How do i solve this? im looking for the answer but also an explanation on how to do this so i can understand it.

SOH CAH TOA is a mnemonic that can help you remember

Sin = Opposite/Hypotenuse

Cos = Adjacent/Hypotenuse

Tan = Opposite/Adjacent

In the given figure, you have the side Adjacent to the angle, and you have the Hypotenuse. Thus the Cosine relation is useful to you.

... cos(45°) = 12/c

Multiply by c/cos(45°) to get

... c = 12/cos(45°)

Use your calculator and/or your knowledge of the values of the trig functions to determine cos(45°) = 1/√2, so ...

... c = 12√2 ≈ 16.97

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
