You can compare properties of two functions each represented in a different way by saying them out loud (verbally), seeing them as they are by numbers (numerically), and even how they are seen (visually).

Answer:
Coordinate -1, 3
Step-by-step explanation:
For part (a), we know that 6/60 pupils wear glasses. We also know that there are 360 degrees in the pie chart. So the angles for people who wear glasses must be (6/60)*360. 6/60 simplifies to 1/10, and a tenth of 360 equals 36. So the angle must be 36 degrees. To find the other angle, simply subtract 36 from 360 degrees to get 324 degrees.
For part (b), it is not possible to tell because all 6 pupils who wear glasses could be girls, they could all be boys, some girls and some boys, etc. We cannot know which one it is, given only that much information.

The lowest balance she had was $-45 and the highest balance is $150
(5+3i)(8-2i). We will FOIL this out like anything else. 5*8 = 40; 5*2i = 10i; 3i*8 = 24i; 3i*-2i = -6i^2. Putting that all together we have 40+10i+24i-6i^2. Simplifying we have 40+34i-6i^2. i^2 = -1, s0 -6*-1=6. Now let's rewrite. 40+34i+6 = 46 + 34i. That's the product.
