Answer:
7.92 years
Step-by-step explanation:
We want to find t such that ...
3 = 2^(t/5)
where 2^(t/5) is the annual multiplier when doubling time is 5 years.
Taking logs, we have ...
log(3) = (t/5)log(2)
t = 5·log(3)/log(2) ≈ 7.92 . . . years
It will take about 7.92 years for the population to triple.

10
The domain is the x intercept and the y intercept is the range
Answer:
V = 929.7
Step-by-step explanation:
Given the equation:
= 
The integral of the above equation is:
= 
Re-organizing the integrals:
= 
Integrating:
ln(CA) - ln(CA0) = 
Inputting the initial conditions of CA and the values of k and V0:
ln(7) - ln(100) = 
1.946 - 4.605 = -0.00286V
-2.659 = -0.00286V
=> V = 
V = 929.720
Approximating to one decimal place,
V = 929.7
EXPLANATION
Let's consider the facts:
a. Traveled = 16 feet
|-16| = 16
The porpoise is 16 feet from the surface of the water.
b. Withdrawal = -$250
|-250| = 250
Chelsea paid the electric company $250 dollars
c. Temperature = -54
|-54| = 54
The temperature is 54 degrees below zero.
d. Distance= 34 miles east
|34| = 34
The distance between Adelphi and Sterling is 34 miles.
