Itâs a cost-benefit analysis: If it costs you 3 hours weekly to do the wash, but costs you $30 to send it out â that is $10 per hour. But if you bill more than that at your business â or stand to get a raise if you use those three hours to learn new skills, earn a degree, etc., it is worth the investment.
Coordinate Rules for Rotations. In general, we can state the following coordinate rules for (counterclockwise) rotations about the origin: For a rotation of 90o: (x, y) --> (ây, x) For a rotation of 180o: (x, y) --> (âx, ây) For a rotation of 270o: (x, y) --> (y, âx)
1. Write down the formula for finding the circumference of a circle using the diameter. The formula is simply this: C = Ïd. In this equation, C represents the circumference of the circle, and d represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.Plugging Ï into your calculator will give you its numerical value, which is a closer approximation of 3.14.Ad.n this equation, C represents the circumference of the circle, and d represents its diameter.
