The summand (R?) is missing, but we can always come up with another one.
Divide the interval [0, 1] into
subintervals of equal length
:
![[0,1]=\left[0,\dfrac1n\right]\cup\left[\dfrac1n,\dfrac2n\right]\cup\cdots\cup\left[1-\dfrac1n,1\right]](https://tex.z-dn.net/?f=%5B0%2C1%5D%3D%5Cleft%5B0%2C%5Cdfrac1n%5Cright%5D%5Ccup%5Cleft%5B%5Cdfrac1n%2C%5Cdfrac2n%5Cright%5D%5Ccup%5Ccdots%5Ccup%5Cleft%5B1-%5Cdfrac1n%2C1%5Cright%5D)
Let's consider a left-endpoint sum, so that we take values of
where
is given by the sequence

with
. Then the definite integral is equal to the Riemann sum

Answer:
Width = 12
Length = 16
Step-by-step explanation:
Width = x
Length = x + 4
2x + 2(x+4) = 56
2x + 2x + 8 = 56
4x = 56 - 8
x = 48/4
x = 12
Answer:
Lucy had 40 books last year.
Step-by-step explanation:
assuming 100% is the percent;
100% + 70%
100 : x
170 : 68
cross multiply = 170x = 100 x 68
-------- ————-
170 170
cancel 170/170
therefore x = 100 x 68 divided by 170
result is 40
