Answer:
Step-by-step explanation:
The work done changes the potential energy
ΔPE = mgΔh = 450(10)(50) = 225,000 = 225 kJ
power is the rate of doing work
P = 225000/5 = 45000 W = 45 kW
Answer:
The answer is 450 pi square feet
Step-by-step explanation:
C)-2/3is the answer because when your have 2/3+-2/3 will equal 0 in which justifies the additive inverse
Ok so if The area of the square is 15 * 15. then what you need to do is subtract the total area of the 4 white sectors of a circle.
Together, the 4 sectors form one circle of radius 7.5. Now yu need to have in mind that the area of the circle they jointly form is pi * (7.5)^2. So 15 * 15 - pi * (7.5)^2 =<span>48.29
