why does the rate changing between periods bother you. Let me guess you still haven't looked up "first order system".
Do you realize that you are embarrassing yourself.
how many data points does one need to find the unknowns in an exponential response.
Y(t) = K*(1-exp(-tau*t))
Huh dum dum ...
You say nothing to prove yourself any better. Just idle insults and inane blabber. Tell me what is wrong with the question in detail if you claim to have any ability. And first there IS a difference between a "first order model" and "first order system" look it up on Google before you reply. So far I think a third party would justly conclude you are mouthy blowhard who is incapable of feeling shame.
It's a simple case of finding the best time constant for the solution given the measured points. Then solving for the time at which the system will be at 160F. Hawfaeces has answered so we have 1 fail and 0 correct.
Do you find it ironic that you cast insults about math ability while clearly failing to understand much less answer the question in the same thread. I am done with you on this one, you failed yet again. I will give others some chance and then post the answer.
No backtracking you moron.
the problem stated "first order system"
You misunderstood the problem due to lack of knowledge.
The problem is very well posed for anyone who has had freshman calculus.
I don't think you ever got an engineering degree. You confused two things.
"first order model"
"first order system"
If you have no clue why don't you refrain from posting. You always but in and fill my sat night math problem posts with inane garbage. Let someone else who has a clue give the answer.
Well I see you don't think the conduct of a brother is relevant but you do think that every fault of anybody president Obama has ever spoken to IS a reflection on him.
why did you type out that long post and still not even try to solve the problem. It's likely you don't have enough basic skills to even understand the problem. Anybody else wanna take a stab.
I'll give hints if asked.
Andrew was cooking a beef roast in the oven while his neurotic father David was screaming about when it would be done in the background. Andrew was taking meat thermometer temperatures every 20 min because his nerves were on their last leg due to his elderly fathers incessant yelling.
He realized that checking the temp so often made the whole cooking process take longer due to the opening of the oven. He also remembered some math from his college days and decided to estimate the done time of the roast considering the temperature at the meat thermometer in the center of the roast to be a first order system driven by the oven temperature.
Supposing Andrew was correct to model the cooking process as a first order system relating the oven temperature to the meat temperature at the tip of the embedded thermometer, how long will it take for the roast to reach 160F given the initial temperature out of the fridge was 35 deg and the first reading at 50 min cooking time was 80F and the second reading at 100 min cooking time was 116F. How much longer does he have to endure his fathers abuse before the roast is ready for the savage old coot to get his grubby fingers on it as it was cooked to an internal temperature of 160F.

""After 70 years we have forces in Germany and Japan, after 60+ years we have forces in South Korea.""
Not for the purpose of stabilizing those governments idiot.
He didn't have to. Wise men and women told him the whole en devour was a waste of time,money, and blood. Therefore proof is that 10 years on we still had to maintain force there. Obviously it was a failure even before our President decided wisely to cut the losses.
Maybe not those particular 4. But what good is the substitution of 3000 dead ones lost in war for the same result.
Or maybe... just maybe the whole region would not be so fackedup if boosh had not decided to westernize two middle eastern countries.
Milk on the floor is not the fault of the person who tried to clean it up but lies with the one who spilled it in the first place.
first thank GWB for #$%$ up the middle east and creating ISIS. Many unnecessary have died thanks to that brilliant insight.
Not really. You fail to get the truth that preventing unwanted pregnancies from delivering is certainly a cost savings over having to provide social services for years to a child not given enough to succeed.
Given your preferred alternative which is open devastating warfare a little carrot to go with the stick just might be a good move. No of course you don't understand.
