Hi there
The formula is
A=p (1+rt)
We need to solve for t
T=[(A/p)-1]÷r
Where
A future value 2200
P present value 1000
R interest rate 0.08
T time?
So
T=((2,200÷1,000)−1)÷0.08
T=15 years
Another time like this question you should post in at mathematics subject
Hope it helps
Assuming we don't know the speed capabilities of the tractor, the time it would take simply be the rate in miles per hour. It has a direct correlation between speed and time spent, so the miles the tractor needs to plow is unneeded.
Answer:
Last Option
Explanation:
I'm not sure about this one so I had to google the equation real quick.
The equation for the derivative of an inverse is:
![[f^{-1}(x)]'=\frac{1}{f'(f^{-1}(x))}](https://tex.z-dn.net/?f=%5Bf%5E%7B-1%7D%28x%29%5D%27%3D%5Cfrac%7B1%7D%7Bf%27%28f%5E%7B-1%7D%28x%29%29%7D)
From my understanding of the format, it might look like a hard equation to understand but its pretty simple.
The inverse derivative is 1 divided by the derivative of f(x), except you plug in f⁻¹(x) into that derivative.
Answer:
B. 25
Explanation:
Average Rate of Change is solved using:


![=\frac{[2(10)^2+(10)]-[2(2)^2+(2)]}{10-2}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5B2%2810%29%5E2%2B%2810%29%5D-%5B2%282%29%5E2%2B%282%29%5D%7D%7B10-2%7D)


The body is divided into several different systems. Do you need examples of the systems?
