Answer:
39 Mr Jones
35 Mrs. Jones
8 Son
Step-by-step explanation:
x ----> Mr. Jones
x - 4 ----> His wife
x - 31 ---> His son
x + (x - 4) + (x - 31) = 82
3x - 35 = 82
3x = 82 + 35
3x = 117
x = 117/3
x = 39 Mr Jones
x - 4
39 - 4
35 Mrs. Jones
x - 31
39 - 31
8 Son
To use a unit circle, you must know where the coordinates are.
For this problem it is asking you where the sin(11pi/6) is.
You look at the unit circle for 11pi/6.
From here you look at the coordinates.
The x value is the cosine and the y value is the sine.
This means that the sin of 11pi/6 is -1/2.
To find the csc or the cosecant you just find 1/sin.
To find the the sec or secant you find 1/cos.
To find the tangent or tan you find the sin/cos.
And to find the cot or cotangent you find 1/tan.

A.) The average rate of change is $0.50, meaning that for each minute of talk time, the monthly bill increases by $0.50.
B.) The average rate of change is $0.50, meaning that for every ten minutes of talk time, the bill increases by $0.50.
C.) The average rate of change is $0.05, meaning that for each minute of talk time, the monthly bill increases by $0.05.
D.) The average rate of change is $0.05, meaning that for every ten minutes of talk time, the bill increases by $0.05.
For this case, the first thing we must do is find the average rate of change for the mentioned interval.
By definition we have to:
Substituting values we have:
Rewriting we have:
Answer:
C.) The average rate of change is $0.05, meaning that for each minute of talk time, the monthly bill increases by $0.05.
