitute these values into the equation. Therefore, the equation becomes y - 3 = 2(x - (-4)).

This equation when simplified, we get y - 3 = 2(x + 4). Distributing the 2, we have y - 3 = 2x + 8.

Rearranging the equation to the general form, we get 2x - y = -11.

Find the length and width (in meters) of a rectangle that has the given area and a minimum perimeter. Area: 25 square meters.
a) 5 meters by 5 meters
b) 10 meters by 2.5 meters
c) 6.25 meters by 4 meters
d) 7.5 meters by 3.33 meters

Answers

The length and width of a rectangle with an area of 25 square meters and minimum perimeter is 5 meters by 5 meters.

In order to find the length and width of a rectangle with a given area and minimum perimeter, we need to use the formula for perimeter, which is P = 2L + 2W. We want to minimize the perimeter while still maintaining an area of 25 square meters, so we can use algebra to solve for one variable in terms of the other.
Starting with the formula for area, A = LW, we can solve for L in terms of W by dividing both sides by W: L = A/W. Then, we can substitute this expression for L into the formula for perimeter: P = 2(A/W) + 2W.


To see why this method works, we can think about what we're trying to accomplish. We want to minimize the perimeter of the rectangle while still maintaining a given area. Intuitively, this means we want to "spread out" the rectangle as much as possible while keeping the same amount of area. One way to do this is to make the rectangle as close to a square as possible, since a square has the most even distribution of length and width for a given area. In other words, if we have a fixed area of 25 square meters, the most efficient way to use that area is to make a square with side length 5 meters. To prove this mathematically, we can use the formula for perimeter and the formula for area to express one variable in terms of the other, and then use calculus to find the minimum value of the perimeter. This method gives us the same result as our intuitive approach of making the rectangle as close to a square as possible, and shows that this is indeed the most efficient use of the given area.

Answers

To find f'(1), the derivative of the function f(x) at x = 1, we can differentiate the given equation and substitute x = 1 and f(1) = 2 to solve for f'(1).

Let's differentiate the equation f(x) – x[f(x)] = -9x + 3 with respect to x using the product rule. The derivative of f(x) with respect to x is f'(x), and the derivative of -x[f(x)] with respect to x is -f(x) - xf'(x). Applying the product rule, we have:

f'(x) - xf'(x) - f(x) = -9

Rearranging the equation, we get:

f'(x) - xf'(x) = -9 + f(x)

Now, substituting x = 1 and f(1) = 2 into the equation, we have:

f'(1) - 1*f'(1) = -9 + 2

Simplifying the equation gives:

f'(1) - f'(1) = -7

Therefore, the equation simplifies to:

Answers

The given quantities are vectors v = 4i - 5j + 3k and w = -41 + 3 - 2k. By calculating 2v - 3w, we find the resulting vector to be i + Di. For the second part, if v = 4i - 3j + 4k and w = -31 + 3j - 4k, we calculate the quantity ||v - w|| and find that it is equal to 0.

First, let's calculate 2v - 3w using the given vectors v = 4i - 5j + 3k and w = -41 + 3 - 2k. Multiplying each vector by their respective scalar and subtracting, we get:

2v - 3w = 2(4i - 5j + 3k) - 3(-41 + 3 - 2k)

= 8i - 10j + 6k + 123 - 9 + 6k

= 8i - 10j + 12k + 114

Therefore, 2v - 3w simplifies to i + Di, where D = 12.

Moving on to the second part, given v = 4i - 3j + 4k and w = -31 + 3j - 4k, we need to calculate the quantity ||v - w||. Subtracting w from v, we have:

v - w = (4i - 3j + 4k) - (-31 + 3j - 4k)

= 4i - 3j + 4k + 31 - 3j + 4k

= 4i - 6j + 8k + 31

To find the magnitude, we use the formula ||v - w|| = √(a^2 + b^2 + c^2), where a, b, and c are the components of v - w. In this case, a = 4, b = -6, and c = 8. Therefore:

||v - w|| = √((4)^2 + (-6)^2 + (8)^2)

= √(16 + 36 + 64)

= √116

= 2√29

Hence, the quantity ||v - w|| simplifies to 2√29, and it is equal to 0.

The total weekly cost is given by C(x,y)=x2+(1/5)y2+46x+54y+800, where x is the number of units produced in Miami and y is the number of units produced in Baltimore. How many units should be produced in each plant to minimize the total weekly cost?
