A professional stunt performer at a theme park dives off a tower 21 m high into the water. His height above the ground at time t seconds is given by the equation h= -4.9t^2 + 21. a) How long does it take to reach the halfway mark?

b) How long does it take to reach the water?

c) Compare the times in (a) and (b). Explain why the time at the bottom is not twice the time at the halfway point.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
