The solution to the initial value problem below takes on different forms for different ranges of the parameter ζ, which is called the dimensionless damping coefficient. In each case, write the solution in the suggested form. u'' + 12 ζ u' +36u = 0 u(0) = 0 u'(0) = 1

In two or more complete sentences, formulate how to use technology to calculate the appropriate regression model for the given data. you are not required to find the model, just choose the appropriate regression and explain how to use the technology.

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
