Fox population problem: naturalists find that populations of some kinds of predatory animals vary periodically with time. assume that the population of foxes in a certain forest varies sinusoidally with time. records started being kept at timet0 years. a minimum number of 220 foxes appeared when t3.1 years. the next ma 2. a. sketch the graph of this sinusoid. b. find a particular equation expressing the number of foxes as a function of time. c. predict the fox populatin when t = 7 ,o, 9, and 10 years etween what two nonnegative values of t were the foxes first endangered? show on your graph in part a that your answer to pard d is correct. e.

The minimum wage in washington has been increasing over the last ten years. years 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 washington state minimum wage $6.50 $6.72 $6.90 $7.01 $7.16 $7.35 $7.63 $7.93 $8.07 $8.55 $8.55 a) find the linear regression equation for the minimum wage in washington using this data ( x  0 in 2000). round to the thousandths. b) what is the slope? specifically, what does the slope represent in the real world context? c) what is the y-intercept? specifically, what does the y-intercept represent in the real world context? d) write your equation as a function of x. e) if you do not earn a college degree and you are earning minimum wage in 2020, what do you predict you will be earning per hour with the linear regression equation? f) if the trend continues, when will the minimum wage be $15 an hour? 3. why are your answers to #1d and #2a above different? which do you think is more accurate (#1 or #2) and why
