Replace every x with a y and replace every y with an x .

Solve the equation from Step 2 for y . ...

Replace y with f−1(x) f − 1 ( x ) . ...

Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.

Answer 2

The steps for finding the inverse of a function are given below.

What is an inverse of a function?

A function accepts values, performs particular operations on these values and generates an output. The inverse function agrees with the resultant, operates and reaches back to the original function.

Steps for finding the inverse of a function f.

Replace f(x) by y in the equation describing the function.

Interchange x and y. In other words, replace every x by a y and vice versa.

Solve for y.

Click on the graph until the graph of a line with undefined slope appears.

Answers

Answer:

The graph with the vertical line.

Step-by-step explanation:

All vertical lines have an undefined slope.  Horizontal lines have zero slope, and diagonal lines have a slope.

When calculating a slope for a vertical line, you would have to divide by zero. The quotient of any number and 0 are undefined, as you cannot divide by zero.  This is what makes vertical lines have an undefined slope.

Answers

Answer: girls=20, sister=10

Step-by-step explanation:

Let x = the girl's sister's age (present)

Let 2x= the girl's age (present)

-------------------------------------------------------------

According to the question

(x+5)(2x+5)=375

Expand parentheses by FOIL (First Outer Inner Last)

2x²+5x+10x+25=375

Combine like term (5x and 10x)

2x²+15x+25=375

Subtract 375 on both sides

2x²+15x+25-375=375-375

2x²+15x-350=0

Find the factors (cross factor)

(x-10)(x+17.5)=0

x=10 or x=-17.5 (rej) ⇔ the age can't be negative

the girl's age is 20, and her sister's age is 10.

Step-by-step explanation:

Given

Solve for B

[tex]g = mB - 2qB[/tex]

Factorize the expression

[tex]g = B(m - 2q)[/tex]

Divide both sides by m - 2g

[tex]\frac{g}{m-2g} = \frac{B(m - 2q)}{m-2g}[/tex]

soolve the abslut value of |2x-1|=3

Answers

Answer: x = 2 or x = -1

Step-by-step explanation: When you are solving an absolute value equation, you can split the problem up into two separate equations.

The first equation will look just like the original problem,

except for the absolute value signs (2x - 1 = 3).

The second equation will look just like the first,

but the right side will be changed to a negative (2x - 1 = -3).

Now solve each equation from here to get x = 2 or x = -1

A rectangular prism has a volume of 170 cubic centimeters. The length of the prism is 5 centimeters, and the height of the prism is 17 centimeters. What is the width of the prism. Enter the answer in the box .

Answers

Answer:

The width of the prism is 2 cm

Step-by-step explanation:

The given parameters are;

The volume of the prism = 170 cm³

The length of the prism = 5 cm

The height of the prism = 17 cm

The volume of the prism is given by the  relationship v = Length, l × Height, h × Width, w

Therefore;

The volume of the prism = 5 cm × 17 cm × w = 170 cm³

Which gives;

w = 170 cm³/(5 cm × 17 cm) = 170 cm³/(85 cm) = 2 cm

∴ The width of the prism = 2 cm.

The width of the prism is 2cm given length of the prism is 5 centimeters, and the height of the prism is 17 centimeter.

The formula for calculating the volume of a rectangular prism is expressed as:

V = LWH where:

L is the lengthW is the widthH is the height

Given the following:

V = 170cm³

L = 5cm

H = 17cm

Required

Width

Substitute the given values into the formula:

170 = 5 * 17 * W

170 = 85W

W = 170/85

W = 2cm

Hence the width of the prism is 2cm

y = -0.2*x^2 is a vertical dilation of scale factor 0.2 followed by a reflection over the x-axis of y = x^2

How to relate these two graphs?

We have two functions:

f(x) = x^2

g(x) = -0.2*x^2

The transformations used are:

Reflection over the x-axis.

For a function f(x), a reflection over the x-axis is written as:

g(x) = -f(x).

Vertical dilation.

For a function f(x), a vertical dilation of scale factor k is written as:

g(x) = k*f(x).

So here we can see that we have a vertical dilation of scale factor 0.2, followed by a reflection over the x-axis.

g(x) = -0.2*f(x).

So, g(x) opens in the opposite direction than f(x), and grows slower (because of the dilation).

The path of water from a hose on a fire tugboat can be approximated by the equation y=-0.0055x^2 +1.15x + 5, where y is the height above the ocean and x is the distance from the tugboat. When the water is 6 ft above the ocean how far is it from the tugboat

Answers

Answer:

The water is 208.22ft from the tug boat

Step-by-step explanation:

The governing equation is [tex]y=-0.0055x^2 +1.15x + 5[/tex]

y is the height above the ocean

x is the distance from the tugboat

if y= 6ft, the equation will now become

[tex]6=-0.0055x^2 +1.15x + 5[/tex]

we can arrange this properly to form a quadratic equation by grouping like terms.

[tex]-0.0055x^2 +1.15x -1=0[/tex]

solving quadratically we have two values of x as  208.22ft and 0.873 ft.

The general equation of a straight line graph is y = mx + c, where m is the gradient of the line and c is the y-intercept.

Gradient = (2 - (-18)) / (3 - (-2)) = 20/5 = 4.

So y = 4x + c.

When x = 3, y = 2. (Given in the question)

This means that 2 = 4(3) + c, hence c = -10.

A. –19

B. 125

C. 19

D. 55

Answers

The answer I think is -19 because of the intercepting lines

The value of x is 19. Therefore, option C is the correct answer.

From the given figure, the two angles are (7x-8)° and (6x+11)°.

What is the vertical angle theorem?

Vertical angles are a pair of non-adjacent angles formed by the intersection of two straight lines. In simple words, vertical angles are located across from one another in the corners of the "X" formed by two straight lines. They are also called vertically opposite angles as they are situated opposite to each other.

Now, (7x-8)° = (6x+11)° (Vertically opposite angles are equal)

⇒ 7x-6x = 11+8

⇒ x = 19°

The value of x is 19. Therefore, option C is the correct answer.

Tina has 1/2 of a pan of cornbread left from a dinner party. She eats 1/2 of the leftover part the next night. How much of the whole pan does tina eat? Write and solve this equation

Answers

Answer:

Tina ate 3/4 of the whole pan of cornbread.

Step-by-step explanation:

Let the amount of cornbread in the initial pan be x.

After the dinner party, Tina has 1/2 of x left; That is 1/2x

If she eats 1/2 of the leftover, that will be 1/2 of 1/2x that is eaten. This will be 1/4x that is eaten.

To find the potion of the whole pan that Tina ate, we will add the potion she ate during the party to the portion of the leftover she ate the next night.

That will be 1/2x + 1/4x =3/4x

Therefore, Tina ate 3/4 of the whole pan of cornbread.
