The option A is showing the domain ans the range of the function F(x) as inverse of F(x).

What is inverse function?

In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by [tex]{\displaystyle f^{-1}.}[/tex]

Here in the graph we can see that the option A has the clear range of the function.

Find the value of x in the parallelogram below.

Answers

Answer:

x = 25

y = 6

Step-by-step explanation:

In a parallelogram, opposite angles are equal.

2x and 50 are opposite angles,

2x = 50

Divide 2 on both sides,

x = 50 / 2

x = 25

In a parallelogram opposite sides are equal.

y + 5 and 11 are opposite sides,

y + 5 = 11

y = 11 - 5

y = 6

Answer:

x=25

y=6

Step-by-step explanation:

from the diagram,

2x= 50(opposite angles of a parallelogram)

2x= 50

dividing bothsides by 2

2x/2=50/2

x= 25

then,

y+5=11(opposite sides of a parallelogram)

y= 11-5

y= 6

A square has an area of 81 square inches. What is its perimeter?

Answers

Area of square = [tex]s^2[/tex] where, [tex]s[/tex] is the side length of the square.

[tex]81=s^2[/tex]

[tex]9=s[/tex]

s must be positive since it is a side length, so the negative root of 81 is rejected.

Perimeter= [tex]4s[/tex]

Perimeter= [tex]4(9)=36inches[/tex]

Step-by-step explanation:

In order to find the perimeter we need to find the length first ...

...Here, the area is already given ...

Area = 81 inches square

length = ?

Now....

( The formula of area is l × l )

[tex]area = {l}^{2} [/tex]

[tex]81 = {l}^{2} [/tex]

Now we should find square root of 81...

[tex]l = \sqrt{81} [/tex]

[tex]l \: = 9[/tex]

Now we find length so it's easy for us to find perimeter...

The formula of perimeter of square is 4l ..

= 4l

= 4 × 9

= 36 inches

hence the answer is 36 inches....
