When someone purchases a new car and begins to drive it, generally speaking, the resale value of the car (in dollars) goes down each year. Let represent the number of years since purchase and represent the resale value of thecar (in dollars). The linear function that models the resale value based on the number of years since purchase is y = 32000 - 3500x. What can we say about the rate of change and the initial value? Answer fast please 25pts. multiple choice.

A. The rate of change is 32000 and the the initial value is -3500. $32000 represents the decrease of value per year and -3500 represents the initial value of the car.

B. The rate of change is 3500 and the initial value is 32000. 3500 means that the car increases its value by $3500 every year and the initial value is $32000.

C, The rate of change is -3500 and the initial value is 32000. -3500 represents the initial value of the car.

D. The rate of change is -3500 and the initial value is 32000. 32,000 represents the initial value of the car and -3500 is the decrease in value of the car every year.

Acable company wants to provide cell phone service for residents on an island. the function for the cost of laying the cable from the island to the mainland is c(x)= 6.500 square root x2+4, where x represents the length of the cable in feet. what are the domain and range of the function? a) domain: all real numbers range: all real numbers greater than or equal to 17,000 b) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 17,000 c) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 13,000 d) domain: all real numbers greater than or equal to 13,000 range: all real numbers greater than or equal to 0

Gabriel determined that his total cost would be represented by 2.5x + 2y – 2. his sister states that the expression should be x + x + 0.5x + y + y – 2. who is correct? explain.

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.
