Well geno says its 28 but then Guest says it 13 I'm not really sure
A = (9 * 5) + (6 * 4.5)
Oh my gosh!! That makes so much more since now.
Sorry, can you please put in LaTeX? Also, I don't quite understand how you got the 'quite easily' from the telescopic sum.
Yep 11.
You need to tell them how you got the answer and what it is :P
It's hard to tell is it a 6 or a 5?
Cause trying to write it out doesn't work just like the dollar sign :/
but I would be happy to help!

Which one did you try?
=^._.^=
Oh thank you!
There are only two lines for me, Do you happen to have a photo of the question?
Wait how big are the posters?
Oh yeah, they could just go here Dude I solved it for no reason oof
Sure....here is a graph:
is it safe to assume the prime number's 13?
And or explain it better :D!
Wait is that really the answer I've been staring at this thing for a while now :')
10x^2 -3x-1 -1 is the y -intercept (it looks like)
and it is a bowl shaped (rathe than dome shaped) due to the POSITIVE x^2 coefficient ( +10)
The poor dollar sign
I got x=10, so the perimeter of the rhombus is 4x= 40

Well, my answer was 9/61 9 ways out of the 61 ways of using 2. 21+16+24= 61. the hesitation comes from wondering why so much other irrelevant info? Like so much 0-0
-wolfchuuuuuu
I actually think your right! Thats a tall brain UwU
Oh that's why I got it wrong I forgot the sign for -120 I said 120 (ー_ー)
See that's how dumb I am today!
Another way to get the answer:
To find the maximum, find the first derivative and set it equal to zero.
Problem: P = 120·i - 5·i2
First derivative: P' = 120 - 10i
Setting the first derivative to zero: 120 - 10·i = 0
-10·i = -120
i = 12 amps
Since the vertex is (-4, -4), the equation is: y = -5(x + 4)2 - 4
