Answer:
Graph is below
Step-by-step explanation:
I graphed the point on the graph below.
Answer is D. 3000. This is because 1.2*10^3=1200 and 4*10^-1=.04 so using the equation .4x=1200 when x=300 makes the equation true.
Sin(225)
225 degrees is in the 3rd quadrant. And in the third quadrant only tangent is positive, sin is negative.
For third quadrant, basic angle = 225 - 180 = 45
sin225 = - sin45
sin225 = - sin45 = -0.7071
sin 225° ≈ -0.7071
What triangle?? can you be more specific?
