Imagine the unit circle. The cot(theta) is a line from (0,1) to (-4,1). Imagine it is part of a triangle with the origin (draw it!).
Then the hypotenuse length is √(1+4²) = √17.
The sine rule says that sin(90)/√17 must equal sin(theta)/4, and sin(90)=1, so
<u><em>Answer:</em></u>
<u><em>Well first we must see if they are proportional.

<u><em>46.2/6 = 10.7.8/14

<u><em>7.7 = 7.7

<u><em>They are proportional. The rate of proportion is 7.7 ounces per cellphone. Hope this helps!

<u><em>Step-by-step explanation:</em></u>
well, let's assume you haven't been dead for 3 years then, 30,400 a year, expressed as a unit rate per hour?
assuming a year has 365 days.
a day has 24 hours, therefore a year will have 365*24 hours.
so 30400 per year, will be 30400/(365*24) per hour, namely about 3.47031963, which we can round up to about 3 deaths per hour.
the frequency of the sinusoidal graph is 2 in 2 π interval
Step-by-step explanation:
The frequency of the graphs refers to the number of the cycles, the graph completes in a given fixed interval.
We already know the formula that
P= (1/ F)
Thus, F= (1/ P)
Where F= frequency and P= Period
Period is the horizontal length (x- axis component) of one complete cycle.
Thus, Observing the above graph
We find that the graph completes 1 cycle in π interval and 2 cycles in 2π interval
Thus, the frequency of the sinusoidal graph is 2 in 2 π interval
