Take the sqrt of both sides of <span>(x+2)^2=10:

x+2 = plus or minus sqrt(10)

Solve for x:  x = -2 plus or minus sqrt(10)

Evaluate x:  x = -2 + sqrt(10)  AND  x = -2 - sqrt(10)       (answers)

A population of rodents increases exponentially at a rate of 7.5% per year.
viktelen [127]
1. the answer is "0.62%".
We can calculate this as;
Rate = <span> 7.5% per year
there are 12 months in a year so,
= 7.5/ 100 x 1/12 
=0.075 x 1/12
= 0.00625
for percentage multiply it with 100,
= 0.00625 x 100 
=0.625% = 0.62%
2.
</span>the answer is "1.53%".
We can calculate this as;
Rate =  18.3% per year
there are 12 months in a year so,
= 18.3/ 100 x 1/12 
=0.183 x 1/12
= 0.01525
for percentage multiply it with 100,
= 0.01525 x 100 
=1.525% = 1.53%
