URGENT WILL GET 20 and Brainlest

My name is Ann [436]

The polynomial that represents the difference between the cost of distributing by train and the cost of distributing by truck is:

$f(x) = -0.04x^2 + 18x + 75$

Solution:

The cost of distributing by train can be modeled as:

$-0.07x^2 + 40x - 105$

The cost of distributing by truck can be modeled as:

$-0.03x^2 + 22x - 180$

where x is the number of tons of product distributed

To find: Difference between the cost of distributing by train and the cost of distributing by truck

Difference = cost of distributing by train - cost of distributing by truck

Let f(x) = difference in cost between trains & trucks

$f(x) = (-0.07x^2+40x-105) - (-0.03x^2 +22x - 180)$

$f(x) = -0.07x^2 + 40x -105 + 0.03x^2 -22x + 180$

$Combine\ the\ like\ terms\\\\f(x) = -0.07x^2 +0.03x^2 + 40x - 22x +180-105\\\\Add\ the\ like\ terms\\\\f(x) = -0.04x^2 + 18x + 75$

Thus polynomial that represents the difference between the cost of distributing by train and the cost of distributing by truck is found

Find (f∘g)(x). f(x)=5x+1 g(x)=2x Write your answer as a polynomial in simplest form.

vladimir2022 [97]

(f o g)=f(g(x))
just sub
f(g(x))
sub g(x) for x in f(x)
g(x)=2x
2x=x in f(x)
f(g(x)=f(2x)=5(2x)+1=10x+1

(f o g)=10x+1
