This happens whenever the terminal point of

lies in either the first or second quadrants.
Meanwhile,

since you already know sine is positive. Cosine is positive when the angle lies in the first or fourth quadrant.
Sine and cosine are both positive only when

is the first quadrant, which means this angle's terminal point lies in the first quadrant (A).
Answer:
x = 6, y = 0, m = -1
y = mx + b
0 = -1(6) + b
0 = -6 + b
6 = b
y = -1x + (6)

See answer, pretty simple.
It is B 80. Because it is 40 x 2 = 80. Hope thishelped
Answer:
2/17
Step-by-step explanation:
Add all the marbles and add the 2 in front because 2 is what you are taking, and 17 is the total of marbles.
It will take 6 years for that to happen.
You can find this by setting Nichole's age as x and Sophie's age as x + 28 since she will always be 28 years older.
Now we are looking for a time that Sophie's age is equal to 2 less than 6 times Nichole's age. So we can set up the below equation.
6(x) - 2 = x + 28
6x - 2 = x + 28
5x - 2 = 28
5x = 30
x = 6
This let's us know that it needs to be when Nichole is 6, which is 6 years in the future.
