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

Determine the value for x in the picture below. Please help me

Alex787 [66]

Given:

The figure of a right angle triangle.

A line segment intersect the two sides and parallel to third side of the triangle

To find:

The value of x.

Solution:

According to basic proportionality theorem, if a line segment intersect the two sides and parallel to third side of the triangle, then it divides the two sides proportionally.

Using basic proportionality theorem, we get

$\dfrac{8}{20-8}=\dfrac{6}{x}$

$\dfrac{8}{12}=\dfrac{6}{x}$

$\dfrac{2}{3}=\dfrac{6}{x}$

On cross multiplication, we get

$2\times x=6\times 3$

$2x=18$

$x=\dfrac{18}{2}$

$x=9$

Therefore, the value of x is 9.

Which of the following is a parent function?

Nesterboy [21]

A parent function is the simplest formula in which no transformations have been made. This is seen in the form of y=x^2.
