To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Answer: x divided by y= 0.25

Step-by-step explanation:

================================

Work Shown:

4  1/2 = 4 + 1/2 = 4 + 0.5 = 4.5

In short, 4  1/2 cups is the same as 4.5 cups

---------

1 cup = 8 fluid ounces

4.5*(1 cup) = 4.5*(8 fluid ounces) .......  multiply both sides by 4.5

4.5 cups = 36 fluid ounces

Answer:

D

Step-by-step explanation:

Answer:

b)

Step-by-step explanation:

Supplementary angles add up to 180 degrees, so the answer must be b).  Let's check the math:

77 + (5x + 18) = 180

-77                    -77

(5x + 18) = 103  --> here we already know this is correct, as the problem tells us that angle H is equal to this equation, (5x + 18), and we know that it is also equal to 103.

Answer:

d= m/v

so it's B. Divided

Answer:

-13.5

Step-by-step explanation:

Answer:

-13.5

Step-by-step explanation:

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

Domain is all real numbers. Range is

Step-by-step explanation:

The function  is a transformation of the parent function  by moving the function up by 3 units.

So, the graph of the function is shown below.

From the graph, it is clear that the  values has no limitation and hence can take any real values. Domain is the set of all possible  values.

So, domain is the set of all real numbers.

Range is the set of all possible values for  for the given domain.

From the graph, the minimum value of  is at the point (. So, the minimum value of y is 3. The  value then goes on increasing towards infinity.

Therefore, range is a real number greater than or equal to 3.

So, range is  or  

The slope-intercept form is y =  -3 x - 2  and y-intercept is  -2.

The  slope-intercept form is equation of the line.  i.e;

     y = m x  + c

 where m is the slope of the line.

   and  c is the y-intercept.

Given,

The equation of the line

   12 x =  -4 y - 8

   - 4 y = 12 x + 8

Multiplying both sides by -1

     4 y =  - 12 x - 8

Dividing  both sides by 4

        y =  -3 x + -2

where  -3  is the slope of the line.

So,The slope-intercept form is y =  -3 x - 2 and y-intercept is  -2.

Simplify.

2 ( 4 x + 1 )

Step-by-step explanation:

I think thats the answer if it is can you please mark brainliest:)

The factor after the expression by using GCF is 2(4x + 2).

The greatest common factor is the largest positive number which can be divided into given numbers evenly.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The given expression is 8x+2. The factor of the expression by the GCF will be calculated as,

F = 8x + 2

F = 2 (4x + 1)

Therefore, the factor after the expression by using GCF is 2(4x + 2).

Answer:

223

Step-by-step explanation:

Answer:

H. 95°

Step-by-step explanation:

m∠BGC is 10° smaller than m∠CGD, which means that m∠BGC is x° - 10°

m∠DGE is 25° more than m∠EGF, which means that m∠DGE is x° + 25°

The sum of all angles in a placement like this will always equal 360°

So we put all the measures of all angles on one side of thee equation and set it equal to 360*

x° + x° - 10° + 2x° + 25° + 2x° + 3x° + 30° = 360°

After combining like terms we get 9x° + 45° = 360°

After some algebra we get x = 35°

Now at the start we said that m∠DGE is x + 25°

Plug in 35° for x and we get 35° + 25°

The final answer is m∠DGE = 95°
