r²+6r+9=27+9
(r+3)²=36
r+3=±6
r=3, -9

A city has a population of 220,000 people. Suppose that each year the population grows by 7.25%. What will the population be aft

Archy [21]

Answer:

427,350

Step-by-step explanation:

so you do 7.25×13=94.25

and then you do 94.25%×220,000=207,350

So you can now do 207,250+220,000 (which) =427,350

What are the values of a and b?

ivann1987 [24]

Answer:

Step-by-step explanation:

Small triangles are similar. Therefore, the sides are proportional

$\dfrac{a}{20}=\dfrac{20}{21}$ <em>cross multiply</em>

$21a=(20)(20)$ <em>divide both sides by 21</em>

$a=\dfrac{400}{21}$

For b, we can use the Pythagorean theorem:

$b^2=\left(\dfrac{400}{21}\right)^2+20^2\\\\b^2=\dfrac{160000}{441}+400\\\\b^2=\dfrac{160000}{441}+\dfrac{176400}{441}\\\\b^2=\dfrac{336400}{441}\to b=\sqrt{\dfrac{336400}{441}}\\\\b=\dfrac{\sqrt{336400}}{\sqrt{441}}\\\\b=\dfrac{580}{21}$
