Answer:
line p matches with the first equation
Step-by-step explanation:
T(t)=e−kt(∫ekt[KM(t)+H(t)+U(t)]dt+C)
M is the outside temperature, H is other things that affect temperature
in the tank(0 in this case), and U is the solar panel. K comes from the
time constant, and should be the inverse of the time constant I believe.
T is temperature, t is time.
T(t)=e−164t(∫e164t[164(80)+4t]dt
After integrating I keep getting
−16304+256t+Ce−164t
I calculate C to be 16414 setting t equal to 0 and using the initial conditions
1. 6:2 or 3:1
2. 8:6 and 16:12
3. 26:35 (I think )
4.0.25mile:1 min
Answer:
5 months
Step-by-step explanation:
Given
Required [Missing from the question]
At what month will the cost be equal
To do this, we equate both expressions
This gives:
