Answer:
![V =\frac{E}{IT}](https://tex.z-dn.net/?f=V%20%3D%5Cfrac%7BE%7D%7BIT%7D)
Step-by-step explanation:
You can isolate the "V" variable by dividing by IT on both sides:
![\frac{E}{IT} =\frac{VIT}{IT}](https://tex.z-dn.net/?f=%5Cfrac%7BE%7D%7BIT%7D%20%3D%5Cfrac%7BVIT%7D%7BIT%7D)
On the left, the IT from the top and bottom cancel, leaving you with just V:
![V =\frac{E}{IT}](https://tex.z-dn.net/?f=V%20%3D%5Cfrac%7BE%7D%7BIT%7D)
Answer:
$104.70
Step-by-step explanation:
The equation would be set up like this: 80.45 + 20.50(3) - 37.25. You started off with $80.45 in your bank account and deposited, or added, $20.50 every day on Tuesday, Wednesday and Thursday. That would mean you added $20.50 three times. Adding $80.45 + $20.50 + $20.50 + $20.50, simplified to $80.45 + $20.50(3) would get you $141.95 in total. Then, on Friday, you withdraw $37.25, getting the equation $141.95 - $37.25, leaving $104.70 for the weekend.

Answer:
The rate of change is
ft^(2)/min
Step-by-step explanation:
The area of a circle is given by the following equation:
![A(t) = \pi r^{2}](https://tex.z-dn.net/?f=A%28t%29%20%3D%20%5Cpi%20r%5E%7B2%7D)
To solve this question, we have to realize the implicit differentiation in function of t. We have two variables, A and r. So
![\frac{dA(t)}{dt} = 2\pi r \frac{dr}{dt}](https://tex.z-dn.net/?f=%5Cfrac%7BdA%28t%29%7D%7Bdt%7D%20%3D%202%5Cpi%20r%20%5Cfrac%7Bdr%7D%7Bdt%7D)
We have that:
.
We want to find ![\frac{dA}{dt}](https://tex.z-dn.net/?f=%5Cfrac%7BdA%7D%7Bdt%7D)
So
![\frac{dA(t)}{dt} = 2\pi*9*6](https://tex.z-dn.net/?f=%5Cfrac%7BdA%28t%29%7D%7Bdt%7D%20%3D%202%5Cpi%2A9%2A6)
![\frac{dA}{dt} = 108\pi](https://tex.z-dn.net/?f=%5Cfrac%7BdA%7D%7Bdt%7D%20%3D%20108%5Cpi)
Since the area is in square feet, the rate of change is in ft^(2)/min.
So the rate of change is
ft^(2)/min
