Answer:

The answer is the option C

V=38.37\ ft/sec

Step-by-step explanation:

we have that

V=\sqrt{64h}

In this problem we have

h=23\ ft

Substitute in the formula and solve for V

V=\sqrt{64(23)}

V=\sqrt{1,472}\ ft/sec

V=38.37\ ft/sec

V = sqrt (64h)
V = sqrt (64 * 23)
V = sqrt 1472
V = 38.366 rounds to 38.37 ft <==

Answer:

<h2><em><u>-4</u></em></h2>

Step-by-step explanation:

The equation is y = slope + or - y-intercept

Slope = mx

So the slope is -4

The slope can be found also by having 2 points and doing (y2 - y1)/(x2 - x1). Also, you can do rise over run. These are options for if you have a graph.

Hope this helped,
