11(7) - 2
77 - 2 = 75
x= 7
Answer:
Step-by-step explanation:
V=4/3πr³
v = 1.33*3.142*9³
v = 3046.39in³
New scale = 3046.39*1.5
= 4,569.59in³
Coefficient is the number before your variable. :)

Answer:
The population in 20 years will be 781.
Step-by-step explanation:
The population of the town can be modeled by the following equation:

In which P(t) is the population after t years, P(0) is the initial population and r is the growth rate, as a decimal.
The initial population of 500 increases by 25% in 10 years.
This means that 
We use this to find r.



Applying ln to both sides




So

What will be the population in 20 years
This is P(20)

The population in 20 years will be 781.
