Answer: Approximately 8.78 million

Step-by-step explanation:

Since the population is growing at a rate of 3.1% each year, that is synonymous to percentage increase

%increase = increase/initial population × 100

Or

(3.1 + 100)/100 × initial population = 9.05 million

= 1.031 × initial population = 9.05 million

Initial population = 9.05million/1.031

Initial population = 8.78 million

Let f(x)=x2+15x+56
Ivan

Answer:

-8, -7

Step-by-step explanation:

f(x)=x^2+15x+56

0 =x^2+15x+56

What two numbers multiply together to make 56 and add together to 15

7*8 = 56

7+8=15

0 = (x+8) (x+7)

Then use the zero product property

x+8 =0     x+7 =0

x+8-8 =0-8        x+7-7 =0-7

x=-8                      x=-7
