Answer:
range means finding the slope value of the graph. :)
Answer:
−7
Step-by-step explanation:
<em>Add- </em>
0.859+1.63=2.489
<em>Subtract-</em> (Not sure where the decimal was)
0.859-0.03=0.829
0.859-00.3=559
<em>Multiply-</em>
0.859*10^1=8.59
0.859*10^2=85.9
0.859*10^3=859
0.859*10^4=8590
<em>Divide-</em>
0.859/10^1=0.0859
0.859/10^2=0.00859
0.859/10^3=0.000859
0.859/10^4=0.0000859
<em>Round-</em>
0.9
0.86

Hope this helps. Have a nice day. May it be filled with joy and happiness. Please, stay safe and wash your hands. Happy Holidays.
Newton's law of cooling states that under forced convection (which is assumed to be true), then
dT(t)/dt = -k(T(t)-Ta)..............(1)
T(t)=temperature
Ta=ambient temperature=40F
k=cooling constant = 0.1947
T(0)=98.6F (assuming victim did not have fever)
Integrate (1)
T(t)-Ta=(T(t)-T(0))e^(-kt)
Solve for t
(T(t)-Ta)/(T(t)-T(0)) = e^(-kt)
take log:
-kt=log_e((T(t)-Ta)/(T(t)-T(0)))
substitute T(t)=80F, Ta=40F,T(0)=98.6F
-kt=log_e((80-40)/(98.6-40))=-0.38186
t=0.38186/0.1947
=1.96, or almost 2 hours (assuming k=0.1947 is in hours)
Not really understanding the question, more info?
