frozen [14]

Answer:

The answer is: 83 + 12√35

(a + b)² = a² + 2ab + b²

In (2√5 + 3√7)², a = 2√5, b = 3√7

Just substitute a and b:

(a + b)² = a² + 2ab + b² = (2√5)² + 2 * 2√5 * 3√7 + (3√7)² = 

           = 2²√5² + 2 * 2 * 3 * √5 * √7 + 3²√7² =

           = 4 * 5 + 12 * √(5*7) + 9 * 7 =

           = 20 + 12 *√35 + 63 =

           = 83 + 12√35

The population of Atlanta is 5,949,951. It is said to be growing at a rate of 1.3% yearly. What will the population be in 10 yea
ira [324]

Answer:

6770299

Step-by-step explanation:

To work this out you would first divide 1.3 by 100, which gives you 0.013. Then you would add 0.013 to 1, which gives you 1.013. This is because you are finding a percentage increase and so you would convert the percentage to a decimal and add it to 1. Then you would multiply 5949951 by 1.013 to the power of 10. This is because you are finding the percentage increase over a span of 10 years.

1) Divide 1.3 by 100.

1.3/100=0.013

2) Add 0.013 to 1.

0.013+1=1.013

3) Multiply 5949951 by 1.013 to the power of 10.

5949951*1.013^{10} =6770298.9019004

4) Round to the nearest whole number.
