Select the correct answer. An experiment observing the growth of two germ strand populations finds these patterns.
. The population of the first germ is represented by the function A(z) = (1.3)5+9
• The population of the second germ is represented by the function B(s) = (1.3)*5+1
Which function best represents function R, the ratio of the population of the second germ to the population of the first germ?
OB. RO
OA. R(x) = (2.6)4:249
(1.3)5=+10
R(x) =
(2.6)35-8
R(x) =
(1.3)85-8

Help please

idk idk idk idk idk

step-by-step explanation:

i think the answer would be c

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
