A rocket is launched from a tower. The height of the rocket, vin feet, is related to the time after launch, x in seconds, by the giren equation. Using this equation, find the
time that the rocket will hit the ground, to the nearest 100th of second
y = - 16x^2 +147x +80

Arestaurant gives out a scratch-off card to every customer. the probability that a customer will win a prize from a scratch-off card is 25%. design and conduct a simulation using random numbers to find the experimental probability that a customer will need more than 3 cards in order to win a prize. justify the model for your simulation, and conduct at least 10 trials.

Let hh represent the number of hummingbirds and ss represent the number of sunbirds that must pollinate the colony so it can survive until next year. 6h+4s > 746h+4s> 74 this year, 88 hummingbirds pollinated the colony. what is the least number of sunbirds that must pollinate the colony to ensure that it will survive until next year?

If a || b and e || f , what if the value of y ?
