Question

CAN SOMEONE PLZ HELP?!?!?!

Answer 1

Answer:

B

Step-by-step explanation:

The exponential decay formula is

y= ab^x

where a is the initial value and

b = 1- decay rate

b= .9

.9 = 1 - decay rate

Subtract 1 from each side

.9-1 = 1-1-decay rate

-.1 = -decay rate

Multiply by -1

.1 = decay rate

Change to a percent

10 %  = decay rate

Answer 2

The answer is B.

In the parenthesis, we find the rate of increase or decrease of whatever is labeled, in this case, it is employees. In order to have an increase in rate, it must be a 1, or higher. In this problem it is lower, so the amount of employees are decreasing.

It is 10% decrease because 0.90 represents how many employees stay, while the rest away from 100 (10%) are decreasing in value, and we can figure that out by how many years and how many employees leave by plugging in a specific amount of years for t.

I really hope this helps. :)
