Answer:

Step-by-step explanation:

1/5 of 10 is 2,

so if you have 3/5, it is the same as 1/5 3 times.

1/5 of 10 is 2, so for 3/5 of 10 you multiply 2 by 3.

1/5 of 10 = 2

2/5 of 10 = 4

3/5 of 10 = 6

4/5 of 10 = 8

5/5 of 10 = 10

Answer:

One fifth is like you saying one fifth of something, so if you have 3 fifths of something it's just 3 times more than one fifth. so like 1/5 is 20% so 3/5 is 3 times more which is 60%

Answer:

$179.20

Step-by-step explanation:

use the formula retail price = original price + markup

Step One: Convert 28% to a decimal

--> 0.28

Step two: Plug all the numbers into the equation

--> $140 + $140 x 0.28 = $179.20

Let f(x)=x^2f ( x ) = x 2. Find the Riemann sum for ff on the interval [0,2][ 0 , 2 ], using 4 subintervals of equal width and t

sladkih [1.3K]

Answer:

$A_L=1.75$

Step-by-step explanation:

We are given:

$f(x)=x^2$

$interval = [a,b] = [0,2]$

Since $n = 4$ ⇒ $\Delta x = \frac{b-a}{n} = \frac{2-0}{4}=\frac{1}{2}$

Riemann sum is area under the function given. And it is asked to find Riemann sum for the left endpoint.

$A_L= \sum\limits^{n}_{i=1}\Delta xf(x_i) = \frac{1}{2}(0^2+(\frac{1}{2})^2+1^2+(\frac{3}{2})^2)=\frac{7}{4}=1.75$

Note:

If it will be asked to find right endpoint too,

$A_R=\sum\limits^{n}_{i=1}\Delta xf(x_i) =\frac{1}{2}((\frac{1}{2})^2+1^2+(\frac{3}{2})^2+2^2)=\frac{15}{4}=3.75$

The average of left and right endpoint Riemann sums will give approximate result of the area under $f(x)=x^2$ and it can be compared with the result of integral of the same function in the interval given.

So, $(A_R+A_L)/2 = (1.75+3.75)/2=2.25$

$\int^2_0x^2dx=x^3/3|^2_0=8/3=2.67$

Result are close but not same, since one is approximate and one is exact; however, by increasing sample rates (subintervals), closer result to the exact value can be found.
