The height of a flare flown from the deck of a ship can be modeled by the function h = -16t^2+ 80t + 96, where h is the height of the flare above water in feet and tis
the time in seconds. How many seconds does it take the flare to hit the water?

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
