Help me pls this is my last question. I don't understand how to even do this please help me. Nothing on this website is helping me please help. A ball is launched into the sky at 54.4 feet per second from a 268.8 meter tall building. The equation for the ball’s height, h, at time t seconds is h = -3.2t2 + 54.4t + 268.8. When will the ball strike the ground?

Find the value of x. give reasons to justify your solutions! h ∈ ig

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number?

Apiling for a high-rise building is pushed by two bulldozers at exactly the same time. one bulldozer exerts a force of 1250 pounds in a westerly direction. the other bulldozer pushes the piling with a force of 2650 pounds in a northerly direction. what is the direction of the resulting force upon the piling, to the nearest degree? a. 65 n of w b. 25 n of w c. 45 n of w d. 35 n of w
