Ineed the answer asap a roofing contractor purchases a shingle delivery truck with a shingle elevator for $34,650. the vehicle requires an average expenditure of $7.50 per hour for fuel and maintenance, and the operator is paid $13.50 per hour.
(a) write a linear equation giving the total cost c of operating this equipment for t hours. (include the purchase cost of the equipment.) c(t) =
(b) assuming that customers are charged $42 per hour of machine use, write an equation for the revenue r derived from t hours of use. r(t) =
(c) use the formula for profit p = r − c to write an equation for the profit derived from t hours of use. p(t) =

60 for the first and 130 for the second

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.
