Answer:
The height of the rock formation is 
Step-by-step explanation:
see the attached figure to better understand the problem
we know that

solve for h

You could do the question the way it is written, but it is far easier to bring the negative power up to the numerator.
y= x^2 - 3. The derivative of that is
dy/dx = 2x The three is a constant and is always dropped when a derivative is taken
d(-3)/dx = 0
If you are a purist and want to solve the question the way it is written, you could do it this way.
dy/dx = d(1)/dx x^-2 - d(x^-2)/dx * 1
======================
(x^-2)^2
dy/dx = - (-2 x^ - 3) / x^-4
dy/dx = 2 x^-3 * x^4
dy/dx = 2 x^(-3 + 4)
dy/dx = 2x ^ 1
dy/dx = 2x <<<<< answer
Answer:
12/1
Step-by-step explanation:
k = y/x, where y and x is how much is added to the respective variables each point.
if Raleigh to Cleveland = 585 miles then Cleveland to Raleigh = 585 miles
585 miles + 585 miles = 1170 miles
1170 miles / 18 hours = 65 miles / hour
James drove 65 miles per hour.
