Pls help ASAP. 13. The temperature in our school is modeled with this equation: T = 4cos (30(t 8)° +18.T = the temperature in degrees celsius (in terms of the number of hours after midnight, 12 o'clock)t = 1 when it is lama) How many hours will the temperature be below 14°Celsius?b) What is the temperature (in school) at the end of the school day, 3pm?

When the Radius Increases a. A rope is wrapped tightly around a wheel with radius of 2 feet. If the radius of the wheel is increased by 1 foot to a radius 3 feet, by how much must the rope be lengthened to fit around the wheel? b. Consider a rope wrapped around the Earths equator. We noted in Exercise 17 that the radius of the Earth is about 4000 miles. That is 21,120,000 feet. Suppose now that rope is to be suspended exactly 1 foot above the equator. By how much must the rope be lengthened to accomplish this? The Size of the Earth The radius of the Earth is approximately 4000 miles. a. How far is it around the equator?
