A store is open for business while it is being renovated. The noise from the renovation is increasingly driving away customers. The daily revenue, r (d), the store has made d days since renovation began is modeled by the function r (d) = 10,000 (0.939),
What is the factor of decay in this function?

Actually Welcome to the concept of Exponential function.

The factor of decay would be the one with a Index power that is variable in nature,hence

==> D. 0.939 is the correct answer

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

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).
