Answer:
Step-by-step explanation:
<u>Use formula for continuous interest:</u>
- A =
, where r- interest rate, t- time in years
<u>If A = 3P, and r = 0.085 then the equation is:</u>


- ln 3 = 0.085t
- 1.099 = 0.085t
- t = 1.099 / 0.085
- t = 12.9 ≈ 13 years
Answer:
C. 30 ft
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
When we draw out a picture, we should see that we use the Pythagorean Theorem to help solve our missing height:
10² + b² = 32²
b² = 32² - 10²
b = √924
b = 2√231 or 30.3974
Round that to 30 feet.
