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
Solution to the system of equation (-2,5)
Answer:
The other length of the leg is <em>8 feet.</em>
Step-by-step explanation:
To find the answer we have to find what<em> 10</em> and <em>6 is squared.</em> <em>10 x 10 = 100</em>.
<em>6 x 6 = 36. </em>Now since we are trying to find the length of the other leg, we will <em>subtract 100 from 36</em> and we get <em>64</em>. Then for the last step, we will figure out what number<em> squared equals 64.</em> Because 8 x 8 = 64, <em>8 is our answer.</em>
Answer: He earned 0.831% interest in total.
Step-by-step explanation:
Given: Shawn earned $2.77 per day for three days as interest on his $1,000.00 investment.
Interest per day = $2.77
Interest in 3 days = 3 x ($2.77)
= $8.31
Invested amount= $1000
Required percentage of earnings = 

Hence, he earned 0.831% interest in total.
Answer:
10
Step-by-step explanation:
3x - 2 = 3(4) - 2 = 12 - 2 = 10
