Answer:
The function is defined as [tex]V = a (1 +r)^{t}[/tex] and Sasha investment of $1000 that earns 8% interest compounded annually becomes $1080 .
Step-step- Explanation:
As the function is defined by
[tex]V = a (1 +r)^{t}[/tex]
Where a is the initial value , t is time in years and r is the rate of interest in the decimal form .
As given
Sasha invests $1000 that earns 8% interest compounded annually.
a = $1000
8% is written in the decimal form .
[tex]= \frac{8}{100}[/tex]
= 0.08
t = 1 years
Putting all the values in the formula
[tex]V = 1000(1 +0.08)^{1}[/tex]
[tex]V = 1000(1.08)[/tex]
V = $1080
Therefore the function is defined as [tex]V = a (1 +r)^{t}[/tex] and Sasha investment of $1000 that earns 8% interest compounded annually becomes $1080 .
Answer:
[tex]V(t)+1000(1.08)^{t}[/tex]
Step-by-step explanation:
This function describes the value V of the investment after t years.
