find the inverse of 8x^5+7

Answers

Answer 1

The inverse of a function is another function that "undoes" the original function. In other words, the composition of a function and its inverse results in the identity function.

To find the inverse of a function, you can follow these steps:

Replace the function with "y"

Switch the x and y variables

Solve for y (or in this case x)

So in this case, we can find the inverse of 8x^5+7 by replacing y with 8x^5+7, switching the x and y variables, and solving for x:

y = 8x^5+7

x = 8y^5+7

This is not an invertible function because it's not a one-to-one function, it's not a function of x.

Answer 2

Answer:

Hey there! The inverse of 8x^5+7 doesn't exist because it's not a function. Think about it like this, a function is like a machine that takes an input and gives you a unique output. But in this case, the machine isn't working correctly and it doesn't give you a unique output for a given input. So, in simple terms, it doesn't have an inverse.

________________________________________________________

How do you determine if an equation has an inverse?

To determine if an equation has an inverse, we need to check if it is a one-to-one function. A one-to-one function is a function in which every unique input corresponds to a unique output. If an equation is one-to-one function, then it has an inverse. If it's not one-to-one function, then it doesn't have an inverse.

How do you find the inverse of a linear equation?

To find the inverse of a linear equation, we can follow these steps:

1. Switch the x and y variables

2. Solve for y (or x)

3. Replace y (or x) with f^-1 (x) (or f^-1 (y))

For example, if we have the equation y = 2x+1, we can follow these steps:

1. x = 2y+1

2. x-1 = 2y

3. f^-1(x) = (x-1)/2

So, the inverse of the equation y = 2x+1 is f^-1(x) = (x-1)/2

find the volume v of the described solid s. the base of s is the triangular region with vertices (0, 0), (5, 0), and (0, 5). cross-sections perpendicular to the x-axis are squares.

Answers

Using the disk method, it can be concluded that the volume of the solid is 125π /3 cubic units.

Disk Method is a method used to determine the volume of a solid formed by revolving the region about the x-axis and the interval [a, b]. The volume of the solid is the integral of the area of the base times dx.

V = π ∫ Ax dx

From the question, we know that the base of the figure is a triangular region and the coordinates are (0,0), (5,0), and (0,5).

The square is perpendicular to the x-axis. Thus, we can find the side of the square, that is the straight line passing through (5,0) and (0,5) which meet the y = mx + b equation.

First, we determine the slope of the line (m).

m = (y₂ - y₁) / (x₂ - x₁)

   = ( 5 - 0 ) / ( 0 - 5 )    

   = 5 / -5

   = -1

To find b, we input the value of m into the equation for point (5,0):

y = mx + b

0 = -1*5 + b

0 = -5 + b

b = 5

So we got the side of the square:

y = mx + b

y = -x + 5

y = 5 - x

Thus the area of the square is:

A = side²

  = (5 - x)²

  = 25 + x² - 10x

The volume of the solid can be calculated as follows:

   V = π ∫ Ax dx

      = π ∫₀² (25 + x² - 10x) dx

      = π (25x + 1/3x³ - 5x² |₀⁵)

      = π (25*5 + 1/3*5³ - 5*5² - 0)

      = π (125 + 125/3 - 125 - 0)

      = 125π /3 cubic units

Thus, the volume of the solid is 125π /3 cubic units

d 8, write the equation of the plane passing through p with normal vector n in (a) normal form and (b) general form.

Answers

The equation of the plane  passing through point P with normal vector n A(x-2) + B(y-3) + C(z-4) = 0

(a) Normal Form:

The equation of the plane passing through point P with normal vector n can be written in normal form as:

n • (r - p) = 0

where r is a position vector in three-dimensional space and n is the normal vector of the plane.

Given n = (1,2,3) and p = (2,3,4).

Therefore, n • (r - p) = (1,2,3) • (r - (2,3,4)) = r1 + 2r2 + 3r3 -2 - 3 - 4 = 0

=> r1 + 2r2 + 3r3 - 8 = 0

=> Plane equation in normal form: 1x + 2y + 3z - 8 = 0

(b) General Form:

The equation of the plane passing through point P with normal vector n can also be written in general form as:

A(x-x0) + B(y-y0) + C(z-z0) = 0

where A, B and C are the components of the normal vector n and (x0,y0,z0) are the coordinates of the point p.

Given n = (1,2,3) and p = (2,3,4).

Therefore, A(x-2) + B(y-3) + C(z-4) = 0

=> 1(x-2) + 2(y-3) + 3(z-4) = 0

=> Plane equation in general form: x - 2y + 3z - 8 = 0

Option C. They will walk 9 laps and run 15 laps for a total of 24 miles.

How to calculate for the table

The table is given as Walk (laps) 3 B 15

Run (laps) 5 10 D

Total (laps) A C 40

The total for walk and run is 3 + 5 = 8

Walk is 3

Run is 5

We are to find the laps of both categories with respect to the total distance of 24 miles

for walk = 3/8 * 24

= 9

For run we would have 5 / 8 * 24 = 15

Hence They will walk 9 laps and run 15 laps for a total of 24 miles.

A rectangle has a length of 8.2cm and a height of 42mm. The area of the rectangle is mm2

Answers

Answer: To find the area of a rectangle, you can use the formula:

Area = Length x Height

In this case, the length is given in cm and the height is given in mm. Therefore, you need to convert the length to mm before you can calculate the area.

1cm = 10mm.

So, 8.2 cm = 8.2 x 10 = 82mm

Now you can find the area of the rectangle:

Area = Length x Height = 82mm x 42mm = 3,444 mm^2

So, the area of the rectangle is 3,444 mm^2

By constructing 95% confidence intervals for each simulation, we can be 95% confident that the true proportion of wins lies within the range of each interval.

What is Confidence Intervals?

A confidence interval is a set of values that, given a specific level of certainty, are likely to include a population parameter like a mean or proportion.

The interval is derived using data drawn from a sample of the population and is frequently presented as a range of values with a 95% confidence level.

The probability that the range of values contains the genuine population parameter is quantified by the confidence level.

In the case of a 95% confidence interval, for instance, it means that 95% of the intervals would contain the real population parameter if we sampled the same population more than once and calculated a confidence interval each time.

Find the solutions to the equation:
2x² - 10x + 15 = x

Answers

5/2 and 3 are the solutions to the equation 2x² - 10x + 15 = x.

What is equation?

An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =. In its most basic form, an equation is a mathematical statement that shows that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical equation that depicts the relationship between two expressions on opposite sides of the sign. It mostly consists of one variable and one equal to symbol. 2x - 4 = 2 is an example.

Here,

2x² - 10x + 15 = x

2x² - 11x + 15 = 0

2x² -6x -5x + 15 = 0

2x(x-3)-5(x-3)=0

x=5/2, 3

The solutions to the equation 2x² - 10x + 15 = x is 5/2 and 3.

A solution to the given system of equations include the following:

x = -2.

y = -1.

How to solve this system of equations?

In order to solve the given system of equations, we would apply the substitution method. From the information provided in the image attached above, we have the following system of equations:

y = 2x + 3      .......equation 1.

y = 3x + 5      .......equation 2.

By using the substitution method to substitute equation 1 into equation 2, we have the following:

2x + 3 = 3x + 5

By re-arranging and collecting like terms, we have the following:

3x - 2x = 3 - 5

x = -2.

For the value of y, we have the following:

y = 2x + 3

y = 2(-2) + 3

y = -4 + 3

y = -1.
