+335 The equation $y = -6t^2 + 51t$ describes the height (in feet) of a projectile launched from the surface of Mars at 51 feet per second. In how many seconds will the projectile first reach 108 feet in height?
+2094 Let's set the equation to
-6t^2+51t=108
Try if you can solve the equation :D
If you can't, I'll try to help!
+37146 Just put in 108 fr 'y' in your equation ...then solve for 't' using quadratic formul or factoring.... throw out any negative values for t
108 = -6t2 + 51 t
-6t2+51t - 108 = 0 now use quadratic formula or factoring to find the values of 't'
