Answer:
53.3324
Step-by-step explanation:
given that a thermometer is removed from a room where the temperature is 70° F and is taken outside, where the air temperature is 40° F.
By Newton law of cooling we have
T(t) = 
where T (t) is temperature at time t,T =surrounding temperature = 40, T0 =70 = initial temperature
After half minute thermometer reads 60° F. Using this we can find k
So equation is
When t=1,
we get
The volume formula is area of base×height. In this case, we are working with rectangles, so the formula is l×w×h. We have to find the volume of each block and add them together. Top rectangle: 12×30×4=1440. Middle rectangle: 30×36×4=4320. Bottom rectangle: 30×60×4=7200. 7200+4320+1440=12960 inches squared.
Answer:
these are fromeast to greatest
9^10

Answer:
1/2
Step-by-step explanation:
Pick two points on the line
(0,-4) and (2,-3)
Using the slope formula
m = (y2-y1)/(x2-x1)
= (-3 - -4)/(2 -0)
(-3+4)/(2-0)
1/2
The constant rate of proportionality is 12!
