No. when plugging 4 into the equation, 0 is not the final result. instead it is 6.
square root of 2(4)+1 = square root of 9 = 3
3+3 = 6
and 6 is not 0 so x cannot = 4
The number of seconds it takes for the waste to hit the ground for the given function is: 5 seconds.
<h3>How to Evaluate a Function?</h3>
We are given the function of height to time as, h(t) = -16t² + initial height, and we have the following:
- h(t) = 0 (height of the ground is 0)
- t = seconds the waste takes to height the ground
- Initial height = 400 feet
Plug in the values into the equation of the function
0 = -16t² + 400
Solve for t
0 - 400 = -16t²
-400 = -16t²
-400/-16 = t²
400/16 = t²
√(400/16) = t
20/4 = t
5 = t
t = 5
The number of seconds it takes is: 5 seconds.

5 + 8 = 13
169/13 = 13
13 * 5 = 65
13 * 8 = 104
Thus, 65:104

Step-by-step explanation:
its simple really.
The mapping rule for a 180 degree rotation is:
(x,y) (-x,-y)
1. Multiply the x-coordinate by -1.
2. Multiply the y-coordinate by -1.
3. SImplify
So the coordinate after a 180 degree rotation is: (5,-1)
