70% divided by 25 is 2.8 so add 2.8 to 110 you get 112.8 so 112.8 is your answer hope this helps
Answer:
5. (x-8)(x+2)
10. (x-5)(x-5) OR (x-5)^2
Answer:
<em>It will take 9 years for the population to double</em>
Step-by-step explanation:
<u>Exponential Growth
</u>
The natural growth of some magnitudes can be modeled by the equation:

Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.
The population of a city grows at a rate of r=8% = 0.08 per year. We are required to find when (t) the population will double, or P=2Po.
Substituting in the equation:

Simplifying:

Taking logarithms:

Applying the exponent property of logs:

Solving for t:

Calculating:

It will take 9 years for the population to double
Answer:
Area of circle = πr^2
Area of circle when diameter is 2x; r=x
=πx^2
