If g(x) = {(4, -5), (-3, 2), (-6, 1), (1,0)}, which set of ordered pairs represents
Ket [755]

Answer:

The inverse of g(x) is {(-5, 4), (2, -3), (1, -6), (0, 1)} ⇒ (A)

Step-by-step explanation:

To find the inverse of a function switch x and y

<u>Example:</u>

If f(x) = {(1, 2), (-4, 5), (0, 0)}

To find its inverse switch x and y in each ordered pair

The inverse of f(x) = {(2, 1), (5, -4), (0, 0)}

<em>Let us do the same with our question</em>

∵ g(x) = {(4, -5), (-3, 2), (-6, 1), (1, 0)}

→ Switch x and y coordinates in all ordered pair

∴ The inverse of g(x) = {(-5, 4), (2, -3), (1, -6), (0, 1)}

<em>Look at the answer to find the correct choice</em>

It is (A)

Find the side AB using the law of sines with the one of the sides 11 and the angles 82 and 44 degrees
Rasek [7]

Answer:

7.7

Step-by-step explanation: We are trying to find side c  or side AB

Using the law of sines formula,

a/sin a= b/sin b c/sin c we can solve for missing side.

We are  given side BC or side a which is 11

We also are given angle A is 82 degrees

Angle C is  44 degrees also.

So let set up a proportion.

11/sin 82= x/sin 44

11/sin 82× sin 44=x

x= 7.7
