Please help! A rocket carrying fireworks is launched from a hill 80 feet above a lake. The rocket
will fall into lake after exploding at its maximum height. The rocket's height above
the surface of the lake is represented by h = –16t2 + 64 t + 80. How many
seconds after the rocket launched will it hit the lake?

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.

answer: 5

step-by-step explanation:

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
