Tom opens a bank account and makes an initial deposit of $500. The banker tells Tom that he is going to revive an annual rate of
2 answers:
So for this you will be using an exponential equation, which is with a=initial value, b=growth/decay, y = total balance, and x = # of years
In this case, a = 500, and since with this problem the initial value is growing, you will add 100% to 6% to get 106%, or 1.06. The equation will be formed as such:
With this problem, just plug in 15 into x and solve for y:
In short, after 15 years Tom will have $1198.28 in his account.

To get the surface area of the sphere, we need to know the radius. Since the volume is given, we can get the radius.
Volume =
π r³
5000πm³ = π r³
5000m³ = r³
5000m³ x 3 = 4r³
= 
<span>
</span>∛3750 = ∛r³
r = 15.536m
r = 15.54m
Since the radius is now known, substitute it directly to the surface area formula
A = 4π x r²
A = 4π x (15.54)²
A= 3,034.67 m² or 3,035 m²
