- Finding Transition and Coordinate Matrices In Exercises 3740, a find the transition matrix from Bto B, b find the transition matrix from Bto B, c verify that the two transition matrices are inverses of each other, and d find the coordinate matrix [x]B, given the coordinate matrix [x]B. B={(2,2),(6,3)}, B={(1,1),(32,31)}, [x]B=[21]arrow_forwardWritingIs it possible for a transition matrix to equal the identity matrix? Explain.arrow_forwardAdvance Linear Algebraarrow_forward
- Correlations The study of U.S. cities in Exercise25 found the mean January Temperature (degreesFahrenheit), Altitude (feet above sea level), and Latitude(degrees north of the equator) for 55 cities. Here’s thecorrelation matrix: a) Which seems to be more useful in predicting JanuaryTemperature—Altitude or Latitude? Explain.b) If the Temperature were measured in degrees Celsius,what would be the correlation between Temperatureand Latitude?c) If the Temperature were measured in degrees Celsius and the Altitude in meters, what would be the correla-tion? Explain. d) What would you predict about the January Temperaturesin a city whose Altitude is two standard deviationshigher than the average Altitude? Jan. Temp Latitude AltitudeJan.

Create an m-file called exercise3_first name_last name.m Create the variable delx = "; 100 Create the matrix x = (0: delx: 8n) Create a second matrix called y = cos(2x); You're going to create a numerical approximation to the derivative of y (2x). Create the matrix dy by giving the function diff your matrix y. Your last step is to create the matrix dydx by dividing dy by delx. Graph x vs. y in red dots. Graph the derivative in black dots. To graph it, you'll have to use x (2: end). That's because diff returns a matrix with one less element. So, you can't use x, it has one too many values. Calculate the true derivative by hand and graph it in green dots. Add a legend, title, x label, and y label. You don't need units in the labels. Answer the following question using the disp () function. As Ax gets smaller, should the approximation get better or worse?

Assuming the fee for exchanging dollars to theseunits reduces the national currency returned perU.S. dollar by 5%, place the data in a matrix anduse a matrix operation to find the currency unitsactually returned per dollar. b.
