Could someone help me on how to do this Balanced model project? I don't quite understand on how to complete it.

1. a parachutist is 800 feet above the ground when she opens her parachute. she then falls at a constant rate of 5 feet per second. select the equation that represents this situation. h = -800t + 5 y = -5x + 800 h = 5t - 800 y = 800x + 5 i need

Which of the functions graphed below has a removable discontinuity?

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 4x^2 - 19x- 5
