Please solve 5.1 and 5.2! Please show all steps below

5.1 Determine the D value for the microorganism when given the following thermal resistance data for a spore suspension: Time (min) Number of survivors o 15 30 45 106 2.9 x 105 8.4 X 104 2.4 x 104 6.9 x 103 60 5.2 Plot the survivor curve on regular and semilogarithmic coordinates. The results of a thermal resistance experiment gave a D value of 7.5 minutes at 110 C. If there were 4.9 X 104 survivors at 10 minutes determine the ratio (N/No) for 5, 15, and 20 minutes
