The distance required to stop a car varies
directly as the square of its speed. if 250 feet
are required to stop a car traveling 60 miles
per hour, how many feet are required to stop a
car traveling 96 miles per hour?

Need on this one asap im almost done with this subject

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?
