What are the parts of the expressions?

A term in an expression are the parts of the expression that are connected together using addition or subtraction

A coefficient is the number multiplying a variable within a term of the expression

Therefore;

A. The expression 12•x + 13•y - 4•z + 2, can be written as follows;

12•x + 13•y - 4•z + 2 = 12•x + 13•y + (-4•z) + 2

The terms of the given expression 12•x + 13•y - 4•z + 2, which is the same as 12•x + 13•y + (-4•z) + 2, are therefore;

1. Terms; 12•x, 13•y, (-4•z), 2

The coefficients are;

2. Coefficients; 12, 13, -4, 2

B. The given expression is 9•a + 4•b - 18

In the figure below, angle B is a right angle, m∠BAC=30°, and the length of AC=12. If CD=5, find the length of AD.

Answers

The length of AD is option e √229.

Given,

ΔABD and C is a point between B and D. A and C makes a line and there forms another triangle, ΔABC.

∠B is a right angle = 90°

m ∠BAC = 30°

Length of AC = 12

Length of CD = 5

We have to find the length of AD.

First we can consider ΔABC.

Total interior angle of a triangle is 180°

We have given, ∠A as 30° and ∠B 90°.

Then ∠C = 180° - (∠A + ∠B) = 180 - (30 + 90) = 180 - 120 = 60

∠ACB = 60°

Trigonometric Function

Sin θ = (opposite side / hypotenuse)

We can find length of BC using trigonometric function.

In ΔABC,

For sin 30°, AC is the hypotenuse and BC is the opposite side.

So,

Sin 30° = (opposite side / hypotenuse)

Sin 30° = (BC/12)

BC = Sin 30° × 12

BC = 1/2 × 12

BC = 6

Now, we have to find the length of side AB.

For sin 60°, AB is the opposite side and AC is the hypotenuse.

So,

Sin 60° = (opposite side/hypotenuse)

Sin 60° = (AB/12)

AB = Sin 60° × 12

AB = √3/2 × 12

AB = 6√3

Now we can consider ΔABD.

In ΔABD, ∠B is 90°

Length of side AB = 6√3

Length of side BD = BC + CD = 6 + 5 = 11

Now, we can find the length of side AD using pythegorean theorem.

Hypotenuse = [tex]\sqrt{altitude^{2} +base^{2} }[/tex]

Here, AD is the hypotenuse, AB is the altitude and BD is the base.

So,

AD = [tex]\sqrt{AB^{2} +BD^{2} }[/tex]

AD = [tex]\sqrt{(6\sqrt{3} )^{2} +11^{2} }[/tex]

AD = [tex]\sqrt{36(3) + 121}[/tex]

AD = [tex]\sqrt{108+121}[/tex]

AD = √229

That is, the length of side AD is √229.

Answers

Train A's unit rate is 68 km per hour.

Train B's unit rate is 75 km per hour.

The faster train is Train B.

Which train is faster?

The unit rate of the trains is equal to the average speed of the trains. The unit rate is the total distance travelled by the train per time.

The unit rate can be determined by dividing the total distance travelled by the total time travelled. The train that is faster would have a higher unit rate per time.

Unit rate = total distance / total time

The unit rate for Train A is 68 kilometers per hour. This is because this is the total distance covered in 1 hour.

d = (68 x 1) = 68 km / hr

The unit rate for Train B = 150 / 2 = 75km / hr

Train B is faster because it covers more kilometers in one hour when compared with Train A.

The football team's total payroll is B. 2.5753 x [tex]10^{11}[/tex] dollars more than the baseball team's total payroll.

Option B is the correct answer.

We have,

To find how many more dollars the football team's total payroll is than the baseball team's total payroll, we need to subtract the baseball team's total payroll from the football team's total payroll.

Football team's total payroll = 2.6 x 10^11 dollars

Baseball team's total payroll = 2.47 x 10^9 dollars

Difference = Football team's total payroll - Baseball team's total payroll

Difference = [tex](2.6 \times 10^{11}) - (2.47 \times 10^9)[/tex]

To subtract these numbers, we need to make sure they have the same exponent:

2.47 x [tex]10^9[/tex] dollars = 0.247 x [tex]10^{10}[/tex] dollars

(move the decimal one place to the right)

Now, subtract:

Difference = (2.6 x  [tex]10^{11}[/tex]) - (0.247 x [tex]10^{10}[/tex])

Difference = 2.5753 x [tex]10^{11}[/tex] dollars

Select the system of linear inequalities whose solution is graphed.

Answer:

Third choice
x < -2; y ≤ -x -2

Step-by-step explanation:

The dotted vertical line passing through x = 2 shows it is a < inequality corresponding to x < -2. If it were a ≤ inequality, then it would be a solid vertical line

That eliminates the first two choices. Second choice is x < -3 which is not correct because we can see that the shaded region includes everything below x = -2 not below x = -3. For example, x = -2.5 is in the shaded region

So we have to choose between the third and fourth choices. Note that the line equation for choice 3 is y = -x -2 and for choice 4 it is y = -x +2


Choose (x, y) = (-3, 0)

choice 3
y ≤ -x -2
Substitute x with -3 in -x + 2 giving
-(-3) -2 = 3 - 2 = 1

Point(-3,1) lies on the line and therefore does satisfy the second inequality

choice 4
y ≤ -x + 2
Substitute x with -3 giving

-x + 2 = -(-3) + 2 = 3 + 2 =5
But (-3, 5) is not on the line. In fact, it is outside the shaded region so it does not satisfy the second inequality

So the correct choice is the third choice

is the ratio 63:90 equivalent to 9:15

Answers

Answer:

No

Step-by-step explanation:

Since ratios are simply proportions, they may be represented in multiple ways as long as the relationship remains equal.

Simplifying Ratios

There are 2 ways to check if these ratios are equivalent. The first is to simplify both ratios and see if they match each other. Firstly, find the greatest common factor (GCF) between the 2 numbers.

GCF of 63 and 90 = 9GCF of 9 and 15 = 3

Then, divide each ratio by its GCF

63:90 = 7:109:15 = 3:5

Since 7:10 is not equal to 3:5, we know that these ratios are not equal. It is important to note that this method only works when both ratios have been completely simplified.

Find the Relationship as a Decimal

Another to see if 2 ratios are equivalent is to see if their relationships are equal as decimals. To find the relationship of a ratio as a decimal, simply divide the 2 numbers within a ratio.

63 ÷ 90 = 0.79 ÷ 15 = 0.6

Clearly, the ratios do not have equal relationships. Thus, the ratios are also not equivalent.

Given that;

A quadratic equation is;

3x² = -12x - 15

Now, The equation is written as;

3x² + 12x + 15 = 0

Take 3 common, we get;

3 (x² + 4x + 5) = 0

x² + 4x + 5 = 0

Factorize the equation by using Sridharacharya Formula;

x = - 4 ± √4² - 4*1*5 / 2*1

x = -4 ± √16 - 20 / 2

x = - 4 ± √-4 / 2

Since, √-1 = i

x = -4 ± 2i / 2                            

x = - 2 ± i

It gives two values of x as;

Find an equation in standard form of the parabola passing through the points below.
(1,9), (2,4), (4, -30)
The equation of the parabola is y = ??

Answers

The equation of the parabola is : y = -6x² + 13x + 2

The general equation for parabola is -

y = ax² + bx + c. We will keep the values of x and y in this equation, to find the coefficients. Once we get the coefficients, again this equation will be used to find the equation of parabola based on given points.

For the point (1, 9)

9 = a(1)² + b(1) + c

9 = a + b + c : equation 1

For the point (2, 4)

4 = a(2)² + b(2) + c

4 = 4a + 2b + c : equation 2

For the point (4, -30)

-30 = a(4)² + b(4) + c

-30 = 16a + 4b + c : equation 3

Subtract equation 2 from equation 1

9 = a + b + c

-4 = 4a + 2b + c

We get: 5 = -3a -b

Rearranging the equation: 3a + b = -5 : equation 4

Subtraction equation 2 from equation 3

-30 = 16a + 4b + c

-4 = 4a + 2b + c

We get: -34 = 12a + 2b : equation 5

Multiplying equation with 2

6a + 2b = -10 : equation 6

Subtract equation 6 from equation 5

12a + 2b = -34

-6a + 2b = -10

6a = -24

a = -6

Keep value a in equation 6 to find the value of b

6(-6) + 2b = -10

-36 + 2b = -10

2b = 36 - 10

2b = 26

b = 13

Keep the value of a and b in equation 1 to find the value of c

-6 + 13 + c = 9

c = 9 - 7

c = 2

Keeping all the coefficients in general equation to find the equation of parabola -

y = -6x² + 13x + 2

Hence, the equation of parabola is : y = -6x² + 13x + 2

Find the inverse of f(x)=3x+1

Answers

The inverse of the given function f(x) = 3x + 1 is f⁻¹(x) = x/3 - 1/3.

What is the inverse of the given function function?

Given the function in the question;

f(x) = 3x + 1

To determine the inverse of the function, write f(x) as y.

f(x) = 3x + 1

y = 3x + 1

Now, interchange the variable

x = 3y + 1

Solve for y by subtracting 1 from both sides

x = 3y + 1

x - 1 = 3y + 1 - 1

x - 1 = 3y

Reorder

3y = x - 1

Divide both term in the equation by 3

3y/3 = x/3 - 1/3

y = x/3 - 1/3

f⁻¹(x) = x/3 - 1/3

Therefore the inverse of the given function f(x) = 3x + 1 is f⁻¹(x) = x/3 - 1/3.
