Find the inverse of the following function: f(x) = 5/ square root of x, for x > 0

2 answers:

The inverse is y = (5/y)^2

You can get this by switching the x and y values and then solving for your new y.

x = 5/sqrt(y) ----> Multiply both sides by sqrt(y)
sqrt(y)*x = 5 ---> divide both sides by x
sqrt(y) = 5/x ---> square both sides
y = (5/x)^2

Your on a roller coaster your velocity is 13 ft./s are you moving up or down what is your speed

vladimir1956 [14]

Your speed is 13 ft/sec. In order to know our velocity, we would need to know what direction we're moving. You haven't told us anything about our direction, only that our speed is 13 ft/sec.
