The equation y = -6t^2 + 43t describes the height (in feet) of a projectile  seconds after it is launched from the surface of Mars at 43 feet per second. In how many seconds will the projectile first reach \(27 \) feet in height? Express your answer as a decimal rounded to the nearest tenth.

So the variable y is set to 27 to answer the question. t is seconds, so we can solve for t. -6t^2 + 43t - 27 = 0

Quadratic formula is applied

t = 0.7 seconds.
