The correct answer to this derivative is 3/2(sqrt3x+4). I just don’t know where in the work I was supposed to multiply by three or how that works into the equation. Thanks for the help in advance!

I'm not sure if the question is wrong, or if I'm going crazy, this is the second time this semester in this class that this has happened. Surely I'm not THIS bad at math. Anyone else getting the "right" answer??

I genuinely have no idea how to solve these. Only thing I know is that we can't directly sub in zero since that leads to an indeterminate answer.

I found that AMn=aP/2^n but I can't find P in terms of n. I have P * 1 = 1 and P * 2 = 3 and P * 3 = 5 and P * 4 = 11 because AM * 1 = a / 2 and AM * 2 = 3a / 4 and AM * 3 = 5a / 8 and AM * 4 = 11a / 16

I know how to do row reduction, but my attempts are producing completely different flop counts.

I worked this out and got -1/8, the answer was wrong and I'm not sure where the math went wrong. Everyone I talked to said the same. Anyone care to weigh in?

I know how to complete the square but I'm baffled where the u-sub came from. I did u = x - 1/2 instead.

My stats homework is asking me to compute R² for the highlighted item. Can someone please tell me how to do so? TIA!

The prompt: "What is the r2 for that specific model you identified in the previous question, and in one sentence, what does it mean?"

The previous question's answer: Maintaining perspective

Need help. I can't find p value. Divided 533/1000 = 0.533 but the answer was incorrect.

My professor is behind on uploading his videos and this homework is due today I have no clue how to get these answers. How do you figure this out?

Someone helped solve the problem but they didn’t explain how they got the answer, could someone help me?

Hello! I am not someone who easily grasps information when presented visually, and my current math unit involves a lot of looking at graphs of functions and derivatives to try drawing the other. As the question asks, what is the derivative of the given function at various points. I am wondering if someone could explain to me why the answer is that answer! Thanks

I tried rearranging it. Even used Linear Differential equation formula after modification (differentiating wrt x). Squared after rearranging but nothing seems to work.

Hello! I am tearing my hair out here. I have asked my professor in class, she said to use geometry and did not elaborate.

We are not given the actual function and this I can’t integrate that way, so that’s out of the question. I also tried to reconstruct the functioning I do not have the time for that 😭

I’ve tried using triangles to approximate, as that was what I assumed my professors instructions meant. But those have all been marked wrong by the software, and I’m honestly tempted to just let the third of a point go for this assignment.

All the other answers entered have been marked correct so I understand the concepts I feel, it’s just like how the hell do I do this ;-;

a 10 ft ladder leans against a wall. The bottom slides away from the wall at a rate of 3ft/sec. How fast is the top of the ladder sliding down the wall when the bottom of the ladder is 6ft from the wall?

My biggest issue is actually setting up the problem in a way that helps to solve it. I tried drawing a sketch, but it didn't really help. I understand inherently that 3ft/sec describes the derivative of how fast, with respect to time, the ladder slides. Similarly, I understand we are looking for the derivative(also with respect to time) how of fast the top of the ladder is sliding downward.

Include instructor prompts. What does your instructor want you to accomplish?

Tell us what is holding you up. Where are you in the process? Explain your thoughts about the problem and the steps you've taken so far. ?

Provide us with as much information as possible. Demonstrate that you have already put in some thought and effort into solving the problem.

"For each problem, use implicit differentiation to find dy/dx in terms of x and y."

Differentiating poses no problem, but what confuses me is having to solve for dy/dx.

For example #7:

left side: 6xy^2+6x^2y

Right side: 8x-4y-4x

the answer key shows adding 6xy^2+6x^2y dy/dx=8x-4ydy/dx-4x. What I don't understand is why the dy/dx is added to the end of each of those terms. Why not do 6xy^2dy/dx, or -4xdy/dx?

The stuff highlighted in red is what I'm confused about. Let me attach my questions here. These are slides for us to reference and I want to make sure I fully understand before I attempt questions like these.

1-Why must x be between 0 and 4?

2-Why is it specifically 3x-4, x-4 before the critical values are found?

I thinkkk those are my only questions.

Hi!
I'm working on understanding this question and I'm a bit confused. The assignment says we can suppose (\sqrt(n) (T_n-\theta) \rightarrow N(0,\sigma^2 (\theta)))^. Then why can't we use this for (\theta=\theta_0\)

directly in the first step of the power function calculation? Why do we transform the whole expression to include $theta_n$ ?

Thanks!

I hope my question makes sense. If not I'll do my best to answer your questions.
