Question

PLEASE HELP ME PLEASE I BEG YOU

Answer 1

Answer:

I think it's B.

Step-by-step explanation:

Because the equation is 1 - 0.144/24 should represent the amount of emails to be answered after one day.

Answer 2

Answer:

D. The decay rate, which reveals the hourly rate of change in the number of customers whose subscriptions are due to be renewed.

Step-by-step explanation:

An exponential decay function is,

$f(x)=a(1-r)^x$

Where, a is initial value,

r is rate of change per period,

x is the number of periods,

(1-r) is decay factor that shows the periodic rate of change in the initial value.

Given expression that represents the number of such customers after n days is,

$15,000(1-\frac{0.144}{24})^{24n}$

By comparing,

15,000 is the initial number of customers who are due to be renewed,

$\frac{0.144}{24}$ is the change per hour in the number of customers,

24n is the total number of hours,

$(1-\frac{0.144}{24})$ is the decay factor or decay rate that reveals the hourly rate of change in the number of customers,

Hence, option 'D' is correct.
