I need MathLab Code for this problems...I will give thumbs up for work.

Problem 36 (50pt). Sound level in units of decibels (dB) is determined by: L, = 20logie PO where p is the sound pressure of the sound, and p. = 20x10 Pa is a reference sound pressure (the sound pressure when L, = 0dB). (a) The sound pressure of a passing car is 80x10-2 Pa. Determine its sound level in decibels. (b) The sound level of a jet engine is 110 decibels. By how many times is the sound pressure of the jet engine larger (louder) than the sound of the passing car? Problem 37 (25pt). Use the Help Window to find a display format that displays the output as a ratio of integers. For example, the number 3.125 will be displayed as 25/8. Change the display to this format and execute the following operations: (a) 58 +1% (b) 73-11/3+2 +2.72
