Answer:
(4.75, 2.25)
Step-by-step explanation:
Given the coordinate (x,y). If this coordinate is reflected over the x axis, the resulting coordinate will be (x, -y)
Note that the y coordinate was negated.
Let the original point needed be (x, y)
If the new point is located at (4.75, -2.25)
Since the y coordinate was negated, then;
-y = -2.25
y = 2.25
x = 4,75 (x coordinate remains the same)
Hence the original point is (4.75, 2.25)
Answer:
3.16
Step-by-step explanation:
At the ground, h = 0.
h = -16x^2 + 160
0 = -16x^2 + 160
16x^2 = 160
x^2 = 10
x = +\- sqrt(10)
Since we cannot have a negative time, we discard the negative answer.
