Answer:
90
Step-by-step explanation:
- change mixed number to improper fraction 22 1/2 = 22*2+1/2 = <u>45/2</u>

Answer:
B
Step-by-step explanation:
For cartesian to polar transformation,
x = rcosA , y = rsinA.
Put in the values in the given equation. And (cosA)^2 - (sinA)^2 = cos(2A)
For every centimeter that is drawn, it corresponds to 1 meter in real.
Knowing that every meter has 100 centimeters:
