The height h(t) , in feet, of a snowboarder t seconds after beginning a certain jump can be approximated by h(t) = -16t^2 +22.9t + 9. If the snowboarder lands at a point that is 4 feet below the base of the jump, determine the airtime (the time the snow boarder is in the air) for this jump. Round to the nearest tenth of a second.

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
