An unusually wet spring has caused the size of a mosquito population in some city to increase by 9% each day. If an estimated 259.900 metres are in the city on May 7, find how many mosquitoes will inhabit the city on May 15. Use y = 200.000(1.097 where x is number of days since May 7
On May 15 there will be approximately magitoes
(Round to the nearest thousand as needed.)

answer:

your answer is: c. 196 7/8 in^3.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
