Pi/3 is equivalent to 60 degrees, as 2pi is equal to 360 degrees. cos(60) in a triangle yields 1/2, and sin(60) yields (3^(1/2))/2. Thus, -pi/3, or -60 degrees would be a fourth quadrant point on the unit circle and these values would be negative as well, at cos(-pi/3)=-1/2 and sin(-pi/3)=-(3^(1/2))/2

Step-by-step explanation:
This is a special die. Its six sides bear the numbers {9, 10, 11, 12, 13, 14}.
There are three possibilities for getting a multiple of two: {10, 12, 14}, and
there is only one possibilities for getting a multiple of ten: {10, 12, 14}
The probability here of getting a multiple of two is 3/6, and that of getting a multiple of ten is 1/6. But one of the outcomes is found in both result sets: 10. Getting a multiple of 10 is already included in the event that the outcome is a multiple of two. My answer here would be 3/6, or 1/2.
Answer:
Step-by-step explanation:
Since RQT=155
4x-20+3x+14=155
7x-6=155
7x=161
x=23
Answer:
<em>The expression is </em><em>P - 5</em>
Step-by-step explanation:
Rihanna already made a deposit of $5 to buy the necklace (given)
Full price of necklace = P
Let m = how much Rihanna has left to pay
Full price of necklace = amount paid + amount left to pay
= 5 + m
So we equate the two full necklace prices
5 + m = P
m = P - 5
Therefore, the amount Rihanna owes before tax = P - 5
