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

Shannon orders 25,846 pounds of gravel for her driveway. What is this amount rounded to the nearest hundred pounds?

erica [24]

What is a hundred? A hundred would be 846. What does it mean to round to the nearest hundred pounds? It's to make the number end with 00, so 100, 200, 300. If you have 467, you'd round it to 500, because that's the closest hundred it can be rounded to. So the answer would 25,800.
