According to a popular, but untrue, urban legend, oceanographers have discovered images of giant pyramids made of crystal-like substances deep in the ocean. Suppose one of these imaginary pyramids has the dimensions shown at the right.
The volume V of a pyramid is 1/3 Bh where B is the area of the base and h is the height of the pyramid.
Part A
Find an equation that represents V in terms of x. Then find x in terms of V. Write your equation for x in
rational exponent form, and rationalize denominators where necessary. Show your work
Part B
Suppose a pyramid has a volume of 2,000,000 m^3. What is the height x of the pyramid? Show your
work
Part C
Suppose the urban legend were true, and a contractor could be hired to raise one of these pyramids and bring it to the surface of the ocean The estimated cost of the operation c(x) is $200,000 per meter of pyramid height with an additional cost a(v) of $300 per cubic meter of pyramid volume. What is an equation that represents the total retrieval cost t for a pyramid of any volume with these proportions in terms of x? How much would it cost to excavate this pyramid? Show your work.

Me on this one i will give you 20pts. answer should be in detail . this is the discussion topic. one of the most fiercely debated topics in sports is the hot hand theory. the hot hand theory says that success breeds success. in other words, rather than each shot a basketball player takes or each at-bat a baseball player has being an independent event, the outcome of one event affects the next event. that is, a player can get hot and make a lot of shots in a row or get a lot of hits in a row. the hot hand theory, however, has been shown to be false in numerous academic studies. read this article, which discusses the hot hand theory as it relates to a professional basketball player. state whether you agree or disagree with the hot hand theory, and give reasons for your opinion. be sure to use some of the terms you’ve learned in this unit, such as independent event, dependent event, and conditional probability, in your answer.
