Aguest on a talk show tends to receive many phone calls right after she is on the show, and then the calls become less frequent. this can be represented by the equation y = 30(0.92)d, where y is the number of phone calls after d days. how many phone calls should she expect after a week?
a. 28
b. 23
c. 17
d. 2

C. 17

Step-by-step explanation:

Given: A guest on a talk show tends to receive many phone calls right after she is on the show, and then the calls become less frequent.

This can be represented by the equation , where y is the number of phone calls after d days.

Now, the number of days in a week = 7 days

Then, the number of phone calls she should expect after a week is given by :-

Hence, the number of phone calls she should expect after a week is 17.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
