Consider the initial value problem dy dt = −t + (t 2 + 4y) 1/2 2 , y(2) = −1. (a) Verify that both y 1 (t) = 1 − t and y 2 (t) = −t 2 /4 are both solutions to the initial value problem. (b) Explain why the existence of two solutions doesn’t violate the uniqueness part of the existence and uniqueness theorems discussed in class. (c) Show that for any c ∈ R, the function y(t) = ct + c 2 is a solution to the differential equation for t ≥ −2c; that if c = −1, then the solution y(t) satisfies the initial condition, and that in this case y(t) = y 1 (t); and that there is no choice of c that makes y(t) equal to y 2 (t)

The map shows the location of the airport and a warehouse in a city. though not displayed on the map, there is also a factory 112 miles due north of the warehouse.a truck traveled from the warehouse to the airport and then to the factory. what is the total number of miles the truck traveled?

(c) compare the results of parts (a) and (b). in general, how do you think the mode, median, and mean are affected when each data value in a set is multiplied by the same constant? multiplying each data value by the same constant c results in the mode, median, and mean increasing by a factor of c. multiplying each data value by the same constant c results in the mode, median, and mean remaining the same. multiplying each data value by the same constant c results in the mode, median, and mean decreasing by a factor of c. there is no distinct pattern when each data value is multiplied by the same constant. (d) suppose you have information about average heights of a random sample of airline passengers. the mode is 65 inches, the median is 72 inches, and the mean is 65 inches. to convert the data into centimeters, multiply each data value by 2.54. what are the values of the mode, median, and mean in centimeters? (enter your answers to two decimal places.) mode cm median cm mean cm in this problem, we explore the effect on the mean, median, and mode of multiplying each data value by the same number. consider the following data set 7, 7, 8, 11, 15. (a) compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = (b) multiply 3 to each of the data values. compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = --
