Using a midpoint Riemann sum with 3 subintervals of equal length to approximate
is 2020 and
means the distance in feet, traveled by rocket A from t=0 seconds to t=70 seconds.
From the given question,
An initial height of 0 feet at time t=0 seconds.
The velocity of the rocket is recorded for selected values of over the interval 0 < t < 80 seconds.
(a) Using a midpoint Riemann sum with 3 subintervals of equal length to approximate

![\int^{70}_{10}v(t)dt](https://tex.z-dn.net/?f=%5Cint%5E%7B70%7D_%7B10%7Dv%28t%29dt)
A midpoint Riemann sum with 3 sub intervals so, n=3
∆t= (70-10)/3
∆t = 60/3
∆t = 20
Intervals: (10, 30), (30,50), (50,70)
Midpoint: 20 40 60
Midpoint Riemann Sum
= ∆t[v(20+v(40)+v(60)]
From the table
= 20[22+35+44]
= 20*101
= 2020
(b) Now we have to explain the meaning of v(t)dt in terms of the rocket's flight
.
It means the distance in feet, traveled by rocket A from t=0 seconds to t=70 seconds.

-24+m=-47
First, you add 24 to -47. Then you find that m=-23. To check your work, plug -23 in the equation for m, and solve.
Answer:
A
Step-by-step explanation:
The formula for the perimeter is 2l +2w. 4x^2+4x^2=8x^2. y^2+y^2=2y^2.
If we add them together the answer is 8x^2+2y^2.
Hi do you mind showing your on the side or something thank you
