The distance, in inches, from the starting position of a swinging pendulum over time, in seconds, is represented by the graph below. when f(x) = 0, the pendulum is at its starting position. when f(x) > 0, the pendulum is to the left of its starting position, and when f(x) < 0, the pendulum is to the right of its starting position. the function describing this graph is a transformation of the parent cosine function, y = cos x. which value best describes the amplitude of the transformed function? a. 0 inches b. 6 inches c. 1.5 inches d. 3 inches

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
