Charge of Ralph:
Charge = $24 + $33 per hour
Let the time worked be = x.
For x hours, the cost = 33*x = 33x
Charge = 24 + 33x
24 + 33x = 189
33x = 189 - 24
33x = 165
x = 165/33
x = 5
The job took 5 hours.
I hope this helped
The radical parts are gonna be easiest. You plug the radicals into your calculator and get a decimal. Next, you determine which decimal is greater. For turning fractions into decimals, change the fractions into improper fractions and divide the numerator by the denominator (the top number and the bottom number). You'll get a fraction then compare.
For the graphing area, you do the same thing, turn everything into decimals and place them on the graph.
Good luck!

<span>The answer picture 4.
So the first step is to figure out the sines and cosines of theta (along with their signs in perspective).
The next step is to find the trigonometric functions based on the results of first step. Sine and cosine are defined according to the following convention, with the key lengths shown in green: The hypotenuse has unit length, the side adjacent to has length , and the side opposite has length.</span>
