The number of books sold since 2005 at a book store can be modeled by the function N(t) = 5t + 36 and the price per
book can be modeled by P(t) = 0.5t2 – 3.2t + 8, where t
is the number of years since 2005.
According to this model, what is the total amount of revenue
generated by the store's book sales in the year 2011? Round
your answer to the nearest cent.

answerthe vertex form

step-by-step explanation:

my answer is$ 12

step-by-step explanation:

because 15 -2=12

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)
