Answer:
3 seconds
Step-by-step explanation:
We want to find t when h=0.
0 = 2t² -5t -3 . . . . . . . divide by -8
0 = (2t +1)(t -3) . . . . . . factor
The values of t that satisfy this equation are the values that make the factors zero: t = -1/2, t = 3. The positive value is the one of interest.
It takes 3 seconds for the object to hit the ground.
Answer:
Step-by-step explanation:
The time is inversely related to the number of people working so that as the number of people working increases, the time required decreases
t = k p
divide both sides by p
t/p =k
