Answer:
Step-by-step explanation:
D: -25/27
-5/6 ÷ 9/10 = 5/6 x 10/9 *when diving fractions, use recipricals.*
-5/6 ÷ 10/9 = - 25/27 *just multiply each numerator and denominator*
It gives function: h = -16t^2 + 40
water is when height is 0 so solve for 0= -16t^2 + 40
subtract 40 from both sides: -40 = -16t^2
divide by -16: -40/-16 = t^2
simplify: 5/2 = t^2
square root both sides: 1.58 = t
