The picture shows a feeding trough that is shaped like a right prism. Surface A and B are identical trapezoids
(a) Label all the dimensions of one trapezoid face. What are the lengths of the 2 bases of the trapezoid? What is the height of each trapezoid face?

(b) Use the information from part b to answer, Surfaces A and B will be painted blue. What is the total area that will be painted blue? Show your work!

(c) The edges of the trapezoids need to be sanded. A piece of sandpaper advertises that it can send up to 20 cm. Will one piece of sandpaper be enough to sand all the edges of trough? Explain

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
