Answer:
-4
Step-by-step explanation:
[√2(cos(3π/4) + i sin(3π/4))]⁴
(√2)⁴ (cos(3π/4) + i sin(3π/4))⁴
4 (cos(3π/4) + i sin(3π/4))⁴
Using De Moivre's Theorem:
4 (cos(4 × 3π/4) + i sin(4 × 3π/4))
4 (cos(3π) + i sin(3π))
3π on the unit circle is the same as π:
4 (cos(π) + i sin(π))
4 (-1 + i (0))
-4
Answer:
I believe it is 40% since there are 4 marbles within the bag!
Step-by-step explanation:
y=mx+b
m=slope
b= y intercept (when x = 0
y= y value
x=x value
you already have your slope given plug in you x and y values into the equation and reverse the math, like you would do to "solve for X this time B"
you will then get you whole equation

this is the answer I have done.
