OMG im suffering in this too
but im starting to get this so lets take a look
i tried writing an equation but all i get is one so
answer is one and slope is 0 hope i could help
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:
y=3x^2,y=5^2,y=7x^2
Step-by-step explanation:
y=3x^2 is the widest, y=7x^2 is the narrowest, which leaves y=5x^2 in the middle
Answer:
2520ft
Step-by-step explanation:
Calculation for what is the scale of the model?
Let x will be the span length
Hence,
x= 4200 feet long/20 inches long
x=210
Thus:
1 inch = 210 ft
1 ft = 2520
=2520ft
Therefore the scale of the model will be 2520ft
Answer: 186 miles
Step-by-step explanation: 1. 182.81-20.99=161.82 2. 161.82/0.87=186
