Assume the graph of a function of the form y = acos(k(x - b)) is given below. Which of the following are possible values for a, k, and b?

answer: the answer is ann

step-by-step explanation:

for volume, add base x height x width

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
