use the trapezoidal rule, the midpoint rule, and simpson's rule to approximate the given integral with the specified value of n. (round your answers to six decimal places.) 4 0 ln(3 ex) dx, n

Answers

Answer 1

a. Trapezoidal Rule- 9.413607

b. Midpoint Rule-9.393861

c. Simpson's Rule -9.400407

a. We use n=8 for this integral, .Δt=4-0/8=0.5

Therefore the integral range is[0,0.5,1.0,1.5......3.0,3.5....4.0 ]

#For the Trapezoidal Rule:

[tex]\int\limits^a_b[/tex]∫(x)dx≈[tex]Tn=[/tex]Δr/2[∫([tex]x0[/tex])+2∫(x1)+....+∫(xn)]

=[tex]\int\limits^4_0[/tex][tex]In(2+ex[/tex])dx≈[tex]T8[/tex]

=0.5/2[[tex]In[/tex](2+[tex]e0.0[/tex])+2In(2+e0.5)+2In(2+e1.0)+....+2In(2+e3.5)+In(2+e4.0)]

=0.25[1.098612+2.588754+3.102889+3.737962+4.479090+5.304017+6.189846+7.117283+4.035976]

≈9.413607

Hence, the approximate integral value using Trapezoidal rule is 9.413607

b.For the Midpoint Rule, we calculate the integral as:

[tex]\int\limits^a_b[/tex]∫(x)dx≈[tex]Mn=[/tex]Δx[∫[tex](x1)[/tex]+∫([tex]x2)[/tex]........∫([tex]xn)}[/tex]

x1 is the midpoint of the ith interval.

From our interval ,[0,0.5,1.0,1.5....3.0,3.5,4.0]the applicable intervals are

[0.25,0.75,1.25,2.25,2.75,3.25,3.75]

We therefore have the integral value as:

=4/8[[tex]In[/tex](2+[tex]e0.25[/tex])+In(2+[tex]e0.72[/tex])+In(2+[tex]e1.25[/tex])+....+In(2+[tex]e1.75[/tex])+In(2+[tex]e2.25[/tex])[tex]In[/tex](2.75)+In(2+e0.5)+In(2+e1.0)]

Hence, the approximate integral value using the Midpoint Rule is 9.393861

c. For the Simpson's Rule, we calculate the integral rule as follows:

Hence, the approximate integral value using the Simpson's Rule is 9.400407

The distance between two places along a segment of a curve is known as the arc length.

What is arc length of a circle?

The distance between two places along a segment of a curve is known as the arc length. Curve rectification is the process of measuring the length of an irregular arc section by simulating it with connected line segments.

There are a finite number of segments in the rectification of a rectifiable curve. Using the arc length formula, one may determine a circle's arc length given its radius and center angle. Arc length is equal to r, where r is the radian unit. Arc length is equal to (r/180), where r is the radius in degrees.,

Given :[tex]$r=1, \theta=5 \pi / 6$[/tex]

Now, arc length

[tex]&=\theta / 2 \pi * 2 \pi r \\[/tex]

Find the area of a circle

Answers

Answer: 452 cm squared

Step-by-step explanation:

Since the diameter is the radius times two, the radius of this circle is 24 divided by 2 which is 12. To find the area of a circle you multiply the radius by pi. Pi= 3.14, so 3.14(pi) times 12(radius)= 452.16 cm.

Stella walks down a flight of stairs to the basement. Then she walks back up the stairs and another flight of stairs to the second floor of her house. Each flight of stairs represents a change of 12 feet in height. How far is Stella above the ground

Answers

If Stella walks down a flight of stairs to the basement. Then she walks back up the stairs and another flight of stairs to the second floor of her house. How far is Stella above the ground is: 12 ft.

Height above the ground

Given:

Flight stair = 12 feet

Hence,

Let walking from down a flight of stairs to the basement = -12 f

Let  walking back up the stairs = 12Ft

Now let determine Stella height above the ground.

Height = -12 feet + 12 feet + 12 feet

Height = 12 feet

Therefore we can conclude that Stella is 12 feet above the ground.

Answers

Answer:
y= [tex]-\frac{4}{3}x-\frac{7}{3}[/tex], so [tex]-\frac{4}{3}[/tex] is your slope!

Step-by-step explanation:

It's best to get this equation in slope-intercept form, meaning to solve for y.

My work is shown below, as to how I solve for y.

4x + 3y = -7

3y = -7 - 4x

Afterward, divide the other side by 3.

y = (-4/3)x (-7/3)

That's how you get the answer. Hope this helped.

As, y = mx + b, and the m stands for the slope, -4/3 is your slope.

the slope is -4/3
Move the X to the other side to leave y by itself. you’re left with 3y=-4x-7, divide by 3 in order to once again,leave the y by itself, youre left with y=-4/3x-7/3 but since you want the slope, it is the number next to the x

Part 1
Point B has coordinates ​(5​,1​). The​ x-coordinate of point A is −3. The distance between point A and point B is 10 units. What are the possible coordinates of point​ A?

Answers

The possible coordinates of the point​ A is (-3, -5) and  (-3, 7)

How the coordinates of point​ A can be calculated?

The given parameters are:

Point B = (5, 1)Distance between the two points, D = 10 unitsx-coordinate of point A = −3

This means that

A = (-3, y)

The distance between any two points is calculated as

D = √[(x₁ - x₂)² + (y₁ - y₂)²]

Substitute the known values in the above equation

So, we have

10 = √[(-3 - 5)² + (y - 1)²]

Evaluate the difference

10 = √[(-8)² + (y - 1)²]

Take the square of both sides

100 = (-8)² + (y - 1)²

So, we have

100 = 64 + (y - 1)²

Evaluate the like terms

(y - 1)² = 36

Take the square roots

y - 1 = ±6

This gives

y = 1 ± 6

So, we have

y = -5 and 7

Hence, the coordinates of point​ A is (-3, -5) and  (-3, 7)

Which expression is equivalent to ​8(x+3)−14(20x−56)​

Answers

8(101 -34x) is the equivalent expression of 8(x+3)−14(20x−56)​

What is the equivalent expression?

Equivalent expressions can be defined as expressions that are the same, even though they may look a little different. If you plug in the same variable value into equivalent expressions, they will each give you the same value when you simplify

Given 8(x+3)−14(20x−56)​

By eliminating the parenthesis:

8(x+3)−14(20x−56)​ = ( 8(x) + 8(3) ) - ( 14(20x) - 14(56) )

                            = 8x + 24 - 280x + 784         Add/Subract like terms

                           = -272x + 808

                           = 8(-34x + 101)

                           = 8 (101 -34x)

Therefore the equivalent expression for 8(x+3)−14(20x−56)​ is 8(101 -34x)

Selecting the number of bins is an important decision when working with histograms. Are there any rules or recommendations for choosing the number or width of bins? what happens if we use too many or too few bins?.

Answers

When working with Histograms, choose from 5 to 20 bins. The greater the data collection, the more probable it is that you will require a high number of bins. For example, a collection of 12 data points may deserve 5 bins, whereas a set of 1000 numbers will most likely benefit from 20 bins. The exact number of bins is typically a matter of personal preference.

Answers

Using the binomial distribution, there is a 0.6328 = 63.28% probability that she wins at most 1 prize.

For each box, there are only two possible outcomes, either it has a prize, or it does not. The probability of a box having a prize is independent of any other box, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

In this problem:

She buys 5 boxes, hence

1 in 4 boxes has a prize, hence

The probability is:

P ( X ≤ 1 ) =P ( X = 0 ) + P ( X = 1 )

Then ,

P ( X ≤ 1 ) = P ( X = 0 ) + P ( X = 1 )

= 0.2373 + 0.3955
