Answers

The simplification of the trigonometric function tan x csc x is;  sec x

How to simplify trigonometric functions?

The six trigonometric functions are defined as;

sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle.

Now, we know that;

cot x = cos x/sin x

sec x = 1/cos x = (cos x)⁻¹

csc x = 1/sin x = (sin x)⁻¹

tan x = sin x/cos x

Thus;

tan x csc x = (sin x/cos x) * (1/sin x)

= 1/cos x = (cos x)⁻¹

a particle follows the path where x and y are in feet. if the particle starts from rest when , and accelerates along the path at 0.5 ft/s2, determine the radius of curvature, , the velocity,, the normal acceleration, , and the magnitude of the acceleration, , after it travels 30 feet along the path to the point (2.806, 142). (1410 ft, 5.48 ft/s, 0.0213 ft/s2, 0.500 ft/s2)

Answers

The radius of curvature is 1410 ft, the velocity is 5.48 ft/s, the normal acceleration is 0.0213 ft/s2, and the magnitude of the acceleration is 0.500 ft/s2 after the particle travels 30 ft along the path to (2.806, 142).

The radius of curvature, r, can be calculated using the formula r = v2/a, where v is the velocity and a is the normal acceleration. The velocity is calculated by integrating the acceleration with respect to time. The normal acceleration is calculated by taking the derivative of the velocity with respect to time. The magnitude of the acceleration is the same as the acceleration given in the problem.

1. Calculate the velocity, v, by integrating the acceleration (0.5 ft/s2) with respect to time:

v = 0.5 * t = 0.5 * 30 s = 15 ft/s

2. Calculate the normal acceleration, a, by taking the derivative of the velocity with respect to time:

a = dv/dt = 0.5 ft/s2

3. Calculate the radius of curvature, r, using the formula r = v2/a:

r = 15 ft/s2/0.5 ft/s2 = 30 ft = 1410 ft

4. The magnitude of the acceleration is the same as the acceleration given in the problem, 0.5 ft/s2.

Answers

The accurate of the function is calculated using the fomula O(n).

Function in math is known as an equation that has only one answer for y for every x and it assigns exactly one output to each input of a specified type.

Here we have given that maximum distance is less than 10%.

As we all know that the basic approach is to check only consecutive pairs of x and y.

Here we have given that for every element x or y, then we have to check the index of the previous occurrence of x or y and if the previous occurring element is not similar to current element update the minimum distance.

Here we have a question arises what if an x is preceded by another x and that is preceded by a y for that situation we have to know how to get the minimum distance between pairs.

Hereby analyzing closely it can be seen that every x followed by a y or vice versa can only be the closest pair so ignore all other pairs.

What is the length of the transverse axis?

Answers

The transverse axis has a length of 5 units.

What is transverse axis and find its length?

A transverse axis is a line that divides a conic section (such as an ellipse or hyperbola) into two symmetric parts. In the case of an ellipse, the transverse axis is the major axis, and it runs perpendicular to the minor axis.

To find the length of the transverse axis, we can use the equation (x − 1)²/a² + (y + 3)²/b² = 1, where a and b are the lengths of the major and minor axes, respectively.

The given equation is :

(x−h)²/a² + (y−k)²/b² = 1

Where h and k are the coordinates of the center of the ellipse.

Now we can substitute the given values in the equation

(x−1)²/25 + (y+3)²/9 = 1

To find the length of the transverse axis, we can take square root of the major axis value, a² = 25

√25 = 5

So the length of the transverse axis is 5 units.

The point-slope form is expressed as;

y - y₁ = m( x - x₁ )

Given that the the graph passes through the points (4, 24) and (6, 30).

Slope m = ( 6 )/( 2 )

Slope m = 3

Next, plug the slope m = 3 and point 1 ( 4,24) into the point-slope form and simplify.

2. The diameter of the cylinder base is given as 19.8 cm and the base area of the cylinder is given as 307.8 cm^2.

3. The volume of the cylinder is given as 9.234 cm^3.

4. If the cylinder and the prism share the same height, the volume of the prism can be calculated by using the base area of the prism.

5. The base area of the prism is given as 196 cm^2.

6. The volume of the prism can be calculated by multiplying the base area with the height of the prism.

7. The volume of the prism is 196cm^2 * h = 6.186 cm^3

The value of the expression when e = 12 and f = 1/2 is 1

How to evaluate the expression

From the question, we have the following parameters that can be used in our computation:

e/4 + 2f - 3

Also, from the question, we have the following values:

e = 12 and f = 1/2

substitute the known values in the above equation, so, we have the following representation

e/4 + 2f - 3 = 12/4 + 2 * 1/2 - 3

Evaluate the expression

e/4 + 2f - 3 = 1

Hence, the solution is 1

find the volume of the solid generated by revolving the region bounded by the parabola y=-(x^2)/9 and the lines y=-1 about the following lines a. the line y=-1 b. the line y=-2 c. the line y=1

Answers

The volume of the solid generated by revolving about the line y=-1 is 324π cubic units and the volume of the solid generated by revolving about the line y=-2 is 216π cubic units.

To find the volume of the solid generated by revolving the region bounded by the parabola y=-(x^2)/9 and the lines y=-1 about a line, we can use the method of cylindrical shells.

a) The line y=-1 is the axis of revolution, so the volume of the solid generated by revolving the region about this line is:

V = ∫[(-1-(x^2)/9)^2 - (-1)^2] * 2πx dx

where the integral is taken over the interval for which the parabola y=-(x^2)/9 is above the line y=-1. So the limits of the integral are from -3 to 3, the volume is:

V = ∫[(-1-(x^2)/9)^2 - (-1)^2] * 2πx dx from -3 to 3 = 324*π cubic units

b) The line y=-2 is the axis of revolution, so the volume of the solid generated by revolving the region about this line is:

V = ∫[(-2-(x^2)/9)^2 - (-2)^2] * 2πx dx

where the integral is taken over the interval for which the parabola y=-(x^2)/9 is above the line y=-2. So the limits of the integral are from -3 to -sqrt(92) = -3 to -3sqrt(2) and 3*sqrt(2) to 3 , the volume is:

V = ∫[(-2-(x^2)/9)^2 - (-2)^2] * 2πx dx from -3 to -3sqrt(2) + ∫[(-2-(x^2)/9)^2 - (-2)^2] * 2πx dx from 3sqrt(2) to 3 = 216*π cubic units

c) The line y=1 is not on the same side of the parabola y=-(x^2)/9 as the region bounded by the parabola and the lines y=-1 so there is no solid generated by revolving about this line.
