Im pretty sure your answer is gonna be A) 15.5 .
SOLUTION
The object would hit the ground at the root of the equation, that is where h = 0
So we have

Solving the quadratic equation, we have

So we ignore -1 as time cannot be negative.
Hence the object hit the ground in 3 seconds
First, find the slope using the equation, y2 - y1 / x2 - x1
1-5 / 4 - - 4 = -4/8 = -1/2
plug this into slope intercept form
y = -1/2x + b
Next use one of the points to find b using point-slope form. I will use (4,1)
y - y1 = m ( x - x1)
y - 1 = -1/2 (x - 4)
y -1 = -1/2x + 2
+1 +1
y = -1/2x + 3 is your equation
48/15 = 3.2 round to nearest whole number (3)
48-3 = 45 men
Answer:
K=1
