N=125b+50 where n= the total amount the company charges in dollars
Let's work out the process to find the numerator:
(x+2)/2 - (x+1)/3x Factor using the LCD, 6x
3x(x+2)/6x - 2(x+1)/6x
(3x² + 6x - 2x - 2)/6x
= (3x² + 4x - 2)/6x
Answer is 3x² + 4x - 2
Hopefully I did this correct, Not to good with math c':
Answer:
a. V = (20-x)
b . 1185.185
Step-by-step explanation:
Given that:
- The height: 20 - x (in )
- Let x be the length of a side of the base of the box (x>0)
a. Write a polynomial function in factored form modeling the volume V of the box.
As we know that, this is a rectangular box has a square base so the Volume of it is:
V = h *
<=> V = (20-x)
b. What is the maximum possible volume of the box?
To maximum the volume of it, we need to use first derivative of the volume.
<=> dV / Dx = -3
+ 40x
Let dV / Dx = 0, we have:
-3
+ 40x = 0
<=> x = 40/3
=>the height h = 20/3
So the maximum possible volume of the box is:
V = 20/3 * 40/3 *40/3
= 1185.185
The first term is 7, and the common difference is 4. We know this because 11-7=15-11=4. So the nth term is going to be 7+4(n-1). The 26th term will be 7+4(26-1)=7+100=107. The sum of the series is going to be (107+7)*13=1482.
The answer is A Because -22 is the opposite of 23
