The equation is h=-16t²+40t+5.The ball will hit the ground when h=0. So:
0=-16t²+40t+5
16t²-40t-5=0
Using the quadratic formula, we get a positive value for t of <span>2.61930639376 seconds.

Step-by-step explanation:
it's called answer is minus 7
c = total cost
h = hours
To find total cost you would need to multiply $40 per hour by the total number of hours (h) and add that to the flat fee of #00.
The equation would be C = 40h +300
Answer:
52488y²
Step-by-step explanation:
first solve for 3³. then solve for 18²
3³=27
18²=324
27*324=8748
then multiply 8748 by 6y²
=52488y^2
