V is already a function of h...
01
If:
and
=
write V as a function of h . Simplify the function so that you can express it as a polynomial in h .
My answer: 1st, I solved for R in the equation:
= and figured it to be: =
I then, plugged it into the equation
since I now know R. I am positive my answer is correct but the computer is rejecting it.
Here is my answer:
+350
Now that you've corrected the problem, I can help.
cross multiply
multiply out parentheses
subtract and divide
NOW you have r in terms of h.
So substitute
now simplify
If you need to simplify further I'm sure you can do it. You may not be inputting correctly into your computer.
