Given the functions f(x) = 2x2 +5 and g(x) = 8+x find go f(-5)

A. 63
B.3.
C.2
D.23

Answers

Answer 1

Answer:

A. 63

Step-by-step explanation:

Given functions:

    f(x) = 2x² + 5

    g(x) = 8 + x

find:

g o f(-5)

Solution:

Start first by finding f(-5);

       f(x) = 2x² + 5

              = 2(-5)² + 5

              = 50 + 5

              = 55

Now

g o f(-5);

     g(55) = 8 + 55 = 63

Answers that are mixed numbers must be entered as an improper fraction or a decimal.

Answers

Answer:

x = -15/2 or -7.5

Step-by-step explanation:

6x - 4(x - 9) = 2(3 - x)

6x - 4x + 36 = 6 - 2x

2x + 36 = 6 - 2x

4x + 36 = 6

4x = -30

x = -30/4

x = -15/2

Check:

6(-7.5) + -4(-7.5 - 9) = 2(3 + 7.5)

-45 + 66 = 2(10.5)

21 = 21

Answer:

[tex]-\frac{15}{2}[/tex]

Step-by-step explanation:

6x-4(x-9)=2(3-x)

6x-4x+36=6-2x (expansion)

2x+36=6-2x (collecting like terms)

2x+2x=6-36

4x=-30 (-30/4)

The diameter of a cylinder is doubled, and the height is cut in half. what will happen to the volume of the cylinder? please!

Answers

Answer:

The volume will be four times the original volume.

Step-by-step explanation:

V = (pi)r2h is the formula for the volume of a cylinder. The formula becomes V = (pi)(2r)2h if the radius is doubled and the height remains the same. V = 4(pi)r2h after simplifying. ... Therefore the new volume would be 4 times the original volume.

Visitors to a cinematic are either children, adults or pensioners. Ratio of children to adult visitors is 1:2 Ratio of adults to pensioners is 3:4 A stratified sample of 85 is to be taken from the cinema visitors. How many pensioners should there be in the sample?

Answers

Ratio of children, adults and pensioners is 1 : 2 : 8/3 = 3 : 6 : 8.

Let, 3x is number of children.

So, 6x is number of adults and 8x is number of pensioners.

Now,

3x + 6x + 8x = 85

17x = 85

x = 5

Therefore, number of pensioners are 8×5 = 40.

Hence, this is the required solution.

Step-by-step explanation:

2(x - 5) = 4(x + 1)

Multiply the parenthesis by the outside numbers (simplify).

2x - 10 = 4x + 4

Combine like terms (add 20 to both sides, and subtract 2x).

0 = 2x + 14

Subtract 14 from both sides of the equation.

2x = - 14

Divide both sides of the equation by 2.

x = -7

The restaurant bill for Annette is $55.82.

She adds an 18% tip for the waiter.

What is the total cost of Annette's meal rounded to the nearest cent?

pls answer seriously, I'm failing this class its so hard for me :(

Answers

first we have to find 18% of $55.82, which we can do by using the equation 55.82 x 0.18

55.82 x 0.18 = 10.05

so the tip = $10.05

now we just add it to the original bill
55.82 + 10.05 = 65.87

so the total cost = $65.87

Which equation has a slope of 2 and a y-intercept of - 5?
X a. 2x + y = -5
b. 2x - y = 5
c.X + 2y = - 10
d. X - 2y = 10

Answers

Answer:

b. 2x - y = 5

you are able to change the equation to y = 2x -5. this is then in the form of y = mx + b.

m = slope and b = y-intercept

m = 2 and b = -5

Answer

d. x - 2y = 10

Step-by-step explanation:

The answer you chose does have the correct y intercept, but the incorrect slope, it was asking for a slope of 1/2, not a slope of -2.

REMEMBER: The y intercept is when x = 0, the x intercept is when y = 0.

To find the y intercept, substitute 0 for x, and solve for y. The slope is the coefficient of x when the coefficient of y is 1.

Just convert this standard form equation into slope intercept.

Standard Form: Ax + By = C.

Slope Intercept: y = mx + b. (m is the slope, b is the y intercept)

To convert just get y by itself completely on the left side of the equation. (y has to have a coefficient of positive 1)

x - 2y = 10

-x -x

-2y = -x + 10

÷2 ÷2 ÷2

-y = -1/2x + 5

×-1 ×-1 ×-1

y = 1/2x - 5 → y = mx + b

m = 1/2, and b = -5
