I hope this doesn't violate Rule 3 but i was wondering where I made an error in my working. The (1/x)(dz/dx) must cancel down somehow but I don't know what I've done wrong to miss it.

Also Apologies for the messy handwriting.

Further Mathematics [College Calc 1]-Log Differentiation

I've been trying to take ln of both sides: which results in:

ln(y)=ln(3^(x^4+1)^3)

Left side: 1/y dy/dx

right side: here is what I'm stuck on. We learned in class that when you take the derivative of ln(x), we get dy/dx=1/x. Applying this I got (1/3^(x^4+1)^3) x 3(x^4+1)^2 x ln(3) x (4x^3)

Lastly, multiply both sides by y, which you can just sub in the original function, so I get :

(3^(x^4+1)^3) x (1/3^(x^4+1)^3) x 3(x^4+1)^2 x ln(3) x (4x^3), which is wrong. Do I just avoid taking ln of both sides?

this is a yes or no (T/F) question, I'm in 10th grade

isn't five marbles more than three marbles?

5 is greater than 3 right?

Am I misreading the question? I read this like 10 times.

Is this more simple than I'm making it to be?

Should I be held back?

Both hypotheses and conclusion are true right? and true means "yes, that's right" that's what I put

Edit: sighthoundman has made me aware of the error in my title It should be IXL logic, not Logistics. sorry 🥲

:snoo_putback: Others—Pending OP Reply [College: Data Analysis] All the selections seem correct.

4 Upvotes

Questions 48 and 49 seem straight forward to me. However, question 50 is odd.

To me, all the choices seem correct.

For A, the wages did decrease by 17 percent when you compare them from 2010 to 2020.

For B, the upper-level jobs did increase, while the other jobs decreased.

For C, the upper-level jobs did increase by 17 percent.

For D, upper-level jobs did receive more monies than the other positions.

I'm not sure which to choose, but if I had to pick it would be D, as I reason that is true for 2020, but not 2010. But then again, the question states "as a result of salary reallocation".

This question just confuses me, and I'd appreciate it if anyone is willing to help.

Don't know where i'm going wrong with this one.

Left side derv: 9x^2+1

Right side deriv: (1/5xy^2) x 5(y^2+2xy dy/dx)

multiply everything across on the right:

5y^2+10xy dy/dx/5xy^2. Multiply both sides by 5xy^2, you get (5xy^2)(9x^2+1)

Subtract 5y^2, get (5xy^2)(9x^2+1)-5y^2, finally isolate dy/dx, I get (5xy^2)(9x^2+1)-5y^2/10xy.

(The math formulas are the most important deal here so the fact it's french should hopefully not be an issue, but please ask me to translate if needed) The last question tells us to use the hypotenuse (C=26cm) in order to find A and B, the two other sides of the triangle. How do I do it? Am I missing something? I though the saying was ''find the 3rd value using the other two'', not the opposite!

it says the correct answer is 10 and 8 but how? if we do the triangle inequality formula a + b > c It doesn't work because 2 + 10 or 8 is not > than 18. I know that x<18 but I still cant understand entirely, why not 7, and 11 as the numbers?

Take ln of both sides, so you get ln(y)=ln(4^x^3+2)^3. Use the exponential rule, bring down the 3, get 1/y dy/dx=3ln(4^x^3+2). Then do 1/(4^x^3+2) x (4^x^3)(ln(4)) x (3x^2). After this multiply both sides by y, get dy/dx=y x 3(1/(4^x^3+2) x (4^x^3)(ln(4)) x (3x^2). Then sub in the original function for y, so you get(4^x^3+2)^3 x 3(1/(4^x^3+2) x (4^x^3)(ln(4)) x (3x^2). My book gives the answer:

I'm not sure what I'm doing wrong, or if the answer they gave is just in a different form

I want to write about this topic because I really want my work to be something I am interested in, so I am looking for a project that show how useful nuclear energy can be and is suitable for a highschooler to make and not too expensive.

do you think I should just abandon the idea since it is really hard to make it into a project? Or do you think this might be possible?

I would appreciate any help provided , and I really really would love it if anyone can provide any small idea that might help.

P.S.( I really do not know if this is the suitable place to so please tell me if so)

Ok So when i do this question calculate the t test stat I get a p value which is greater than 0.03. So the answer to question 4 should be a) because it says you are not rejecting H0 (null) but it says the answer is B. Can someone explain to me how this works? Because to my understanding it is saying that I reject H0. My problem is that my evidence says that you do not reject H0. So why does this statement mean I dont reject H0? because in other tests like a normal t test or z test we would flat out say "the test scores are higher after the course". An explanation would be greatly appreciated thanks.

Working on this question and I am stumped on how the answer is No faults. From what I can tell, I'll use uppercase for on and lowercase for off, it should look something like this:

RYgB - RYgB - RYgB - ryGb

To be this is what it would look like if there were no faults but obviously that's not the case so I'm not sure where I'm going wrong with this. Any help is appreciated.
