What are the zeros of the polynomial function? F(x)= x^2 + 12x +20

vampirchik [111]

Answer:

Step-by-step explanation:

$F(x)=x^2+12x+20\\\\\text{The zeros:}\\\\F(x)=0\iff x^2+12x+20=0\\\\x^2+2x+10x+20=0\\\\x(x+2)+10(x+2)=0\\\\(x+2)(x+10)=0\iff x+2=0\ \vee\ x+10=0\\\\x+2=0\qquad\text{subtract 2 from both sides}\\\boxed{x=-2}\\\\x+10=0\qquad\text{subtract 10 from both sides}\\\boxed{x=-10}$

It has been estimated that the population of Indianapolis is growing at a rate of 0.9% per year. Assuming that population growth

Mumz [18]

Answer:

2,136,605

Step-by-step explanation:

To estimate growth, we use the formula shown below:

$F=P(1+r)^t$

Where

F is the future amount (we want to find for Jan 2024)

P is the present amount (present population of 1,988,817)

r is the rate of growth (0.9% means 0.009)

t is the time in years (from Jan 2016 to Jan 2024 is 8 years, t = 8)

Let's put these into the formula and figure out F:

$F=P(1+r)^t\\F=1,988,817(1+0.009)^8\\F=2,136,604.5$

Rounding we get the population in Jan 2024 to be 2,136,605
