Answer:
<h2>The price is 860 dollars.</h2>
Step-by-step explanation:
The revenue of the company is given by 
, which is a polynomial of x, the price of the new phone.
The revenue of the company will be the highest, if 
, that is
1720 - 2x = 0
or, x = 860.
Hence, the price of the new phone to maximize the company's revenue is 860 dollars.

Answer:
1. 175 cubic ft
2. 42 cubic m
3.140 cubic m
4.216 cubic in
Step-by-step explanation:
The easiest way too solve this si to split the shapes up into two smaller shapes. For the first one split it into two rectangles, the long rectangle and the smaller rectangle down the bottom right. First we will do the smaller rectangle, multiply 7 by 2 and then multiply that by 5-3 (the bottom length minus the top length) and you get 28. 7(7x3) + 28. This equals 175. Because it is volume the answer is cubic. Repeat theses steps for the other 3 questions and that is how you solve it.
Answer:
-4
Step-by-step explanation:
To find the slope, you can use the formula y2-y1/x2-x1. Plugin any set of values. Say 13 is y2, and 5 is y1. 13-5=8. We now have 8/x2-x1. You have to use the x-values of the y-values that you already used. -2 is x2 and 0 is x1. -2-0=-2. 8/-2 = -4.
