If an object is dropped from a height of 144 feet, the function h(t) = -16t2 + 144 gives the height of the object after t seconds. when will the object hit the ground? a) 9 seconds b) 6 seconds c) 1.5 seconds d) 3 seconds

So this question is asking for the zeros, or the x-intercepts, of this equation. For this, we have to set h(t) to zero to solve for it.

For this, we will be using the quadratic formula, which is (a = t^2 coefficient, b = t coefficient, and c = constant). In this case, our equation is . From here we can solve for t.

Since we cannot have negative time, the object hits the ground at 3 seconds, or D.

65°

step-by-step explanation:

the total measure of a triangle is 180 degrees. 62 + 53 is 115.

180 - 115 = 65

after simplifying it i got: -36.25 as my answer. hope that !
