The value of x is 4
Hope this helps
For example:
Find: (3-i)+(2+3i) by graphing
Step 1: Graph 3-i and 2+3i on the complex plane. Connect each of these numbers to the origin with a line segment.
All of the above options are true, so the answer is choice D.
The answer is B. To find the Circumference (what you're looking for) you use 2×pi×radius. Which is 2×pi×7. In terms of pi that's just 2×7, which equals 14. So that means your answer is 14pi.
I think it D cause 30(cos(30x)+14=-16
Your dividing by 30
your 180 (which is degrees) is
radians. As the cosine function is periodic with period 2 we get
