Answer: He was killed 24.83 hours before the body was found.
Step-by-step explanation:
Since we have given that

Here, T is the temperature of a body t hr after death, T = 82°F
T₀ is the air temperature , T₀ = 67°F
T₁ is the body temperature at the time of death = T₁ = 98.6°F
So, we will substitute all the values in the above equation.

Hence, he was killed 24.83 hours before the body was found.
check the picture below.
so red line of BD is perpendicular to AC, hmmmm let's firstly find the slope of AC, bearing in mind that perpendicular lines have <u>negative reciprocal</u> slopes.
![\bf A(\stackrel{x_1}{-4}~,~\stackrel{y_1}{-2})\qquad C(\stackrel{x_2}{18}~,~\stackrel{y_2}{-8}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-8-(-2)}{18-(-4)}\implies \cfrac{-8+2}{18+4} \\\\\\ \cfrac{-6}{22}\implies -\cfrac{3}{11} \\\\[-0.35em] \rule{34em}{0.25pt}](https://tex.z-dn.net/?f=%5Cbf%20A%28%5Cstackrel%7Bx_1%7D%7B-4%7D~%2C~%5Cstackrel%7By_1%7D%7B-2%7D%29%5Cqquad%20C%28%5Cstackrel%7Bx_2%7D%7B18%7D~%2C~%5Cstackrel%7By_2%7D%7B-8%7D%29%20%5C%5C%5C%5C%5C%5C%20slope%20%3D%20m%5Cimplies%20%5Ccfrac%7B%5Cstackrel%7Brise%7D%7B%20y_2-%20y_1%7D%7D%7B%5Cstackrel%7Brun%7D%7B%20x_2-%20x_1%7D%7D%5Cimplies%20%5Ccfrac%7B-8-%28-2%29%7D%7B18-%28-4%29%7D%5Cimplies%20%5Ccfrac%7B-8%2B2%7D%7B18%2B4%7D%20%5C%5C%5C%5C%5C%5C%20%5Ccfrac%7B-6%7D%7B22%7D%5Cimplies%20-%5Ccfrac%7B3%7D%7B11%7D%20%5C%5C%5C%5C%5B-0.35em%5D%20%5Crule%7B34em%7D%7B0.25pt%7D)

so we're really looking for the equation of a line whose slope is 11/3 and runs through B(4,4). Keeping in mind that
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
