How can you use rates to determine wheather a situation is a proportional relationship

Mathematics
1 answer:
svp [43]3 years ago
7 0

<em>If the rate is a constant, the relationship is proportional.</em> (The rate is the constant of porportionality.)

_____

For two or more points on the function curve, divide the dependent variable value by the independent one. If you get the same result in every case, the relationship is porportional.

___

<em>Note</em>

For some non-proportional relationships, it is possible to find points on the graph that will pass the above test. If you suspect the relationship is actually not one of proportionality, try more points. Check also to make sure that (0, 0) is on the curve.

For which angle theta is cos theta =-1?<br>a) 270<br>b) 360<br>c) 450<br>d) 540​
yanalaym [24]

Answer:

540°.

Step-by-step explanation:

On a unit circle, cos θ = -1 at 180°.

However, cos θ has a period of 2π, or 360°. This means that cos θ will equal to -1 again after 2π.

To solve for the angle:

180° + 360° = 540°. This is the next angle at which cos θ = -1.
