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

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.
