Answer:
<h2>The answer is B. (x-2)</h2>
Step-by-step explanation:
First simplify the equation (2x-3)-(x-1)
=(2x-3)-x+1
=(2x+3)-x-1
=2x-3-x-1
=x-2

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
Answer:
70 is answer
Step-by-step explanation:
Given that a function in x is
we have to find f'(7)
we know by derivative rule derivative of a function is
For finding out at 7 we replace x by 7
=
So f'(7) = 70
answer is 70
