Splitting up the interval [0, 6] into 6 subintervals means we have
![[0,1]\cup[1,2]\cup[2,3]\cup\cdots\cup[5,6]](https://tex.z-dn.net/?f=%5B0%2C1%5D%5Ccup%5B1%2C2%5D%5Ccup%5B2%2C3%5D%5Ccup%5Ccdots%5Ccup%5B5%2C6%5D)
and the respective midpoints are
. We can write these sequentially as
where
.
So the integral is approximately
Recall that
so our sum becomes
Answer:
B. -2
Step-by-step explanation:
2(x - 4) + 3x - x2
2(2 - 4) + 3(2) - (2)2
2(-2) + 6 - 4
-4 + 6 - 4
-8 + 6
-2
Answer:
y= 9x + 8
Step-by-step explanation:
Answer:
9,951.04
Step-by-step explanation:
First you find the area of the rectangle:
44x88=3,872
Then you add the area of the two semi circles:
A=1/2(pi)(r^2)
A= 3,039.52
Multiply the area above by 2 since there are two semi circles and they are the same size.
4*200+4*70+4*5, or you can just use a calculator.
