1. Suppose Brett and Samantha each throw a baseball into the air. The height of Brett's baseball can be represented by the following equivalent equations, where h(t) is height in feet and tis time in seconds: h(t) = -16(t+ 0.1)(t-5) h(t) = - 16t2 + 78.4t+8 h(t) = -16(t-2.45)2 + 104.04 The height of Samantha's baseball is given by the graph below: |(2,64) 65 GO height (in feet) 55 45 25 10 time (in seconds) a. The two kids were interested in comparing their throws. Begin by analyzing the flight of Brett's baseball. What is the baseball's height after 3 seconds? Does it matter which of the three equations you use?

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.

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
