Answer:
Step-by-step explanation:
Given
at 9 am temperature of the body is 
1 hr later temperature 
Temperature of room 
According to newtons law
Integrating
Now at 9 am i.e. t=0,
At 10 am i.e. t=1 hr T=89
Temperature of Normal human body is 
Taking log both sides
i.e. 5 hr and 16.2 min
i.e. victim murdered at 3 am and 43.8 min
Y-int (0,4) because y=Mx+b, b is y-int
Slope is 2 means that the pattern of the graph is 2/1 up 2 over 1
60 minutes in an hour. 60-45=15
4:15

hope it helps
(sorry I didn't know how to explain it)
We have the following expression:
(2x + 5) * (7-4x)
Rewriting we have:
14x - 8x ^ 2 + 35 - 20x
Grouping terms with the same exponent:
-8x ^ 2 + x (14-20) + 35
Rewriting:
-8x ^ 2 - 6x + 35
Answer:
the quadratic expression for this is:
-8x ^ 2 - 6x + 35
