A cable television firm presently serves 8000 households and charges $50 per month. A marketing survey indicates that each decrease of $5 in the monthly charge will result in 1000 new customers. Let denote the total monthly revenue when the monthly charge is x dollars. Required:
a. Determine the revenue function R.
b. Sketch the graph of R and find the value of x that results in maximum monthly revenue.

answer: b

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
