Mathematics

Step-by-step explanation:

(xm, ym) = ((x1+x2)/2, (y1+y2)/2)

(xm, ym ) = midpoint

(x1, y1) and (x2, y2) are the 2 points.

xm = (-3 + -12)/2 = -15/2 = -7.5

ym = (7 + 8)/2 = 15/2 = 7.5

the midpoint is (-7.5. 7.5)

Hi! To solve this question you need to use the midpoint equation, which is (x2+x1 / 2) , (y2+y1 /2). You can plug in values for this equation, making it (-12 + -3 /2), (8+7 /2). This will equate to (-15/2), (15/2). The final midpoint to this equation will be:

(-7.5),(7.5)

1. A 20 kg object is thrown with an initial upward velocity of 2 m/s. If air resists motion of the object by 4 N for each m/s, w
dlinn [17]

Answer:

  49 m/s

Step-by-step explanation:

We don't know what your model is, so we'll solve this based on the balance of forces. Air resistance exerts an upward force of ...

  (4 N/(m/s))v

Gravity exerts a downward force of ...

  (20 kg)(9.8 m/s²) = 196 N

These are balanced (no net acceleration) when ...

  (4 N/(m/s))v = 196 N

  v = (196 N)/(4 N/(m/s)) = 49 m/s

The terminal velocity is expected to be 49 m/s.
