I NEED HELP The height h (in feet) of an object t seconds after it is dropped can be modeled by the quadratic equation h = -16t2
+ h0, where h0 is the initial height of the object. Suppose a small rock dislodges from a ledge that is 255 ft above a canyon floor. Solve the equation h = -16t2 + 255 for t, using the quadratic formula to determine the time it takes the rock to reach the canyon floor. (A) t ≈ 0.87 s (B) t ≈4 s (C) t = 8.5 s (D) t = 16 s
First you would divide mile by hours, so: 125/212 which gives you .59 miles per hour so then you would multiply .59 by 6 which gives you 3.45 miles per hour. Hope it helps!!
