Answer:
3.25 years (nearest hundredth)
Step-by-step explanation:
<u>Compound Interest Formula</u>
where:
- A = final amount
- P = principal amount
- r = interest rate (in decimal form)
- n = number of times interest applied per time period
- t = number of time periods elapsed
Given:
- A = $4916
- P = $4000
- r = 6.4% = 0.064
- n = 4 (quarterly)
Substitute the given values into the formula and solve for t:
Therefore, it will take 3.25 years (nearest hundredth) for the account to grow to $4916.

The length of the hypotenuse of right triangle ΔDEF is 50.44 units
<h3>How to find hypotenuse of a right triangle?</h3>The hypotenuse side can be found using Pythagoras theorem,
Therefore,
c² = a² + b²
where
- c = hypotenuse
- a and b are the other legs.
Therefore,
x² = 39² + 32²
x² = 1521 + 1024
x = √2545
x = 50.4479930225
x = 50.44
