Step-by-step explanation:

Step 1: Define

Identify

f(x) = -2x + 7

g(x) = x² - 2

Step 2: Find f(g(3))

Substitute in x [Function g(x)]: g(3) = 3² - 2Evaluate exponents: g(3) = 9 - 2Subtract: g(3) = 7Substitute in g(3) [Function f(x)]: f(g(3)) = -2(7) + 7Multiply: f(g(3)) = -14 + 7Add: f(g(3)) = -7

Answer from: Quest

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

= pi 5^2

= 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360 60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

Answer from: Quest

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
