I need the answer to question 8. I have the answer to 7 but number 8 is based off of 7. Thank you so much

7. (1 mark) When discovered, the temperature of a dead body was 21 .C and the ambient temperature was a constant 19 .C. The body was quickly taken to the morgue where an experiment was performed to compute k = 2 hr-. Note that the normal body temperature is 37 .C and the formula for the cooling of a body is given by T(t) ATA+ (To -TA)e-kt. The number of hours that the body had been dead is given by: In b ) In c) In d) in e) Ing a Ob Oc Od Oe Question 8 (1 point) 8. (1 mark) In the question above, suppose instead that a new k is computed i.e. the body was instantly taken to the morgue (at 21 .C). After three hours, it cooled to 14 .C, where the ambient temperature at the morgue was 4 .C. The value of k is given by: a) b ) In 12 c) 10 d) 19 e) In 10
