14. The population of polar bears in the world is decreasing and can be modeled by the function t P(t)18600(.91). where t is the amount of years. Using this function, answer the following:

a) What is the initial population of polar bears?

b) What percent rate is the population decreasing by per year?

c) How many polar bears will there be in 5 years?

d) Which of the following choices approximately represents the amount of years it will be for the polar bear population to reach 8,000?
(3) 9
(2) 7
(1) 5
(4) 10

A ITS A BECAUSE I DONT KNOW

answer: $13,622.84

step-by-step explanation: check the picture for info and stats : )

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
