Answer:

Casey's Function has the greater rate of change

Step-by-step explanation:

The graph shows a ROC of 5/1

Get a common denominator (4)

5/1 * 4/4 = 20/4

20/4 > 13/4

Casey's function has a greater ROC.

Please help ASAP! Algebra 2!<br> The choice options for both are negative or positive
Alinara [238K]

In quadrant III, cosine is <u>negative</u>

In quadrant III, sine is <u>negative</u>

x^2+y^2 = 1 represents the unit circle. This is a circle centered at the origin with radius 1. The point (x,y) is on the unit circle where x = cos(theta) and y = sin(theta)

If theta is between 180 and 270 degrees, then

x = cos(theta) leads to -1 < x < 0, ie x is some negative number between -1 and 0

y = sin(theta) leads to -1 < y < 0, so y has similar properties to x above.

Because we don't know what value theta is exactly, we can only comment on the fact that each result is positive or negative.

The four quadrants are set up where quadrant 1 is in the upper right corner. Then you move counter-clockwise to sweep through the other quadrants 2 through 4.

I need help figuring out when to use law of sine or law of cosine?
irina [24]
When you have angle and its corresponding (opposite) side then you need to use law of  sin. Problems 3,4,5(in 5 you need at first find angle X=180-92-62)


when you have two sides and angle between them, this is law of cos, problem 6,8

problem 7 you can use both, but if you can use both better to use law of sin, it is just easier
