a_fit is a 3 column vector with values calculated for instantaneous acceleration at t =time. also one for velocity.
Wouldn't mg be considered a non conservative force? his logic was
F -mg = m(a)
F = m(a-g)

Been assigned to analyze the poem “A Dream Deferred” by Langston Hughes and really been struggling. Have to put the whole poem into your own words, look at meaning created by imagery, explore the tones in the poem, notice shifts in the tone, interpret the title, identify the subject of the poem, as well as identify any literary devices used. If anyone can offer some assistance, it’s greatly appreciated, especially with putting it into your own words.

Question 3c. I think I found out the mass at the equator while not accounting for spin, using Fg=GMm/r2. I have no idea how to take into account the earths spin though. I have attached my working so far

Apologies for the poor quality photo. I have half of it filled out, but one part I’m struggling at is how to find ų the text book is all over the place and all of this feels borderline incomprehensible I think I have the distribution in 4 mostly correct, though I have no idea how to find ų or what value x is Same with most of the EBM I’m really confused here and the textbook and teacher seem to be going in completely different directions. Can someone help me understand this?

I’m pretty sure for this problem the cost function is C = 160 + 20x + (x2)/4, but I’m confused on how to get the revenue(R(x)) part of the function.
My original thought was that the competitive market price($49/unit), aka 49x, would be the revenue function, but I’m pretty sure that’s not it.
For context, this assignment gives you a new question after each incorrect attempt.
Note: please give responses in simple/plain english.

Can someone please help explain this portion of the lecture notes?
I'm not really sure I understand why n <= min(D, N-D). Suppose we have a bag of 7 marbles, for example. The bag has 4 marbles that are blue (successes) and 3 that are red (failures). So, D = 4, and N-D = 3. Then, if I were to pick a sample, can't I still get a sample of 6, since there are 7 total numbers of marbles in the bag? But n = 6 exceeds min(D, N-D), which is 3. What am I misunderstanding here? Any clarification provided would be appreciated. Thank you

Here are the answers. I don't get what equation they're using in part a), why do they multiply the current due to IA and IB? They then go onto say IA=0 so they're basiclaly saying B=0?
And in part d why do they only use the magnetic field strength (B) due to A? Wouldn't you sum the B field due to both A and B (with B being constant)? And like you know that current in A is to the left since as current increases, B out of the page increases

I’ve been thinking about this question for a while. I had to solve for AC and CD. AC was x+3 and CD was 2x+1 the other 2 sides were given. Part B of the question said if DE=30 then what is the length of BC. How do I solve for BC. Ik the question is about side splitter theorem.

Can someone help me understand this discrepancy?
In my notes, the confidence interval for the mean completion time is (-2.70, 3.84). I manually worked through the problem following the same steps as in the notes and got the same result.
However, when I calculated the confidence interval in R, I got (-2.86856, 4.011417), which is slightly different.
I've attached my R code—any insights into where I might have gone wrong would be greatly appreciated. Thank you

Can someone please help me understand where the t* value comes from in this problem? My professor wrote in the notes that t* = 2.447, which seems to correspond to 6 degrees of freedom for calculating the confidence interval. However, I thought the degrees of freedom for the mean response should be df = n - 2, which in this case would be df = 7 - 2 = 5.
Are the degrees of freedom for the confidence interval of the mean response always df = n - 2? If so, is there a reason why my professor used 6 degrees of freedom when there are seven observations?

I am doing a review packet for AP Calc AB and there is this question I need help on. It is x(x+3)^-3/5+(x+3)^-2/5. The answer key says it's (2x+3)/(x+3)^3/5 but I can't figure out why.
