Answer:
We verified that the equation
has both sides equal.
Step-by-step explanation:
We need to solve and verify: 
Solving:

Converting into improper fractions

Converting division sign into multiplication and reversing 3/2 i.e

Now simplifying

So, We verified that the equation
has both sides equal.
Answer:

Step-by-step explanation:
In any right triangle, the cosine of an angle is equal to its adjacent side divided by the hypotenuse, or longest side, of the triangle.
Therefore, we have:

Answer:

And we want to compare the two functions.
The minus signs is a reflection around the x axis and the value of 2/3 is a compression of the original function so then the best answer would be:
The graph of g(x) is the graph of f(x) compressed vertically and reflected over the x axis
Step-by-step explanation:
We have the following two function given:

And we want to compare the two functions.
The minus signs is a reflection around the x axis and the value of 2/3 is a compression of the original function so then the best answer would be:
d) The graph of g(x) is the graph of f(x) compressed vertically and reflected over the x axis
