Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).

Answers

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.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

-What is the y-intercept of the line of best fit?
-What is the slope of the line of best fit for this scatter plot?
-What is the equation of the line of best fit?

-What is the y-intercept of the line of best fit?-What is the slope of the line of best fit for this

Answers

Answer:

y-intercept : 8

slope: -1/2

equation:   \(y = -\dfrac{1}{2}x + 8\)

Step-by-step explanation:

The y-intercept is where the line crosses the y axis and you can see it crosses at y = 8 (when x =0)

Slope of the line can be found by the formula (y2-y1) / (x2-x1)  where 9x1, y1) and (x2, y2) are two points on the line

Let's take the points (0, 8) and (10, 3) the two extreme points on the line

Slope = (3 - 8) / (10 - 0) = -5 / 10 = - 1/2

Equation of a line in slope intercept form is

y = mx + c

where m is the slope  

b is the y intercept

The equation of the line is therefore

\(y = -\dfrac{1}{2}x + 8\)

Answer:

Y-intercept = 8

Slope = -1/2t

Equation = y =-1/2x+8

Step-by-step explanation:

When x = 0, y = y-intercept.

Therefore, the y-intercept is 8.

We can find the slope using the formula y2-y1 / x2-x1 = m.

Let's use the points (0,8) and (4,6)

6-8 / 4-0 = m;

m = - 1/2.

Given that the generic formula is y=mx+b, and m-slop and b=y-intercept, we have:

y = -1/2x+8.

-1/3, -1/5, 0, 1/8
u put the negative numbers to the left and positive ones to the right then since -1/3 is more negative than -1/5, -1/3 goes to the left and-1/5 goes next to it and then 0 and since 1/8 is the biggest it goes to the right
Since it’s negative the negative is the least but there two of them so you have to convert them to decimales
1/3 = .333333 and 1/5 is .2
So 1/3 goes first then 1/5
1/8 is .125 it’s larger than 0

At which values of x does the function F(x) have a vertical asymptote? Check
all that apply,
F(x)
9
(x - 1)(x-8)

Answers

Answer:

The values of x that makes f(x) have a valid asymptote are 1 and 8

Step-by-step explanation:

Given

\(f(x) = \frac{9}{(x-1)(x-8)}\)

Required

At what value does f(x) has a vertical asymptote

To solve this, we simply equate the denominator of f(x) to 0;

This is done as follows

\({(x-1)(x-8)} = 0\)

This can be split to

\({(x-1) = 0 \ or\ (x-8)} = 0\)

Remove brackets

\(x-1 = 0 \ or\ x-8 = 0\)

Make x the subject of formula in both cases

\(x-1+1 = 0+1 \ or\ x-8+8 = 0+8\)

\(x= 0+1 \ or\ x = 0+8\)

\(x= 1 \ or\ x = 8\)

The values of x that makes f(x) have a valid asymptote are 1 and 8
