52
Step-by-step explanation:
I don't really know what the other numbers are for but I'll just answer the first line.
Basically, you have to find what 10% of 130 is and multiply that number by 4.
130/10 = 13 (10% of 130)
4(13) = 52 (40% of 130)
You can verify this by typing in your calculator (130 x 0.40) and you should get 52.
You can also take 100% of 130 and substract by 60% of 130 to find 40%.
Answer:
3π/2
Step-by-step explanation:
It may help you to realize that the (x, y) coordinates of the point on the unit circle are ...
(x, y) = (cos(θ), sin(θ))
Since you want sin(θ) = -1, look for the point on the unit circle that has a y-value of -1. It is the point (0, -1) at the bottom of the circle, where the angle is shown as ...
θ = 3π/2
