Robert plays cricket. He hit the ball in such a way that it goes up 180 feet
PilotLPTM [1.2K]

Answer:

4 feet per second

Step-by-step explanation:

Hi there!

v=D/t where v is velocity (speed), D is distance and t is time

Plug in the known values (D=180 feet, t=45 seconds)

v=180/45\\v=4

Therefore, the speed of the ball is 4 feet per second.

I hope this helps!

What's the midpoint between (1,-7) and (-1,-23)
Alik [6]
Answer: (0,-15)

--------------------------------------------------

Explanation:

Add up the x coordinates to get 1+(-1) = 0. Divide this sum in half to get 0/2 = 0. Therefore the x coordinate of the midpoint is 0.

Repeat for the y coordinates. First add the y coordinates to get -7+(-23) = -30. Then divide that result in half to get -30/2 = -15. So the y coordinate of the midpoint is -15.

Overall, the midpoint is (0,-15).

Q(9,10) . R(-5,2) . S(-8,-2) . T (-1,2) . Parallel or Perpendicular
SVEN [57.7K]

Answer:

Perpendicular

Step-by-step explanation:

Put all the points on a graph.

Parallel means that the lines that have the same slope and different y-intercepts. Lines that are parallel to each other will never intersect.

On the graph we made we can see that the lines will have to intersect because the points are in positions that no matter which points we chose to connect together, they would intersect with the other line.
