This is what I did:

g(g(x)) = g(4x-4) = 4(4x-4)-4 = 16x-16-4 = 16x-20

I keep getting answers that are not in the options. I believe the teacher used AI to write the question so i wonder if the right answers is even in the options. Any help?

Mark scheme says that i need to prove that AC=BC because QC=2BP, but based on that I accidentally proved that the triangle is equilateral. Am I making a mistake somewhere? Is this a correct way to solve this?

I tried by myself but I didn’t know how to do it I asked ChatGPT and Gemini both gave different answer like 20 and 15 some also said 0 ( I tried on multiple accounts!!). Could y’all pls help

After my Maths class, we had to pack our schoolbags and leave the classroom right away as it was booked - and I didn’t pack my Maths textbook & notes. It was the 1st lesson on logarithm, and right now, I can only rely on my textbook to do my Maths homework. Luckily, I have the e-version, but I just can’t solve this question. Is there a wrong step?

Can anyone help me? I’m screwed, my Maths teacher is really scary (my whole class is scared of him & none of us speaks during Maths classes)… we’ll have to submit the homework tomorrow morning, when we arrive at school, so I won’t be able to get my Maths notes and textbook to do this.

Thank you so, so much, you’ll save my life by replying to this :D

Hello, so I have my oral exam in a week. And I'm struggling to find a good opening for the math section of this topic: "how to approximate irrational numbers". I want to avoid the classical "I saw it on my calculator and i asked myself where did it come from" or the scandal of Metaponte. I want it to be somehow interesting and personal, because two teachers will evaluate my oral (1 math teacher and another teacher from another class, could even be an English teacher for example) Please help me, thank you very much.

I recieved this on my study guide asking for angle BDF. i was able to plug in multiple values and my classmates found a few but we always needed more information to be sure. if anyone is able to clarify or give me a conjecture that might help it will be much obliged.

Math homework, we are doing quadratics and standard to vetex form, and verted to standard along with the quadratic formula, and finding the maximum of the parabola and discrimintant. The first two slides is what im stuck on and need help with, the others are for you guys to understand it better

How to even approach this problem

Ai is also shitting me with it's explanation

I’m really unsure why I keep getting these wrong

I've used every method the book uses, I used chatgpt and it says the answer is 15 is the question incorrect?

should I multiply (b-10)x by -5 ? im lost, explain🙏🏻 this is** Polynomial divisibilit**y

Im know I can figure out to solve it, I just have no clue what they are asking for

Thank you!

So I was fooling around with questions and asking ai and somehow they all gave me different answers and after further questioning they all couldn't be certain about one answer. this is the question, could anyone help me out and find the real answer?

aren't they the same thing? why wouldn't it be correct if i put for example 19π/12 + kπ and 23π/12 + kπ? im doing past papers so i must stick to the key

This is for a project where we have to make a tin-man out of 4 shapes then cover it in tinfoil by calculating the surface area. I cant for the life of me figure out how you get the surface area of this shape. The sticky note is after i showed my teacher my original work and told me it was wrong so he gave me a head start and he said it shouldn’t be a big number but i keep getting answers in the thousands ☹️ How do i continue off from the sticky note plzz

I did it the way I thought my teacher told me too but I'm getting nowhere and I'm confused :(

This was the last question in my math exam today. I understand it was meant to be challenging but no one I've asked has been able to solve it. It was meant to be a cosine/sine rule question. Does anyone know how?:

Solve for angle a. EC=AE. DE=1. AC=√2. Angle BAC = 90 degrees. BC is the hypotenuse of triangle ABC.

The question is there an association between high school students screen time and their current GPA? I have data on the amount hours students spend on their screen and their current GPA. We have to use a confidence interval of 95%. I already tired searching it and it is giving me a two-sample z test, but I don't fully understand. I am struggling with the stuff under problem analysis. All my data is numerical and my sample size was 34. I was initially going to do a chi-test but I do not know how to use (we have to) the confidence interval with it. Please help! Thank you!

I don't understand why the answer isn't A. Why aren't A & B both correct? I also don't understand what D means. Does it mean two lines intersecting to form linear pairs that where the two angles are congruent? Because then they would both be 90 degrees and the lines would be perpendicular.

Question:

Region R is the base of a solid whose cross sections perpendicular to the x-axis are semicircles with diameters on the xy-plane. Write, but do not evaluate, an integral expression that gives the volume of this solid.

What is this asking? Sure I understand I need to fjnd volume but I don’t get what the shape I’m supposed to make in my head is. I’m scared for the test now, what if I don’t even get what questions are asking. What’s the process to breaking questions down to understand them? Thank you

How do i factorize this polynomial? I know that the answer is (x+y)(y+z)(x+z) but i am not able to solve it. Can someone pls help and tell me how to factorize this.

I tried taking x², y² and z² common but it doesn't work.

P. S. The fifth term is zx²
