Given that MN = 2 and that the curve represents the function -2logx in the base 1/3, what's the value of AB + BC + CD + DA?

i dont know, this is why im a NEET.

Too tired now to do this but use these forumlas and simply put the numbers from the diagramm and ypu will calculate the area , the gray part

But the problem is not asking for the area

the legth ?

the legth ?

The sum of the lengths of AB, CD, DA and BC

okay CDA is easy because it is a 90° triangle.
ABC use this formular :

I wont calculate an answer because this kind of sftuff I last did in highschool. Forgot how to do it properly and too hangover to look it up.

Am I at least correct with the formulars?

I can solve this problem but this graph is bullshit. For -ve coeffecients of log x graph would be upside down

The coeffecient is positive though

2a-3
2a = 3
a = 3/2 = 1,5

ABa/2 is also a 90° triangle

I don't know much about integrals, but since they are used to calculate the area, I don't think they would help in this problem

2a-3
2a = 3
a = 3/2 = 1,5

ABa/2 is also a 90° triangle

Then a/2 would be <1, which would mean it's behind A

 

[Caesercel]

The coeffecient is positive though

Literally says -2

 

[trying to ascend]

Literally says -2

The base is 3 to the power of -1, therefore the log coefficient is positive

this integral is for length of arcs not area of surface.

But we will see when you post the answer. Also postthe steps of reaching the answer

Oh. Let me work it out then

 

[Caesercel]

2*underoot2 +2*underoot10 + 12

 

[trying to ascend]

2*underoot2 +2*underoot10 + 12

Correct

You’ll use these questions when you’re flying the jets

Fucking trash

I'm not going to that institution and you need to have a vast knowledge in physics and math to succeed there

Yeah I know, its for the best genetically superior people ,fuck them ,and I passed from these faggot courses in stem with the lowest marks ,still passed and I hate it so much
