Set Up But Do Not Evaluate An Integral For The Length Of X^2/16. (2024)

Mathematics High School

Answers

Answer 1

Answer:

[tex]L=\int\limits^b_a {\sqrt{1+\frac{x^2}{64}}} \, dx[/tex]

Step-by-step explanation:

Recall the formula for the arc length of a function given a closed interval [tex][a,b][/tex]: [tex]L=\int\limits^b_a {\sqrt{1+(\frac{dy}{dx})^2}} \, dx[/tex]

Given the function [tex]y=\frac{x^2}{16}[/tex], then [tex]\frac{dy}{dx}=\frac{x}{8}[/tex] by the product rule.

Thus, the set-up integral would be:

[tex]L=\int\limits^b_a {\sqrt{1+(\frac{x}{8})^2} } \, dx\\ \\L=\int\limits^b_a {\sqrt{1+\frac{x^2}{64}}} \, dx[/tex]

Answer: It's not a function because the line is curved, and it has an exponent in the equation which makes the line curved instead of straight which will make x repeat.

Someone please help me answer Number 14, PLEASE!

Answers

Answer:

b=240

Step-by-step explanation:

We need to find b. In order to this, we must isolate b.

[tex]-17+\frac{b}{8}=13[/tex]

Add 17 to both sides

[tex]\frac{b}{8}=30[/tex]

Multiply both sides by 8 to remove the fraction

[tex]b=240[/tex]

Answer:

b = 240

Step-by-step Solution:

-17 + b/8 = 13=> b/8 = 13 + 17=> b/8 = 30=> 8 x b/8 = 30 x 8=> b = 240

Hence, the value of b is 240.

Answer:

3 = 10.50

7 = 24.5

10 = 35.00

Step-by-step explanation:

If this is wrong I am sorry.

Hope this helps

Step-by-step explanation:

This is it. Proportion

if 3 pounds of blue berries cost 10.50

1 pound of blue berries cost 10.50÷3=3.50

Therefore 7 pounds of blue berries cost

3.50 ×7= 24.50

2. Let a be the number of pounds of blue berries you can buy with 35.00

1 = 3.50

a = 35.00

a=35.00÷3.50

a= 10

Therefore, 35.00 is equal to 10 pounds of blue berries.

use the leading coefficient and the degree of the polynomial function to determine the end behavior of the graph. f(x) = 3x^2 - 3x^5 - 14x - 2x^3 - 5
leading coefficient:
degree:
end behavior left or right side:

Answers

Answer:

end behavior on left: function goes to + infinity

end behavior on the right: function goes to - infinity

Step-by-step explanation:

You look at the highest powered x term.

You look at the highest powered x-term which is - 3x^5. The polynomial will begin and end the same way a -x^5 curve begins and ends.

end behavior on the left side (as x approaches negative infinity), y values approach positive infinity. You can substitute negative values of x (-1, -5, -10, -100 . . .) in - 3x^5 and you will get increasing positive values for y as you use x values that approach negative infinity).

end behavior on the right side (as x approaches positive infinity), y values approach negative infinity. Substitute positive values for x (1, 10, 100, 1,000 . . .) in - 3x^5 and you will get decreasing negative values for y.

What is the length of in the figure below?

Select one:

20.8 units

8 units

12 units

14.4 units

Answers

Answer:

Third option

Step-by-step explanation:

Given the following question:

Side c = 24 units

Angle B = 30 degrees
Angle C = 60 degrees
30 + 60 = 90
90 + 90 = 180
(all angles add up to 180 degrees)
Angle A = 90 degrees

Apply the law of sines:

[tex]a=c\times sin(a)[/tex]
[tex]a=24\times sin(60)=20.7846097[/tex]
[tex]20.7846097[/tex]
[tex]8 > 5[/tex]
[tex]20.8[/tex]

Now we have all the angles and two of the sides:

A = 20.8
C = 24

[tex]b=c\times sin(b)[/tex]
[tex]b=24\times sin(30)=12[/tex]
B = 12 units

Angle A - 90 degrees
Angle B - 30 degrees
Angle C - 60 degrees

Side AC - 12 units
Side BC - 24 units
Side BA - 20.8 units

Hope this helps.

Statement:

Two angles are supplementary. One angle measures 2x, and the other angle measures 3x - 15.

To find out:

The equation to find the measure of each angle.

Solution:

Supplementary angles are angles which sum up to 180°.While, complementary angles are angles which sum up to 90°.Here, the sum of the two angles, i.e., 2x and 3x - 15, should be 180°.So, the equation will be: 2x + 3x - 15 = 180°.

Answer:

2x + 3x - 15 = 180°

17% of what number is 3.4

Answers

Answer:

20

Step-by-step explanation:

We already have our first value 3.4 and the second value 17. Let's assume the unknown value is Y which answer we will find out.

As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

Step 1 ---> 3.4 = 17% × Y

Step 2 ---> 3.4 = 17/100 × Y

Multiplying both sides by 100 and dividing both sides of the equation by 17 we will arrive at:

Step 3 ---> Y = 3.4 × 100/17

Step 4 ---> Y = 3.4 × 100 ÷ 17

Step 5 ---> Y = 20

Finally, we have found the value of Y which is 20 and that is our answer.

*You can easily calculate 3.4 is 17 percent of what number by using any regular calculator, simply enter 3.4 × 100 ÷ 17 and you will get your answer which is 20*

Segment VY is a midsegment of trapezoid FEDC. Find x.

Answers

Answer:

x = 12

Step-by-step explanation:

The midsegment VY is half the sum of the parallel bases , that is

VY = [tex]\frac{EF+CD}{2}[/tex] , then

3x + 18 = [tex]\frac{1}{2}[/tex] (x + 96) ← multiply both sides by 2 to clear the fraction

6x + 36 = x + 96 ( subtract x from both sides )

5x + 36 = 96 ( subtract 36 from both sides )

5x = 60 ( divide both sides by 5 )

x = 12

We observe that the function is non-linear from x = 0 to x = 2.5

Therefore, the interval for which the function is non-linear is given by:

Consider two unquie parallel lines what aspects of these two lines are the same ? What aspect of the two lines would have to be different explain your reasoning

Answers

Answer:

The aspect of the lines that are the same is that they have the same slope while the aspect of the lines that are different is that they have different x and y-intercepts

Parallel lines are lines that do not meet in a xy-plane

If the parallel lines are vertical lines, they will both cut the x-axis at different points showing that they will have different x-intercept.

Similarly, if the parallel lines are horizontal lines, they will both cut the y-axis at different points showing that they will have different y-intercept.

Parallel lines are also known to have the same slope. This is the aspect that is common to both lines.

FAQs

How do you find the length of a curve with integrals? ›

To summarize, to compute the length of a curve on the interval [a,b], we compute the integral ∫ba√1+(f′(x))2dx. Unfortunately, integrals of this form are typically difficult or impossible to compute exactly, because usually none of our methods for finding antiderivatives will work.

How do you evaluate the arc length of an integral? ›

The arc length s can be recovered by integrating the differential, s = ∫ ds. Intuition: We can approximate the length of a curve with a polygonal path of line segments of the form ∆si = √(∆x)2 + (∆yi)2. i ))2∆x. √1+(f (x))2 dx.

How to calculate the length of a curved line? ›

The arc length of a curve can be calculated using a definite integral. The arc length is first approximated using line segments, which generates a Riemann sum. Taking a limit then gives us the definite integral formula. The same process can be applied to functions of y.

How to find the exact length of a curve? ›

For the given curve, We will use the formula for the length of the arc(L) of the graph. For finding arc length (L), we will use the following formula, L = ∫ba ∫ a b √[1 + (dy/dx)2] dx.

What is the formula for the line length integral? ›

We are now ready to state the theorem that shows us how to compute a line integral. ∫Cf(x,y)ds=∫baf(x(t),y(t),z(t)) √(x′(t))2+(y′(t))2+(z′(t)2)dt.

What is the arc length method? ›

The arc-length method is the most powerful path following method in the solution of equilibrium paths, bifurcation points and limit points by introducing a constraint condition which establishes the nonlinear equations in which the unknown load parameter is determined.

How to calculate the length of an arc? ›

Arc length = (θ/360) of 2πr = (θ/360) × 2πr = rθ × π/180. This formula represents the arc length when the angle is measured in degrees. The length of an arc can be determined using different formulas, depending on the unit used to measure the central angle.

How to find the distance of a curve? ›

In a way, the distance formula for parametric equations lets you measure the curve with a continuous chain of infinitely small triangles. The equation for the length of a curve in parametric form is: L = ∫ a b ( x ′ ( t ) ) 2 + ( y ′ ( t ) ) 2 d t .
