Answer:   4095

<u>Step-by-step explanation:</u>

He sold 1 car on the first day so the first term (a) is 1. The amount doubles each month so the ratio (r) is 2.

Input those values into the Sum formula:

S_n=\dfrac{a(1-r^n)}{1-r}\\\\S_{12}=\dfrac{1(1-2^{12})}{1-2}\\\\.\quad=\dfrac{1-4096}{-1}\\\\.\quad=\dfrac{-4095}{-1}\\\\.\quad=4095

If m(x) =x+5/x-1 and n(x) = x - 3, which function has the same domain as (mºn)(x)?
GREYUIT [131]

We have

M(X) = (X + 5)/(X - 1)

N(X) = X - 3

So,

M(N(X)) =  [(X - 3) + 5]/[(X - 3) - 1]

<h3>M(N(X)) =  [X + 2]/[X - 4]</h3>

The M(N(X)) domain will be:

D = {X / X ≠ 4}

4 ∉ to the M(N(X)) domain, otherwise we would have a/0, which is not possible (a denominator with zero). An equivalent function would be

H(X) = 1/(X - 4)
