Answer:
the earned value of the project is $9,900
Step-by-step explanation:
The computation of the earned value of the project is shown below:
As we know that
CPI = Earned value ÷ Actual cost
1.1 = Earned value ÷ $9,000
So, the earned value is
= 1.1 × $9,000
= $9,900
hence, the earned value of the project is $9,900
Answer:
b) π /16 (1-1/e^2)
Step-by-step explanation:
For this case we have the following limits:
And we have semicircles perpendicular cross sections.
The area of interest is the enclosed on the picture attached.
So we are assuming that the diameter for any cross section on the region of interest have a diameter of
And then we can find the volume of a semicircular cross section with the following formula:
And for th volum we can integrate respect to x and the limits for x are from 0 to 1, so then the volume would be given by this:
And evaluating the integral using the fundamental theorem of calculus we got:
And then the best option would be:
b) π /16 (1-1/e^2)
The answer is 6.7
You (should) know 10 goes into 67, 6 times. So write 6 on the top and subtract 60 from 67. You get 7. 10 doesn't go into 7 because 7 is less. So write a zero next to the 7 AKA bring down a 0. You will then technically have 70. 10 goes into 70, 7 times, so write 7 next to the previous 6 at the top, and put a decimal between 6 and 7.
Or
You should know if anything is being divided by 10. You just move the decimal to the left. Left is less. In 67 the decimal is right after the 7. 67.0. Therefore if you move the decimal one place over to the left you get 6.7
Either way works.
