Answer:
when x is 1 y is 7
when x is 2 y is 10
when x is 3 y is 13
Step-by-step explanation:
1) you have to find the difference between pipe A and pipe B, which is 6.40.
23.55-17.15=6.40
2) after finding the difference. You will take that difference and put it out of 23.55 and multiply by 100 to get your percentage. As so:
(6.40/23.55)(100)= 27.176% which rounds to 27% as a whole number.
Your answer is 27%. Hope that helps!
I don't see a square root sign anywhere, so I'll assume the integral is

First complete the square:

Now in the integral, substitute

so that

Under this change of variables, we have

so that

Under the right conditions, namely that cos(<em>t</em>) > 0, we can further reduce the integrand to


Expand the sine term as

Then


So the integral is

Answer:
PB = 15
Step-by-step explanation:
A midpoint is a point in the center of a line. Since P is the midpoint of AB, the length of AP = PB. Therefore, if AP = 15, PB = 15.
Answer:
3/7
Step-by-step explanation:
The ratio is the number of red marbles and the number of blue marbles in a fraction, so the ratio would be 3/7
