The function that models exponential growth is:
P(t) = P0*(1 + r)^t, where
P0 = P(0) is the initial value of P
r is the growth rate as a decimal
In our case we have:
P(0) = 2800
r = 0.035 or 3.5%
P(t) = 2800*(1 + 0.035)^t
P(t) = 2800*(1.035)^t
The same exponential function written using y and t is:
y = 2800*1.035^t.

X+ 4? idk I don't really understand the question...
Answer:
14 students
Step-by-step explanation:
Given
Let:
read a book
watched TV
So, we have:
-- total
Required
Students that did both (x)
This is calculated using:
So, we have:
This gives:
Open brackets
Collect like terms
<em>Hence, 14 students did both</em>
It’s 39 yards squared because the rectangle is 24+15 which is the triangle
