Question 694395: Please help me write this equation.
Newtons law of cooling. The change in temperature of an object over time t, denoted T', varies directly with the difference between the temperature of the object T and the temperature of the surrounding environment, or ambient temperature, A. Letting -k represent the constant of variation for a positive value of k. Write the equation to represent newtons law of cooling.

Question 694401: Project help please. I do not understand this. Please explain.
Using calculus and the equation: T'=-k(T-A), a team determined the temperature of an object after time t in minutes is given by the formula: T(t)=A+(T0-A)e^-kt. The 0 by T is on the bottom of T. The T0 represents the temperature at a time t=0. Verify that the constant of variation can be found using the formula: k=1/t1 ln(T1-A/T0-A). The numbers behind the T's are little and at the bottom. Where T1 represents the temperature at some later time t1. Now verify that tn, n is little and on bottom, the time the engine stopped running at a normal operating temperature is given by : tn=1/k ln(Tn-A/T0-A), where Tn represents the normal operating temperature of the engine. Again the numbers and letters after t and T are little and on bottom.

Question 694510: I had a test of 46 questions: one question equaled 4 points, a second question had 5 parts worth 2 points each-got 2 wrong earning 6 points, a third question had 8 parts worth 2 points-earned 18 points
Of th remaining 43 questions,20 questions counted as 1 point- got 18 right and each-earned 18 points,of the remaining 23 questions-got 16 right counting 2 points each and earned 32 points
When I calculated how my grade added up to a 78, I realized that it was simply added as 18+32+4+6+18=78 score.
However, if I added in the 2-2 points questions I got wrong that would equal 4 additional points + the 7-2 point questions i got wrong that would be an additional 14 points + the additional 2-1 point questions I got wrong that would equal 2, It would be only 98 out of 100 (78+4+14+2=98).
If I had solved it my way I would have added the correct questions #44 equaling 4 points, #45 equaling 6 points and #46 equaling 18 points (14+6+4=28)and did the following calculation:
(1) 100%-28% = 72% of highest score remaining
(2) 72%/43 questions = 1.67 points per question
(3) 1.67 *34 = 57.8
(4) 57.8% + 28 = 86% score
Now I realize that if I tested the 100% challenge by calculating the 1.67 * 9 of the 43 question portion I got wrong, the totaling 15.03 would mean that the percent total would come to - 58 + 28 + 15 = 101
But couldnt we make #44 a 3 point question instead of a 4 point question bringing the totals to
57.8 + 27% + 15.03 totaling 99.83 = 100 rounded.
Even if it was decided to take the 86 down to an 85 to even things out would be fine with me. I'll take a 85(b) over a 78(c) anyday!
Questions:
Can I be graded on a 98 percentile? Seems a bit manipulated.
Is there a set way of calculating test scores NYS and would you know where I could look it up?
Do you have any advice on how to approach the situation? Those 2 point would mean the difference between a grade C and a grade B especially since the lowest grade would be moved up a grade.
Even though it could be decided to give different points for different parts of a test, should each part total to 100%.
How would you calculate this test if you using initial point system givin above to balance out the 100% high score.
How do I calculate (i.e. 32 is what percent of 100?) Cant seem to remember.
Please help!
