Answer: B)

Step-by-step explanation:

If y = z then replace z for y in the second equation.

2 y + z = 12

2y + y = 12

3y = 12

y = 4

This also means z = 4.

Insert both of these values into the first equation:

x + y + z = 8 + 2sqr3

x + 4 + 4 = 8 + 2sqr3

x + 8 = 8 + 2sqr3

x = 2sqr3

A forensic detective is called to the scene of a murder at 2 am. When she checks the temperature of the body, she sees that it i

Newton's Law of cooling is
$T(t)=T_{a}+(T_{0}-T_{a})e^{-0.1947t}$
where
T(t) = temperature of the body after t hours, 80 °F
$T_{a}$ = ambient temperature, 65 °F
$T_{0}$ = normal body temperature, assumed to be 98.6 °F

The elapsed time since death is obtained from
$65+(98.6-65)e^{-0.1947t|} = 80$
$33.6e^{-0.1957t}=15$
$-0.1947t=ln \frac{15}{33.6}$
$t= \frac{ln(15/33.6)}{-0.1947} =4.142$

4.142 hours before 2 am is 9:52 pm (the previous day) approximately.

Answer: 9:52 pm the previous day.
