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.

e equal

f less

g equal

Answers in bold:

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

Explanation:

We have these three rules for scale factors

With those rules in mind, we have enlargements for these transformations.

All of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.

In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.

----------------

We also have these reductions

This is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.

----------------

And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.

The order doesn't matter for this subset, but the order will matter for the other batches of transformations.

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Answer: y= 21x

Step-by-step explanation:

As you can see, the line is steadily increasing. To make an equation for the line, we need to use the formula y=mx+b.

Step 1: Find the slope, "m"

m is the slope of the line, calculated by finding 2 points on the line, and using the formula rise÷run.

To do this, find a point on the line. (Make sure it's an actual point, not one that is in between the lines). In this example I will use 0,0. Then, find the nearest (actual) point on the line. That will be 1,21.

Now, we will use rise/run.

To get from the 2 points I listed, we must rise, or go up, 21. Then, we must "run", or go left or right 1. In this case we go left.

Therefore, the "rise"= 21, and the "run"= 1. Now 21÷1= 21, so the slope is 21.

Step 2: Find the y-intercept, "b"

b is the y intercept of the line, whch is the first point on the y axis that the line is on. In this line, the y intercept is 0.

Step 3: Write the equation

Now that we know what "m" and "b" stand for, we can replace these letters with the numbers by plugging in.

y=mx+b

y= 21x+0

y= 21x

*Note that when the y intercept ("b") is 0, you don't write it in the equation, but if it were a number other than 0, you would.

Hope this helps :)

Answer:

525

Step-by-step explanation:

If it's just asking to find the average of heads then times it by 20 then just do 32+28+21+24 to get 105 and divide it by 4 to get 26.25 then times it by 20 since this is the average of 50 throws and it's asking for the average of 1,000 throws which is 525

Answer:

The answer is D.

Step-by-step explanation:

y = mx + b

C = 5/9 (F - 32)

C = 5/9F - 5/9 (32)

Option (D) is correct.

Answer: the rate of change is 1/2

Step-by-step explanation:

The formula for slope is y2 - y1/ x2 - x1

I picked points (2,2) (x1 & y1) and (6,4) (x2 & y2)

4 - 2 = 2

6 - 2 = 4

2/4 is the rate of change, and 1/2 is 2/4 simplified

A. The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.

C. The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.

E. The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.

In Mathematics and Statistics, the mean for any set of data can be calculated by using the following formula:

Mean, \bar{x} = ∑x/n

Where:

Based on the information provided, we have:

Mean of Yard Works = (7+9+7+12+5)/5

Mean of Yard Works = 8.

Mean of Grow Station = (9+11+6+12+7)/5

Mean of Grow Station = 9.

Range is the difference between the maximum and minimum numbers;

Range of Yard Works = 12 - 5

Range of Yard Works = 7.

Range of Grow Station = 12 - 6

Range of Grow Station = 6.

Mean absolute deviation is given by;

MAD = 1/n ∑|x - μ|

Where:

Mean absolute deviation of Yard Works = 2

Mean absolute deviation of Grow Station = 2.

In a box plot, also known as a box-and-whisker plot, the data is dispersed and represented visually to provide a summary of the distribution and key characteristics of the dataset. Let's describe how the data is dispersed in the box plot for the given data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.

By observing the box plot, we can see that the data is moderately dispersed, with the majority of values concentrated around the median. The range of the data is approximately 20 to 38, with some variability within the dataset.

Pierce ran/walked 7/4 or (1 3/4) miles more on wednesday than on tuesday

Step-by-step explanation:

so on tuesday he ran :

3/4 + 3/4 miles which = 6/4 miles

on wednesday he ran and walked:

2/4 + 11/4 = 13/4 miles

Answer:

To find the discounted price of the portable CD player, we need to multiply the original price by the discount rate and then subtract that amount from the original price.

Discount = 30% of $59.95

Discount = 0.3 x $59.95

Discount = $17.985

Discounted Price = Original Price - Discount

Discounted Price = $59.95 - $17.985

Discounted Price = $41.965

Therefore, the discounted price of the portable CD player is $41.97 to the nearest cent.

Step-by-step explanation:

Pls give brainlist!

Answer:

$41.96

Step-by-step explanation:

To find the discounted price of the CD player, we can start by calculating the amount of the discount.

Discount = 30% of $59.95

Discount = 0.30 x $59.95

Discount = $17.985 or $17.99 (rounded to the nearest cent)

The discounted price of the CD player is the original price minus the discount:

Discounted price = $59.95 - $17.99

Discounted price = $41.96 (rounded to the nearest cent)

Therefore, the discounted price of the portable CD player is $41.96 to the nearest cent.
