7/5y= y+2/5y
0.68y = y-0.32y
3/5y=y-2/5y
1.32y=y+0.32y
The exponential function that models this situation is:

------------------------------------------
A decaying exponential function has the following format:

In which:
- y(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem:
- The stock started at $225, thus
. - Declines at a rate of 25% every 2 weeks, thus

The equation is:

<u>Given</u>:
Given that the measure of arc DF is 162°
We need to determine the measure of ∠E
<u>Measure of ∠E:</u>
The measure of ∠E can be determined using the inscribed angle theorem.
Thus, by inscribed angle theorem, we have;

Substituting
, we get;

Dividing, we get;

Thus, the measure of ∠E is 81°
5^8 / 5^12 = 5^(8-12) = 5^-4 = 1/5^4
