What service converts ip addresses into more recognizable alphanumeric names? ?

Alook-up table used to convert pixel values to output values on a monitor. essentially, all pixels with a value of 190 or above are shown as white (i.e. 255), and all values with a value of 63 or less are shown as black (i.e. 0). in between the pixels are scaled so that a pixel with a value p is converted to a pixel of value 2/127 −+3969). if a pixel has a value of 170 originally, what value will be used to display the pixel on the monitor? if a value of 110 is used to display the pixel on the monitor, what was the original value of the pixel?

Which of the following is true of operations within a spreadsheet program’s built-in functions? a. operations within parentheses, then multiplication and division, and then addition and subtraction are computed. b. operations within parentheses, then addition and subtraction, and then multiplication and division are computed. c. multiplication and division, then addition and subtraction, and then operations within parentheses are computed. d. addition and subtraction, then multiplication and division, and then operations within parentheses are computed

Using least squares fitting, you are to fit the data sets to the following models and solve for the parameters ai , where i is the index of the parameter. the input/output data for the systems are linked in the bblearn site. for each of the systems use matlab to plot the supplied data vs. the model fit on one plot. include your code in the solutions. (a) linear fit "lineardata.mat" y=a1x^3 + a2x^2 + a3x + a4 (b) plant fit "plantdata.mat g(s) = a1/(s + a2)
