We take the equation d = -16t^2+12t and subtract d from both sides to get
 0 = -16t^2+12t - d
We apply the quadratic formula to solve for t. With a = -16, b = 12, c = -d, we have
 t = [ -(12) ± √( 12^2 - 4(-16)(-d) ) ] / [2 * -16]
 = [- 12 ± √(144-64d) ] / (-32)
 = [- 12 ± √16(9-4d)] / (-32)
 = [- 12 ± 4√(9-4d)] / (-32)
 = 3/8 ±√(9-4d) / 8
The answer to your question is t = 3/8 ±√(9-4d) / 8

Find the side of a square whose diagonal is of the given measure. Given = 15.2 cm

Neko [114]

Answer:

15cm

Step-by-step explanation:

First, a square's diagonal is basically the hypotenuse of a 45-45-90 triangle. a 45-45-90 triangle has a really special relationship, where the side length is x, and the diagonal is x $\sqrt{2}$ . So, the side length is 15.
