Answer:
46.375
Step-by-step explanation:
Given information:

where, 0 ≤ x ≤ 3.
We need to divde the interval [0,3] in 6 equal parts.
The length of each sub interval is

Right end points are 0.5, 1, 1.5, 2, 2.5, 3.
The value function on each right end point are






Riemann sum:

![Sum=[f(0.5)+f(1)+f(1.5)+f(2)+f(2.5)+f(3)]\times 0.5](https://tex.z-dn.net/?f=Sum%3D%5Bf%280.5%29%2Bf%281%29%2Bf%281.5%29%2Bf%282%29%2Bf%282.5%29%2Bf%283%29%5D%5Ctimes%200.5)
![Sum=[0.25+3+8.25+16+26.25+39]\times 0.5](https://tex.z-dn.net/?f=Sum%3D%5B0.25%2B3%2B8.25%2B16%2B26.25%2B39%5D%5Ctimes%200.5)


Therefore, the Riemann sum with n = 6 is 46.375.
Answer:
See below
Step-by-step explanation:
I think it’s four less than the quotient of a number cubed and seven, increased by three
I hope you get this right!
Answer: 8.125 square inches
Explanation/Calculation:
First, convert the fractions to decimals.
3 1/4= 3.25
2 1/2= 2.5
Now multiply 3.25*2.5
You get 8.125
Answer:
AB = 21
Step-by-step explanation:
So we have two triangles (AEB and ADC), and they're similar by AA
Now, you can find the ratio of similitude by checking AE/AD which is 14/26 = 7/13
AB/AC = 7/13
Take AB as x aight
x/x+18 = 7/13
x=21
