Answer:
y = 2x + 12
Step-by-step explanation:
Get the standard form equation into y = mx + b form.
Then, use the recipricol of the m value to get the slope for the perpendicular line.
Then, plug in the point and solve for the b value.
Work :
y = -1/2x-5/4
Perpendicular line slope : 2
y = 2x + b
-4 = 2(-8) + b
-4 = -16 + b
b = 12
y = 2x + 12
Answer:
c
Step-by-step explanation:
0.0125
so it is 1.25 because the thousand place onward, it is in the decimal place of the percent
Answer D). 9 ft is correct
Height of the ball at a horizontal distance of 10 feet is 9 ft
Step-by-step explanation:
A ball is thrown and it follows a parabolic path. At each horizontal distance (x) the following equation models the ball’s height (y).
Y(x) = 
Question asked is " What will be height (Y) of the ball when X=10 ft "
Simply putting value of X in given equation
we get,
Y(x) = 
Y(x) = 
Y(x) = 
Y(x) = 
Y(x) = 
<em>Therefore,</em> Height of the ball at a horizontal distance of 10 feet is 9 ft
Answer D. 9 ft is correct
