Let's start with the fact that this is a function.  Each element of Set A is paired with exactly one element of Set B.

This makes Set A the set of inputs and Set B the set of outputs.

There are a lot of other boxes to pick from, so I'm not sure what else you'd need to pick to make your answer correct.

COMPLETE<br> Find the value of the function for O.<br> sin(45°) = ?
geniusboy [140]

Answer:  \sqrt{2}/2 which is Choice B

This is the same as writing \frac{\sqrt{2}}{2}

The second "2" is not under or inside the square root.

==========================================================

Explanation:

Refer to the unit circle below. I've highlighted the angle 45 degrees and its corresponding sine value. It's the y coordinate of the point on the unit circle, for this particular angle.

Therefore, \sin(45^{\circ}) = \frac{\sqrt{2}}{2}

--------------

You could alternatively draw out a 45-45-90 triangle. Let x be the leg length and the hypotenuse is 1 unit long. Solve x^2+x^2 = 1 for x and you should get x = \frac{\sqrt{2}}{2} as the length of each leg.

Then take the ratio of the opposite over hypotenuse to find the same answer mentioned above.

Write 19/25 as a terminating decimal
mariarad [96]
Terminating decimals firstly are decimals that finish... 
To transfer 19/25 to a decimal we have to get it out of 100. 
To do this, multiply 19 by 4, and 25 by 4. 
This gives you 76/100.
From here you can easily see the decimal is 0.76. 

= 0.76
