Answer:
In the 3rd and 4th quadrants of the coordinate system
ie π < θ < 2π. At π and 2π the sine values are zero
Step-by-step explanation:
>
Hence, x = 0°, 180° and 360° <em><u>Ans</u></em>
Answer:
T' 
Step-by-step explanation:
See the diagram attached.
This is a unit circle having a radius (r) = 1 unit.
So, the length of the circumference of the circle will be 2πr = 2π units.
Now, the point on the circle at a distance of x along the arc from P is T
.
Therefore, the point on the circle at a distance of 2π - x along the arc from P will be T' , where, T' is the image of point T, when reflected over the x-axis. (Answer)

Answer:
a is 800
b is 13
c is 61.5
Step-by-step explanation:
for a you add all of the given data together
b you count how many data points there are
c you get the answer from the a and divided by 13
Answer choice A is incorrect as it is missing the variable 'x' in it.
Let's test answer choice B.
y = mx + b
m is the slope
b is the y-intercept
m = 2/3
b = -5
y = (2/3)x - 5
B is one of the answers.
Let's test answer choice C.
6y = 4x -30
y = (4/6)x - 30/6
y = (2/3)x - 5
Answer choice C is also correct.
Let's test answer choice D now.
y = (2/3)x - 5
Plug in (3,-3)
-3 = (2/3)(3) - 5
-3 = 2 - 5
-3 = -3
This is correct, so therefore D is also one of the answers.
Your answer is B, C and D.
