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.

In the diagram, the measures of angle 3 and angle 6 are 50 degrees. The measure of angle 5 is 130 degrees. Are lines c and d par
Virty [35]

Answer:

  (c)  Yes, because angle 3 and angle 6 are congruent

Step-by-step explanation:

Angles 3 and 6 are "alternate interior" angles. When those angles are congruent, as these are, then the lines crossed by the transversal are parallel.

__

We expect angles 5 and 6 to be supplementary because they are a linear pair. That fact says nothing about the relationship of line d to line c.
