Aditya's dog routinely eats Aditya's leftovers, which vary seasonally. As a result, his weight fluctuates

throughout the year.

The dog's weight W(t) (in kg) as a function of time t (in days) over the course of a year can be modeled by

a sinusoidal expression of the form a. cos(b. t) + d.

Att = 0, the start of the year, he is at his maximum weight of 9.1 kg. One-quarter of the year later, when

t = 91.25, he is at his average weight of 8.2 kg.

Find W(t).

t should be in radians.

W(t) =

If your teacher tells you to do questions 6 through 19 in your math book for homework, how many questions is that

What is the x-intercept and y-intercept of the equation 2x+1. 2o

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
