Answer:

4.05d+0.1i−4.2

Step-by-step explanation:

Let's simplify step-by-step.

1.6i+ 3/ 4 d−3( 1 /2 i−1.1d)−4.2

Distribute:

=1.6i+ 3/ 4 d+(−3)( 1/ 2 i)+(−3)(−1.1d)+−4.2

=1.6i+ 3/ 4 d+ −3/ 2 i+3.3d+−4.2

Combine Like Terms:

=1.6i+ 3/ 4 d+ −3/ 2 i+3.3d+−4.2

=( 3/ 4 d+3.3d)+(1.6i+ −3/ 2 i)+(−4.2)

=4.05d+0.1i+−4.2

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.
