Answer:
Step-by-step explanation:
Well, that would be imposible to solve. You are missing the radius. But if the radius was 5, then it would be simple.
Ф=240.0 degreese = 4.19 radians.
x=-2.50
y=-4.33
If the radius is different, then check out this website that me and my team has put togather. http://www.intmath.com/complex-numbers/convert-polar-rectangular-interactive.php
Answer:
40
Step-by-step explanation:
f(4) = 3(4²) - 2(4)
= 3(16) - 8
= 48 - 8
= 40
when x=4, f(x) = 40
It is 6 units because you find the absolute value of the two different coordinates, in this case it is 4 and -2. Since they belong in different quadrants (one x or y value is positive and the other is negative) you add them. If they are both in the same quadrant, you subtract them.
