Answer:

Step-by-step explanation:
The midpoint of AB coordinates are:
where:

This would be y=+4(3x-1) because the y+x intercepts the middle causing,

Answer:
C 14
Step-by-step explanation:
7 ×4 ×1/2=14
because triangle area formula is A=1/2×B×H
B= base
H= height
Answer:
a) How much work has he done = dW = 1.3 × 105 J
b) What is the magnitude of the heat that he has lost = dQ = -5.4 × 105 J
Step-by-step explanation:
- From the first law of thermodynamics; dQ = dU + dW
Hence, work done dW = dQ - dU
dW = -6.7 × 105 J - ( -8.0 × 105 J)
dW = 1.3 × 105 J is the work done by the player
- for heat lost; from dQ = dW + dU
- dU = -8.0 × 105 J and dW = 2.6 × 105 J
- heat lost dQ = 2.6 × 105 J + ( -8.0 × 105 J)
- The negative is as a result of heat lost by the player
