The answer would be B. (4,0)
Because you are pretty much reflecting the point from the 1st quadrant to the 2nd quadrant

A
The point (-4,0) lies on the x-axis. The line y=0 IS the x-axis. The point would be in the same place after a reflection.

Answer:

Step-by-step explanation:

To solve this problem you need the function

 

h(t) = -16t2 + v0t + h0

where t = time

v0 is the initial velocity, which in our case is 0

h0 = initial height, which in our case is 256

h(t) = 0 since we want to know when the ball will hit the ground.

 

0 = -16 t2 + 256

 

And we can solve for t

 

If we rearrange the terms we see that this is a difference of 2 squares

0 = 256 - 16t2

 

0 = (16-4t)(16+4t)

Setting each factor = 0

16-4t=0       16+4t=4

t = 4             t = -4

 

The second solution is discarded as time cannot be negative.

 

So the ball will hit the ground in 4 seconds.

A farmer pumps water from an irrigation well to water his field. the time it takes to water the field varies inversely with the
Mila [183]
In order to answer this question, we use the concept of ratio and proportion wherein we use the equation,
                                 R1 / T2 = R2 / T1
where R is for rate and T is for time. Substituting the known values to the equation,
                                 (600)/x = (400)/ 20
The value of x from the equation is 30. Thus, it will take 30 hours if the rate was adjusted to 400 gallons per minute.
