Entered Answer Preview Result 12.29 12.29 incorrect The answer above is NOT correct. (1 point) Suppose that u = 8xe% + 9y sin(42) and that x, y, and z can be measured with maximum possible errors of +0.04, +0.05, and ET/130, respectively. Use a linear approximation to estimate the maximum possible error in calculating u from the measured values x = 7, y = In 2, z = 7/8. Error in u is 12.29
