D. $8,962.50
P stands for principal
R stands for rate
T stands for time
A=$7,500(1+ (0.039×5))=$8,962.5
A=$8,962.50
So Jake will have $8,962.50 of interest after 5 years.
Answer:
Step-by-step explanation:
Using the disk method, the volume is given by the integral

That is, each disk has a radius of <em>y</em> = 9 sin(<em>x</em>) and hence area = <em>π</em> (9 sin(<em>x</em>))². Add up infinitely many such disks by integrating. Then the volume is

The side that has length 24 equals to 4y + 8
24 = 4y + 8
24 - 8 = 4y
16 = 4y
y= 16÷4
y = 4
The side that has length 31 equals to 7x - 4
7x - 4 = 31
7x = 31 + 4
7x = 35
x = 35 ÷ 7
x = 5

Step-by-step explanation:
Using the chain rule: dp/dx=(dp/dt)/(dx/dt).
So, you can calculate dp/dx=2x^(-1/2)=2/√x.
by my original statement (rearranged a little) dx/dt (which is what you're looking for) is equal to (dp/dt)/(dp/dx), so subbing in x=1900 you get 1000√1900/2=21794.495 units/month increase in sales.
