Answer: 8.73 ft/s
Step-by-step explanation:
We have the following equation that models the motion of the rock:
Where 
is the height of the rock at a time 
.
Now, if 
we can find and then the velocity of the rock at that height:
Rearranging the equation:
Multiplying the equation by -1:
Solving with the quadratic formula 
, where 
, 
, 
.
Choosing the positive result of the equation:
Since velocity 
is defined as the traveled distance in a given time , we have:
This is the velocity of the rock at the height of 48 feet
Answer:
y=0
Step-by-step explanation:
The equation for the slope is
m = ( y2-y1)/(x2-x1)
-2 = (4-y)/(1-3)
-2 = (4-y)/-2
Multiply each side by -2
4 = 4-y
Subtract 4 from each side
4-4 = 4-y-4
0 = -y
0=y

Answer:
the exact answer would be 651
Step-by-step explanation:
if you were to estimate I would say you should probably round up to 700
