A football is kicked into the air with an upward velocity of 64 ft/s. It's height in feet after seconds is predicted by a quadratic function h(t) = - 16t^2 + 64t + 4 . At what point in time with the ball be at its maximum height and how high will the ball be in the air ?

Hi, can anyone show me how to do this problem? 100 points for this. in advance

The frequency table shows the results of a survey asking people how many hours they spend online per week. on a piece of paper, draw a histogram to represent the data. then determine which answer choice matches the histogram you drew. in order here is the.. hours online: 0-3, 4-7, 8-11, 12-15, and 16-19. frequency: 5, 8, 10, 8, 7 answer for the question is in the picture! : )

Answer asap! show all work! find the number of complex roots, the possible number of real roots and the possible rational roots of the polynomial function. then, solve for all roots. x^3 + 2x^2 + 3x + 6 = 0
