Answer:
3.6 s
Step-by-step explanation:
This is nicely solved by a graphing calculator. It takes about 3.6 seconds to hit the ground.

We notice that the vertical velocity is a multiple of the leading coefficient, so we can solve this by completing the square.
0 = -4.9(t^2 -2t) +28 . . . . . for h = 0
28 +4.9 = 4.9(t^2 -2t +1) . . . . . rearrange, add 4.9 to both sides
32.9/4.9 = (t -1)^2
1 +(1/7)√329 = t ≈ 3.5912. . . . . square root and add 1
It takes about 3.6 seconds for the watermelon to hit the street.
Answer:the answer is B : -250
Step-by-step explanation:
Ok, so you want us to find theta when

we know from our unit circle that when the angle is 45 degrees, cos(45°)=sin(45°)=

also we can find this by the special 45-45-90 triangle
when Θ=45°, cos(Θ)=
