[Calc 1] An explanation on how to best solve this. I've been stuck trying to use chain rule
1 answer:
Answer:
G'(y) = 4y^7(y+4)/(y+2)^5
Step-by-step explanation:
Work it a piece at a time.
Define z = y^2/(y+2). Then your derivative is found from the power rule as ...
G = z^4
G' = 4z^3·z'
Now, define z = u/v. Then your derivative is found using the quotient rule:
z' = (vu' -uv')/v^2 = ((y+2)(2y) -(y^2)(1))/(y+2)^2
Putting this together we have ...

Mr. Jackson invested $800 at 6% per year and $ 2400 at 4 % per year
<h3><u>Solution:</u></h3>Mr. Jackson invested a sum of money at 6% per year, and 3 times as much at 4% per year.
Let the sum invested be ‘a’ and ‘3a’ at 6% per year and 4 % per year respectively
Also, his annual return totaled $144
We can form following equation on the basis of question:-
a = $800
The amount of money invested at 6% = a = 800
The amount of money invested at 4 % = 3a = 3(800) = 2400
So, the amount of money invested at 6% is $800 and the amount of money invested at 4% is $ 2400
