Answer:

123

Step-by-step explanation:

First arrange in ascending or descending order

110,123,123,145,256

Then pick the number in the middle which is 123

but if you have 2 middle numbers add them together and divide by 2

If f(x) = 5x2 − 2x, 0 ≤ x ≤ 3, evaluate the Riemann sum with n = 6, taking the sample points to be right endpoints. R6 =
Leona [35]

Answer:

46.375

Step-by-step explanation:

Given information:

f(x)=5x^2-2x

where, 0 ≤ x ≤ 3.

We need to divde the interval [0,3] in 6 equal parts.

The length of each sub interval is

\dfrac{b-a}{n}=\dfrac{3-0}{6}=0.5

Right end points are 0.5, 1, 1.5, 2, 2.5, 3.

The value function on each right end point are

f(0.5)=5(0.5)^2-2(0.5)=0.25

f(1)=5(1)^2-2(1)=3

f(1.5)=5(1.5)^2-2(1.5)=8.25

f(2)=5(2)^2-2(2)=16

f(2.5)=5(2.5)^2-2(2.5)=26.25

f(3)=5(3)^2-2(3)=39

Riemann sum:

\sum_{n=1}^6 f(x_n)\Delta x_n

Sum=[f(0.5)+f(1)+f(1.5)+f(2)+f(2.5)+f(3)]\times 0.5

Sum=[0.25+3+8.25+16+26.25+39]\times 0.5

Sum=92.75\times 0.5

Sum=46.375

Therefore, the Riemann sum with n = 6 is 46.375.

I need help with this
Stells [14]

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
