According to newton's law of cooling, if a body with temperature t 1 is placed in surroundings with temperature t 0, different from that of t 1, the body will either cool or warm to temperature t(t) after t minutes, where: t(t) = t 0 + (t 1 - t 0)e kt and k is a constant. a cup of coffee with temperature 140°f is placed in a freezer with temperature 0°f. the constant k ≈ -0.0815. use newton's law of cooling to find the coffee's temperature, to the nearest degree fahrenheit, after 15 minutes. the temperature is about a0degrees fahrenheit.

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
