Homework Help

Hi, I need help for problem 14. I don’t understand how to compare the second equation to the first so that I can answer in terms of F. Thank you.

Can anyone direct me to a summary of vitamin d and IBD? I’ve read so many articles and just looking for a summary

Let a 3 × 3 matrix A be such that for any vector of a column v ∈ R3 the vectors Av and v are orthogonal. Prove that At + A = 0, where At is the transposed matrix.

Hello I know how vitamin d is absorbed in the skin but looking how it is absorbed in the gi tract. The physiology. Can anyone explain to me or point me to some resources. Having a hard time finding some.

Fungi are a separate branch of the evolutionary tree to my understanding, how to they differ from the different branches? How are they the same? How does point of original effect how a fungi behaves? How has human interaction effected fungi evolution over time?

Hello there! I'm currently working on a research topic. I just need a deeper information about the properties of compounds, how do they are similar in character, how they can do certain things when combined. More like I want a book concerning on processes of how compounds can do. "Just like a cook book of chemicals' lol Please help me to study that will really a big help!

Hello sir How to solve this The region of DNA sequence that provide binding site for RNA polymerase is: 1. Terminator 2. Structural gene 3. origin sequence 4. promotor

What is Reaction mechanism of sodium hydroxide, ethanol and stearic acid?

Hi everybody! The last expression was derived by converting an underdamped harmonic oscillation to a travelling wave. Actually, I searched everywhere and I did not find such expression (it can be also wrong). The loss factor (l) and the wave number (λd) are replaced by an expression depended by the damped frequency. Although in most applications the damped frequency is calculated and not used as input (as the loss factor) to the expression, could the last expression be a valid solution for the underdamped wave equation when the initial frequency (ω0) is known? Or is the wavenumber correct for the damped wave expression?

I making some research, about effects of household antibacterial regents on bacterial colonies. So I grow bacterias from desk before regent was used and after. And problem that my stupid head thought let use grama staining method, now I have 8 photos from microscope and I need compere number of bacterias from each sample. Can someone can recommend program or method how count cells and give some tips how next time don’t make similar mistake, recommend methods to count cells (I don’t have expensive lab technologies). Can I somehow adapt this man's program? Also adding some photos from research: https://imgur.com/a/NK757e4

C(s, graphite)+H2(g)+O2(g)⇌CH3OH(l);∆Ho=−238.7kJ What would increase the value of Keq?

I’m really stuck on this problem. This involves the dissolving of Borax. Na2B4O7•10H2O(s)<->2Na^+(aq) + B4O7^2-(aq) + 10H2O deltaH=109kJ/mol deltaS= 340J/mol•K Kc=0.047@25C If the starting concentration of B4O7 is 0.17M and the sodium ions are 0.34M at 25C, which direction will the reaction proceed? I said forward because Q At what temperature would a mixture of these same starting concentrations be a saturation solution (i.e. be at equilibrium) And that’s where I’m stuck At what temperature would a mixture under standard conditions (B4O7=1M, Na=1M) be a saturation solution (i.e. be at equilibrium) And I’m stuck here again …

I have attached the question in a file to this post. I am taking an online calc 1 course and I am struggling with this concept of continuous and discontinuous functions. I know the answer to this question is b, but I do not understand why. I've spent a couple hours (yeah :( ) on trying to understand this problem but I STILL DON'T GET IT. Can someone explain it to me? Online videos are unhelpful and my textbook is not doing it for me.

How to find the volume of irregular object? Help me , please Thanks in advance

PLEASE HELP... thanks for any help.

Hi, I'm trying to solve the below equations, M7 and L7 are unknown ( I'm trying to get here : L7=(equation without M7 ) and M7=(equation without L7 )). I spent a lot of time without success any help will be highly appreciated. 1) R=I7-M7*COS(RADIANS((90-K7)+L7))+J7*SIN(RADIANS(90-K7)) 2) S=H7-M7*SIN(RADIANS((90-K7)+L7))-J7*COS(RADIANS(90-K7)) Thanks in advance.

The house was bought for $500 and sold for $ 700 , find the percentage profited that they got ? I just can't get my head around to find the% profit. Thanks for any help

I had some difficulty , with this problem in class yesterday. I don't know where to begin with. Thanks

So I used a Fitbit Versa to measure my heart rate for a science experiment and I need to record the uncertainties in my report. How can an uncertainty for measuring the heart rate with a Fitbit be determined? Is it something I can calculate with my data? Thanks.

3x=21 Solve for x Can you please explain to me, because I missed this topic when we did in school. Thanks

this is not an assignment I was given but it is something I've been thinking about and I don't know how to solve it I want a list of equations that use two variables that when I plug in any whole number value for the two variables they will give me solutions to the equation (a^2) + (b^2) = 2(c^2) an example of what I want is the Pythagorean triples. (a^2) + (b^2) = c^2 a = 2mn b = (m^2) - (n^2) c = (m^2) + (n^2) can someone help me with this problem?

Good day to everyone reading this. Thanks for your time. I've got this question here (more like an research assignment) which requires me to predict further values in a given set of values. I've attached a picture for a better understanding. The data is the cases of influenza in a country over the years. There's values missing in from May, 2019 onwards. We have to use the previous set of data, come up with a "Prediction model" and use that to predict the values until end of 2019. The thing is, our teacher is very incompetent, and only told us to use "polynomials from the graphs we make in excel" and use that... Anyone got any clues/hints on how i could come…
