You need to display output for all of the values between the starting and ending values. First two values are temperatures in Fahrenheit. You need to display all of the values from the first temperature to the last temperature. You increment from one temperature to the next by the increment value (the third value you read in). You need to convert these temperatures to Celsius and Kelvin. You need to output the temperatures as Fahrenheit, Celsius, and Kelvin. The numbers should be 18 characters wide with 4 digits of precision and need to be in fixed format. Do not use tab characters (/t) to output the values.

Plot the function for. Notice that the function has two vertical asymptotes. Plot the function by dividing the domain of x into three parts: one from - 4 to near the left asymptote, one between the two asymptotes, and one from near the right asymptote to 4. Set the range of the y axis from - 15 to 15.

Suppose a person (height of 1.8 m) walks in a room installed with a pyroelectric infrared (PIR) motion detector. The distance between the person and the PIR detector is 5 m. The PIR detector sensor is 3 cm x 1 cm in size.

Estimate the radiated power at the surface of the sensor from the person. Assume that emissivity of human skin/fabric and sensor cap is 0.9. Assume that the person's body temperature is 37°C and the temperature at the surface of PIR detector is at 18°C. Also assume that there is no radiated power loss through air and Fresnel lens. You can roughly estimate surface area of the person.

Anesthesia induces muscle relaxation (paralysis) in the patient using a mixture of isoflurane and atracurium. An approximate model relating muscle relaxation to the percent isoflurane in the mixture is:

P (s) / U (s) = 7.63*10-2 / S2 + 1.15s + 0.28

where P (s) is a percent measure of muscle relaxation and U (s) is the percent mixture of isoflurane.

A. Find the damping ratio and the natural frequency of the paralysis transient response.

B. Find the maximum possible percent paralysis if a 2% mixture of isoflurane is used.

C. Plot the step response of paralysis if a 1% mixture of isoflurane is used.

D. What percent isoflurane would have to be used for 100% paralysis
