TASNOTSCALB58A, B, C And D Are Points On The Circumference Of The Circle, Centre O.DOB Is A Straight

Answers

Answer 1

Answer:

Angle CDB = 32

Step-by-step explanation:

Here, we want to find the measure of CDB

Mathematically;

angle DCB = 90

This is because angle at the center is twice the angle at the circumference

Also;

angle CAD = angle CBD = 58

This is because they are angles in the same segment

Furthermore;

CDB + 90 + 58 = 180

This is because sum of angles in a triangle is 180

CDB = 180-90-58

CDB = 32

She has to buy 48 inches of ribbon

Step-by-step explanation:

We know that the pillow is a square with an area of 144. This means that all the side lengths must be the same. If we take the square root of 144 we get 12 which is the length of one side of the square. Because there are four sides to a square, we multiply this by 4. So 12 x 4 = 48 inches of ribbon.

Which function is the inverse of f(x)=9x-3

Answers

Answer:

The screenshot of my test is below

Step-by-step explanation:

The inverse function is [tex]f^{-1} (x)[/tex]=(x+3)/9.

The given function is f(x)=9x-3.

How to find the inverse of a function?

Steps for finding the inverse of a function f(x).

Replace f(x) with y in the equation describing the function.Interchange x and y. In other words, replace every x with a y and vice versa.Solve for y.Replace y with [tex]f^{-1} (x)[/tex].

Now, y=9x-3

Interchange x and y. That is x=9y-3.

Solve for y.

That is, 9y=x+3

⇒y=(x+3)/9

⇒[tex]f^{-1} (x)[/tex]=(x+3)/9

Therefore, the inverse function is [tex]f^{-1} (x)[/tex]=(x+3)/9.
