The expression of integral as a limit of Riemann sums of given integral is 4 ∑ from i=1 to i=n.
Given an integral .
We are required to express the integral as a limit of Riemann sums.
An integral basically assigns numbers to functions in a way that describes displacement, area, volume, and other concepts that arise by combining infinite data.
A Riemann sum is basically a certain kind of approximation of an integral by a finite sum.
Using Riemann sums, we have :
=∑f(a+iΔx)Δx ,here Δx=(b-a)/n
=f(x)=
⇒Δx=(5-1)/n=4/n
f(a+iΔx)=f(1+4i/n)
f(1+4i/n)=
∑f(a+iΔx)Δx=
∑
=4∑
Hence the expression of integral as a limit of Riemann sums of given integral is 4 ∑ from i=1 to i=n.

Answer:
Where is your attachment ?
Answer:
B) 9.2
Step-by-step explanation:
To find an average, you have to combine all of your numbers and then divide by how many there are.
So first, combine the values.
9.7 + 8.6 + 9.3 = 27.6
Now, divide by how many numbers you had, which is 3.
27.6 ÷ 3 = 9.2
