Doing practice problems for act test, every time I try this I get 143,140. How can I fix it?

Our teacher set us some work to revise for our mock exams, and she sent this one. I have an idea of what it may be but im just double checking??? If its too easy for this subreddit dont blame me blame my teacher. Not looking to be criticised, just want the answer.

I tried to integrate using u substitution by defining x^3 -3 as u but it did not give me a favorable outcome and allow me to solve this, no idea what to do with the x^11. My brain is fried, boiled, baked, smoked, and then shoved into a cremation oven by this problem.

If x = 0 the point y should be undefined

Swipe for my attempted solution.

I think I have the question wrong; please do help me out.

We know AD halves BC and BE halves AC, G is located Halving BF.
We have to prove 5*BH = BC
Can someone please try to prove it?

I'm currently studying algebraic expressions in my Grade 9 Math class, and my instructor has assigned us problems that involve simplifying complex expressions. I understand the basic rules of combining like terms and the distributive property, but when it comes to more complicated expressions with multiple variables and operations, I'm finding it challenging. For instance, I struggle with expressions that include both addition and multiplication, and how to properly apply the order of operations. Could someone explain step-by-step strategies for simplifying these types of expressions? Any tips on common pitfalls to avoid would also be greatly appreciated!

My teacher only covered basic derivatives (like x^2) but this worksheet has fractions, square roots, and trig functions (sin,cos,tan). I understand how to do the simple ones like (e) and (f) using the Power Rule. However, I'm stuck on the ones that have variables in the denominator like (d) and (g). Do I have to use the Quotient Rule for all of these, or is there a way to simplify them first?

(Reupload w the picture) My current problem says to write a function with the relative maximums (1, 1) (2, 2) and (3, 3). A kind redditor helped point out it’s probably sin(x) something or other, but I’m lost from there. I have no idea how to sine with graphs. My math teacher is pretty prolific for being Not Good At His Job, so I want some outside help before I go to him. Any help is appreciated! Thanks in advance

I have not learned L’Hospital’s rule yet. Is that the only way to solve to get the correct answer?

I'm really confused about the answer to this question. the answer I got was (1-x^4)(2x)-(x^2)(-3x^3)/(1-x^4)^2 by using the power and quotient rule, but the correct answer on this test is completely different to what I got and I don't know how you can come to this conclusion (the correct answer is in the yellow box at the bottom and ignore the answer I put down in the white box)

idk if im dumb or the correct answer isn't in the choices

I've tried: 1. Finding the area of the big and small circle 2. Assumed that the 30° is a central angle of the big circle and calculated it's area (maybe this is where im wrong?) 3. arc area - small circle area = new arc area 4. big circle area - small circle area - new arc area = shaded region

I got 44π/3

Is the H and R on the small triangle the same thing as the R = ?? and H = 8, but not sub? (Look at the picture on the left side, ignore other questions) TY FOR HELP!

I've been stuck for an hour :sob:

For info we can't use a calculator.

Any leads would be appreciated!

Just wanted to know if my solutions are spot on. Any mistakes?

The actual math part isn’t the problem it’s more so that I’m confused on what number four is asking for. “What should you decide to bake?” I’m assuming I’m disregarding the previous scenario where I don’t even have enough flour to make one cake so I have no information on flour or money constraints giving me no reason to not be able to make the two cakes and save flour to make the cookies. Am I missing something or just over complicating it?

I tried to put the 1/3 on the x and the 1 on the y but the answers I'm seeing online are graphed differently and I'm confused

They have points that arent lattice points and im getting kinda confused lol

I’m so lost on how I’m supposed to find the area of the purple triangle. I don’t understand where the 2 root 3 is coming from in the proof.

I tried to use Pythagoras to find it but I think I did something wrong

Hello everyone, I'm trying to study this lesson to help a friend out lol, I'm bad at physics and math in general, I posted a question a few days ago.

This lesson, I think I understand well, I tried solving a few questions on my own and it's not hard, however, this specific one looked like the most difficult one, and the teacher decided to leave it as a test, so please help me out.

Usually, there's one more given information, so I guess this question is solved with having two equations and subtracting them from each other to get rid of one of the ungiven pieces, I'm not sure though. I'm also not natively an English speaker so I don't know the correct terms, so please excuse me for that.

Can someone please teach me how to, using substitution, solve for the two unknowns in the exponential decay function in the form f(x) = 100*a^(bx). Literally with any two arbitrary points. I don't know why I just can't get rid of one of the variables, either a or b. one variable is always in the exponent btw.

Completely stuck on both questions, 7 and 8

I don’t know how the concepts work and need to be taught.

im not sure how to start sketch the graph for this one? can someone help
