Answer:
Step-by-step explanation:
Given:
Angle is in standard position which means the starting ray is at the origin. The terminal side has coordinates (3, -4).
So, the 'x' value is 3 and 'y' value id -4.
Using Pythagoras Theorem, we find the hypotenuse.
Hypotenuse = 
Now, using the sine ratio for the angle, we have
Therefore, the value of 
is 
.
The value is negative as the point (3, -4) lies in the fourth quadrant and sine ratio is negative in the fourth quadrant,
Answer:probably x’s all of them
Step-by-step explanation:
Answer: No. You reversed the domain and range
#2) B) x ≥ 0
#3) B) [0, ∞)
<u>Step-by-step explanation:</u>
#2 is asking about the domain, which is all of the x-values.
The graph appears to be touching the y-axis so it equals 0 and all other x-values are greater than zero. (0, 1), (1, 0), (2, -0.8), (3, -1.5), etc. All of the x-values are moving toward the right, which is positive infinity. --> x ≥ 0
#3 is asking for the range, which is all of the y-values.
The vertex is at (0, 0) and all other y-values are above zero (positive numbers), moving toward positive infinity. --> [0, ∞)
