Answer:
$9891.23
Step-by-step explanation:
The formula for future value of annuity due is:
Where,
- FV is the future value of the annuity (what we need to find)
- P is the periodic payment (here it is $400)
- r is the interest rate per period (here 13% yearly interest is actually percent per period(quarter))
- n is the number of periods (here the annuity is for years, which is periods, since quarterly and there are 4 quarters in 1 year)
Substituting all those values in the equation we get:
Hence, the future value of the annuity due is $9891.23
Average rate of change can be calculated by the following
Δy/Δx
Our Δx refers to displacement.
Δx = 4 - 64 = -60
Our Δy refers to our Δf(x)
To get our f(x) values, we must plug in 64 and 4 into the function f(x)
f(64) = 8√64 = 64
f(4) = 8√4 = 16
Δf(x) = 16 - 64 = -48
So our rate of change is -60/-48 = 0.8
I believe the answer should be positive 0.8, but that's my best estimate.
