Answer:
t = 5 s
Step-by-step explanation:
The function that gives the height in feet of the ball t seconds after it is thrown is :
We need to find how long will it be before the ball hits the ground. When it hits the ground, its height will be equal to 0.
So,
We need to solve this equation. When we solve, we get its solution as shown in the figure. We can see that t = -2 s and t = 5 s.
t = -2 s is not possible.
Hence, the ball will hit the ground before 5 seconds.
Answer:
3/20 tons = 300 pounds
4 tons = 8000 pounds
14000 pounds = 7 tons
Step-by-step explanation:
1 ton = 2000 pounds
This would be your answer
So C= dxpi or rx2xpi= c in this case 7x 2 = 14 is diameter do E D and A finds the diameter and the rest do not
