Which expression has a value that is equivalent to the given expression when n = 8? 2n + 10 a. 3n b. 2(n + 5) c. n² + 5 d. 10n + 2

Use the data on the dot plot to answer the question. how many people read for more than three hours last week? i'm on a unit test review

The height of a flare fired from the deck of a ship in distress can be modeled by h(t)= -2(8t^2-52t-28), where h is the height of the flare above water and t is the time in seconds. a. find the time it takes the flare to hit the water.

Aprojectile is thrown upward so that its distance above the ground after t seconds is given by the function h(t) = -16t2 + 704t. after how many seconds does the projectile take to reach its maximum height?
