Yes, that seems like the right answer. So no they dont have enough paint to finish the job on Wednesday.
Answer:
B= 4.6cm
Step-by-step explanation:
A=
To use De Moivre's theorem, we first write -2i is cis form: 0 - 2i has r = 2 and theta = 270.
Then we take the cube root, which means the new result will have r^(1/3), and the angle (theta/3). This means r = cbrt(2) and theta = 90.
This means that the answer is (cube root of 2)(cos90 + i*sin90), choice C.
I suspect the choices "3sqrt2" is actually a cube root of 2, not 3 multiplied by the square root of 2.
Remember that parallel lines have the same slope.
y=3/7x+11 (in slope intercept form already)
-3x+7y=13 (standard form)
Add 3x to both sides, giving you 7y=3x+13, divide by 7 on both sides, giving
y=3/7x+13/7
Since both equations' slopes' are the same, their graphs will be parallel.
