Hello, I am Mr. R. If I made any mistakes then leave a comment and I’ll respond.

[aarush]

We're making to an A in the class with this one 🔥🔥🔥

For FRQ 4, part B i) the directions at the top do say to simplify. 22:08

[ufohoh]

at 22:07 i became stupid and forgot how exponents worked and assumed you couldn't simplify log(16x^7/x^9) without having negative exponents 💀
everything else i think i got right, light work

[tbocelot]

for frq 3, isn’t point f at 1.5? you can’t have negative time so the second time the wheel would hit the ground would be 2.5 seconds at J.

I put pi/8 and not the integer stuff because I thought arccos had a domain of (0, Pi) I’m cooked

Hi Mr. R

For the FRQ with the sin graph, I wrote the a (amplitude) as positive 9 and added a shift by -1 (1 unit right). Do you think they would accept that as an answer as the graph is still the same graph it is just shifted

1. Do I lose points for FRQ 2C if I said that model G doesn't model real world phenomena because, as a logarithmic function, it always increases as x increases without bound, even at a decreasing rate, even though video game sales are likely to decrease after a certain point?

2. I got the same answers for FRQ 3, but how can time (t) be negative?

3. Do you lose all points for a particular part of a question (say Part B) if you get 1 subsection of it wrong (e.g. Part B ii.)?

4. Will I lose points if I left my final answer as log10 (((8x^5)(2x^2))/(x^9))^10?

5. How cooked am I?

[warmsweettea]

why is the answer pi/8 + pi/2 *k instead of just pi/8? Isn't the domain of arccos [-1, 1]?

[Bio_Man]

I got a different frq know when that’s gonna come out?

[prasna]

for question 3, my c value was -1, would that work?

[Mandq.]

any idea what will happen bro? all exams got leaked
