Answer:

3x^3 -8*x^2 + 8*x + 3

Step-by-step explanation:

The standard form for a plolynomial is:

a*x^n + b*x^(n-1) + c*x^(n - 2) ........

We have:

(x-1)(3x^2-5x-3)

this is equal to:

3*x^3 - 5*x^2 + 3*x - 3*x^2 +5*x + 3

where the thing that i did is distribute the multiplication

this is equal to:

3x^3 -8*x^2 + 8*x + 3

The first 4 terms of the geometric sequence are 12 , 36 , 108 and 324.

In a geometric sequence, each term following the first is found by multiplying the preceding one by a constant, non-zero quantity known as the common ratio.

The nth term of a geometric series with first term a and common ratio r is given by [tex]a_n=ar^{n-1}[/tex] .

Given the first term of the geometric sequence is 12 .

And given [tex]a_n=a_{n-1}\times 3[/tex]

Now using the above formula:

a₂ = a₁ × 3

or, a₂ = 12 × 3 = 36

Again using the above formula:

a₃ = a₂ × 3

or, a₃ = 36×3 = 108

Similarly

a₄ = a₃ × 3

or, a₄ = 108 × 3 = 324

Hence the first four terms of the geometric sequence are 12 , 36 , 108 and 324 .

Answer:

[tex]f' \left(\dfrac{\pi}{3}\right) =\dfrac{1}{2}[/tex]

Step-by-step explanation:

Given function:

[tex]f(x)=\sin x[/tex]

The differentiation of sin(x) is cos(x).

[tex]\implies f'(x)=\cos x[/tex]

Therefore:

[tex]\implies f' \left(\dfrac{\pi}{3}\right) = \cos \left(\dfrac{\pi}{3}\right)[/tex]

[tex]\implies f' \left(\dfrac{\pi}{3}\right) =\dfrac{1}{2}[/tex]

ln (e) = 1, by the properties of logarithm.

Now,

As seen by the definition of logarithms, [tex]log_b(a)=x[/tex]

In case of natural logarithm, b = e, i.e., [tex]log_e(a)=x[/tex] = ln (a) = x

In the given expression, a = e

Hence, ln (e) = x

By properties of logarithms, we get that: ln (e) = 1.

Hence, ln (e) = 1, by the properties of logarithm.

The diameter of the given sphere is; 39.5 cm

The formula for Volume of Sphere is;

V = 4/3 πr³

where;

V is volume

r is radius

We are given; V = 32250 cm³

Thus;

4/3 πr³ = 32250

Make r the subject of the formula to get;

r = ∛((32250 * 3/4)/π)

r =  ∛7699.12

r = 19.75 cm

Step-by-step explanation:

(0,2) is the y-intercept

The value of the ratio is CD = 24 cm

The given parameters are

SR : CD = 3 : 4

SR = 18 cm

Substitute SR = 18 cm in the ratio SR : CD = 3 : 4

So, we have

18 cm : CD = 3 : 4

Express the ratio as a fraction

So, we have

18 cm/CD = 3/4

This gives

CD = 18 cm * 4/3

Evaluate

CD = 24 cm

The solution for the radical equation √(x+3) = 4√x-2 is 7 / 3.

The phrase "algebraic expression" refers to any arrangement of terms that have undergone operations like addition, subtraction, multiplication, division, etc. (or variable expression).. Let's use the equation 5x + 7 as an example. Thus, 5x + 7 is an illustration of an algebraic expression.

Eliminate the radical on the both sides by squaring on both sides- 

Both sides must be raised to the second power.

√(x+3) ²=(4√x-2 )²

After squaring we get

x+3=16(x-2)

Solving the equation-

We get rearranged equation as :

x+3=16x-32

15x=35 x=35/15 which further reduces to 7/3 .

Check if the  solution is correct by putting it in original equation-

putting x=7/3 in the equation √(x+3) = 4√x-2 

we get √16/3=√16/3

Therefore, the solution for the radical equation √(x+3) = 4√x-2 is 7 / 3.

The required value of sports imports of the United States in 2012 is $2,745,240,000,000.

.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

the total value of exports from the United States in 2012 = $2,210,585,000,000

Now it is also given that,

the total value of exports from the United States in 2012 = $837,965,000,000 more than half of the US imports

Therefore, we can write

the total value of exports from the United States in 2012 = $837,965,000,000 + imports/2

Putting the value of exports we get,

2,210,585,000,000 = 837,965,000,000 + imports/2

Taking alike terms together we get,

Imports/ 2 = 2,210,585,000,000 - 837,965,000,000

Solving we get,

Imports/ 2 = 1,372,620,000,000

Multiplying by 2 both the side by 2 we get,

Imports = 2,745,240,000,000

Thus, the value of imports of the United States in 2012 = $2,745,240,000,000

Thus, the required value of imports of the United States in 2012 is $2,745,240,000,000.

Based on the given function on the number of pears on the pear tree, the true statement is that The number of pears on the tree increases by 2 each week.

A linear regression line takes the form:

y = mx + b

y = number of pears

m = change in the number of pears per week

x = number of weeks

b = number of pears at first week

When the function is converted to a linear regression form, it takes the form:

P(x) = 2(2+x)

P(x) = 4 + 2x

This shows that the change in the number of pears per week is 2. This means that the number of pears on the tree increases by 2 each week

Since their dot product is zero, then (6,-3) and (2,4) are normal to each other.

Step-by-step explanation:

Two vectors are said to be normal or perpendicular to each other if the result of their dot product is equal to zero.

These two vectors are also called orthogonal to each other.

Let u = (u₁, u₂) and  v = (v₁, v₂), then the dot product u . v is defined as:

u . v = u₁v₁ + u₂v₂

To check whether the vectors are normal to each other, let us check their dot product.

The given vectors are: (6,-3) and (2,4).

Let u = (6, -3) and  v = (2, 4), then,

u . v = 6 . 2 + (-3) . 4

The value of x in the angles is 14.

When parallel lines are cut by a transversal, angle relationships are formed.

The angle relationships that are formed includes corresponding angles, alternate angles, vertical angle etc.

Therefore, the value of x can be found as follows;

m∠1 = m∠7 (vertical angles)

Therefore,

m∠7 = m∠15(corresponding angles)

Hence,

m∠1 = m∠15

m∠1 = 8x - 4

m∠15 = 6x + 24

Therefore,

8x - 4 = 6x + 24

8x - 6x = 24 + 4

2x = 28
