Consider the following function: Interval f(x) = 3 / (x^2 + 4), [-8, 8]. Discuss the continuity of the function on the closed interval. The function is continuous on the interval(s). If there are any discontinuities, determine whether they are removable. There is a removable discontinuity at x = -8 and x = -4. There is a nonremovable discontinuity at x = 4 and x = 8. There is a removable discontinuity at x = -8. The function is continuous on the entire interval. There is a nonremovable discontinuity at x = 3.

2 Midterm 1 An engineer is shopping for a temperature sensor with a certain response time. One temperature probe is shaped like a cylinder of some unknown diameter and a length of 10 cm. The probe is made of chromel, with properties listed in the table below. The temperature probe is advertised as having a response time of $0.65$ s. The engineer plans to use the probe in a system with $h = 565 \text{ W m}^{-2} \text{K}^{-1}$. Determine the diameter of the probe. Is it reasonable to assume the probe will be at uniform temperature across its cross-section? Property Value Density, $\rho$ 8500 kg m$^{-3}$ Specific heat, c 440 J kg$^{-1}$ K$^{-1}$ Thermal conductivity, k 19 W m$^{-1}$ K$^{-1}$
