Answers

Answer 1

Answer: sin(15) = 0.258819045103
cos(15) = 0.965925826289
tan(15) = 0.267949192431
all you do is get a graphing calculator input sin(15), then cos(15), and tan(15), make sure the calculator is in degrees not radians hit enter or what ever the answer button is and it should tell you your answer

Answer: D

Step-by-step explanation:

The orange color is represented by the bottom line, which is y > x - 2

The purple color is represented by the top line, which is y < x + 1

How do we know the equations of those lines?

The equations can be written in the form y = mx + b where;
m = slope
b = y-intercept

The orange line:

crosses the y-axis at -2 --> b = -2
has a rise over run of 1 -> m = 1
--> y = x - 2
the line is dashed and is shaded above so y > x - 2

The purple line:

crosses the y-axis at +1 --> b = 1
has a rise over run of 1 -> m = 1
--> y = x + 1
the line is dashed and is shaded below so y < x + 1
