Answer:
Step-by-step explanation:
it is this graph
I think the answer is 10 since that is the largest number they can both be divided by
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)
Answer: -8.58
Explanation
we add -3.28+-9.7
-(12.98 - 4.4) = -8.58
Answer: 65.5 inches of the box is empty.
Step-by-step explanation:
Given : Diamter of circular pizza =10 inches
Then, radius =
Area of circle =
Area of pizza =
Side of square = 12 inches
Area of square = side x side.
Area of square = 12 x 12 = 144sq. inches.
Area of box empty = Area of square - Area of pizza
= 144-78.5 sq. inches
= 65.5 inches
Hence, 65.5 inches of the box is empty.
