Answer with Step-by-step explanation:
For any complex number x+iy the polar form is represented as

where

Part a) x+iy = -1+i
Thus 
Thus using De-Morvier's theorem

Part 2) x+iy = 1+3i
Thus 
Thus using De-Morvier's theorem

Answer:
Step-by-step explanation:
You only need one, but to use two let's go from cm to mm an then mm to inches. there are 100 mm^2 in a cm^2 so that's 100 mm^2/ 1 cm^2 and then there's 645.16 mm^2 in one square inch so that one will be 1 in^2/ 645.16 mm^2 so writing it out we get:
62 cm^2 * 100 mm^2/ 1 cm^2 * 1 in^2/ 645.16 mm^2
units all cancel out to get in^2 an then you just multiply 62*100/645.16 = 9.61 so that leaves us with 9.61 in^2.
Let me know if there's something you don't understand.
Each tricycle has 3 wheels and one seat, so the ratio of seats to wheels is 1:3
The answer is C because there is an open circle(not including the number it's on) on the 60 mark and the arrow goes to the left, or to the lower numbers.
