60=5k is the answer for your question
6x-3(2x-3)=-3
6x-6x+9=-3
0x+9=-3
No Solution
The first box is "none of these" since it is not a vertical angle, is not an adjacent angles, and is not a linear pair, the second box is vertical angles
A. Convert to vertex form:-
= -0.8(x^2 - 4x) + 6
= -0.8 ((x - 2)^2 - 4)) + 6
= -0.8(x - 2)^2 + 9.2
Maximum height of the ball is 9.2 feet Answer
b. horizontal distance at this height = 2 feet. Answer
c. this distance will be the positive root of f(x) = 0
-0.8(x - 2)^2 = -9.2
(x - 2)^2 = 11.5
xi-2 = sqrt 11.5 = 3.39
required distance = 5.39 = 5.5 feet answer
