if the point (9,26) lies on the graph y=f(x) then y=
{inverse function} must contain (26,9)
The inverse of function:
A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. The inverse function is denoted by
or
if the function is represented by "f" or "F"
Given (x,y)=(9,26)
i.e.f(x)=y
⇒f(9)=26
inverse means swap x and y
i.e. y= ![f^{-1}(x)](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29)
⇒
= y
⇒
=9
Therefore, y=
must contain (26,9).

Answer:
18
Step-by-step explanation:
95 divided by 5 equals 19
19-1=18
The angle of B is ![\angle B=19^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20B%3D19%5E%7B%5Ccirc%7D)
Explanation:
It is given that
and ![a=8, b=3](https://tex.z-dn.net/?f=a%3D8%2C%20b%3D3)
To determine the
, let us use the law of sine formula.
Thus, we have,
![\frac{Sin A}{a} =\frac{Sin B}{b}](https://tex.z-dn.net/?f=%5Cfrac%7BSin%20A%7D%7Ba%7D%20%3D%5Cfrac%7BSin%20B%7D%7Bb%7D)
Substituting the values in the formula, we have,
![\frac{Sin 120}{8} =\frac{Sin B}{3}](https://tex.z-dn.net/?f=%5Cfrac%7BSin%20120%7D%7B8%7D%20%3D%5Cfrac%7BSin%20B%7D%7B3%7D)
Multiplying both sides by 3,we get,
![\frac{3(0.866)}{8} ={Sin B}](https://tex.z-dn.net/?f=%5Cfrac%7B3%280.866%29%7D%7B8%7D%20%3D%7BSin%20B%7D)
Simplifying and dividing, we get,
![0.32475=Sin B](https://tex.z-dn.net/?f=0.32475%3DSin%20B)
Multiplying both sides by
, we get,
![\sin ^{-1}(0.32475)=B](https://tex.z-dn.net/?f=%5Csin%20%5E%7B-1%7D%280.32475%29%3DB)
Thus, ![B=18.95^{\circ}=19^{\circ}](https://tex.z-dn.net/?f=B%3D18.95%5E%7B%5Ccirc%7D%3D19%5E%7B%5Ccirc%7D)
Hence, The angle of B is ![\angle B=19^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20B%3D19%5E%7B%5Ccirc%7D)
