We use the formula for exponential growth:
P = Po exp(kt)
Using the population data from 1993 to 1996, we can solve for the growth rate k
76 = 72 exp(k(3))
76/72 = exp(3k)
ln (76/72) = 3k
k = ln(76/72) / 3 = 0.0180
In 10 years (2003), the population will be:
P = Po exp(0.0180t)
P = 72 exp(0.0180(10))
P = 86.22 million

Answer:
Raul's age is 15 years.
Step-by-step explanation:
r represents Raul's age.
The number of years from the start of the Great Depression to the first presidential election of Richard Nixon is six years less than three times Raul's age.
The first presidential election happened 39 years after the Great Depression and six years less than three times Raul's age is 3r - 6.
Therefore, 3r - 6 = 39
Add 6 to both sides.
3r = 45
Divide both sides by 3.
r = 15
Hence, Raul's age is 15 years.
Answer:
Ruby pays a dollar every 12 messages.
Step-by-step explanation:
It costs Ruby $4 to send 48 text messages. To find the unit rate, you would divide 48 by 4. So the result would lead to 12 messages per dollar.
