What is the average rate of change of the function y = cos(x) over the interval [0,2]?

Amodel rocket is launched from a roof into a large field. the path of the rocket can be modeled by the equation y = -0.04x^2 + 8.6x + 4.8, where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above the ground. how far horizontally from its starting point will the rocket land? a. 0.56 m b. 215.56 m c. 431.11 m d. 215.74 m

Solve each quadratic equation by factoring and using the zero product property. n^2 - 49 = 0

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
