Aball is thrown upward from the top of a building. the function below shows the height of the ball in a relation to sea level, f(t), in feet, at different times, t, in seconds:
f(t) = - 16t^2 + 48t + 160
the average rate of change of f(t) from t = 3 seconds to t = 5 seconds is feet per second

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0

Someone answer asap for ! a ball is rolled down a ramp. the height, f(x), in meters, of the ball x seconds after it is released is modeled by the function f(x) = x²- 10x + 25 for all values of x from 0 to 5. which statement about the ball is true? a. the maximum height of the ball is 5 meters b. the height of the ball increases from 0 to 5 meters above the ground. c. the ball has traveled 5 meters when it reaches the bottom of the ramp. d. the ball has been traveling for 5 seconds when it reaches the bottom of the ramp

Which of these triangle pairs can be mapped to each other using a single translation? cof hn
