On consecutive evenings a researcher sets the lights in a restaurant at 40, 60, and 100 watts, and has either music or no music, until all possible combinations are met. That is, on Monday the lights are at 40 watts, with no music (NM), on Tuesday the lights are at 40 watts with music (M), Wednesday 60 watts with NM, Thursday 60 watts with M, Friday 100 NM, and Saturday 100 M (hint: draw a matrix). She uses the same staff each night. At the end of each evening, she determines the total amount made in tips. What formal question is this experiment asking

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 104 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 105 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.
