Answer:
Pierre operates at a greater power level than Marie.
Marie and Pierre do the same amount of work
Step-by-step explanation:
Mass of crate=60kg
Height of truck bed=1 m
Time=3s
Pierre's work done=
Using formula Work done=mgh
Where m=mass of object
g=Acceleration due to gravity=9.8
Power=
Using the formula
Pierre's power=
Mass of box=2.5Kg
Total number of boxes=24
Total mass of boxes=
Time=2 min=
1 min=60 s
Marie;s work done=
Marie's power=
Pierre operates at a greater power level than Marie.
Marie and Pierre do the same amount of work
<span>The expression given (27x^2)z/(-3x^2)(z^6), can be simplify as below:
By properties of powers, if you have the same base, you can substract the exponents. Then:
=(</span>27x^2)z/(-3x^2)(z^6)
=-9z/z^6 (As you can see: x^2-2= x^0=1)
=-9/z^5 (Then, z^6-1=z^5)
<span>
Therefore, the answer is: The exponent on the variable z is 5.</span>
