Recall that Rn denotes the right-endpoint approximation using n rectangles, Ln denotes the left-endpoint approximation using n r
pogonyaev

Answer:

R_5=1.12

Step-by-step explanation:

We want to calculate the right-endpoint approximation (the right Riemann sum) for the function:

f(x)=x^2+x

On the interval [-1, 1] using five equal rectangles.

Find the width of each rectangle:

\displaystyle \Delta x=\frac{1-(-1)}{5}=\frac{2}{5}

List the <em>x-</em>coordinates starting with -1 and ending with 1 with increments of 2/5:

-1, -3/5, -1/5, 1/5, 3/5, 1.

Since we are find the right-hand approximation, we use the five coordinates on the right.

Evaluate the function for each value. This is shown in the table below.

Each area of each rectangle is its area (the <em>y-</em>value) times its width, which is a constant 2/5. Hence, the approximation for the area under the curve of the function <em>f(x)</em> over the interval [-1, 1] using five equal rectangles is:

\displaystyle R_5=\frac{2}{5}\left(-0.24+-0.16+0.24+0.96+2)= 1.12

A recipe for chili calls for 4/5 cup of water. You are making 1/3of the recipe. How much water do you use?
mrs_skeptik [129]
Sense, the recipe would then have to be using as a whole of 4/5 of water, we would then, have to divide 4/5 by 1/3, and by us doing this, we would then get our answer as the following:

\boxed{\boxed{ \frac{4}{5}\div \frac{1}{3}=  5/12}}

ziro4ka [17]

Total surface area of cylinder :

[(22/7)(7)²] × 2 ( area for 2 circles )

+

[ 2(22/7)(7) ] ×12 ( circumference of circle × height )

=

836 cm²

i hope my solution helps :))
