A function must have exactly one output for every one input. Not all inverses are functions.

@ryanhuynh7509 yes, not all, but this is

(c) is a function, the speaker is either wrong or misspoke. If it's an asymptote as he said, the domain of the function just doesn't include x = 1.

Yeah as @bryangaldrikian9013 said, I said it wrongly and it is actually a function whose domain is x (not equal to) 1.

Bro! I am engaged with my school homework. Send me your doubts. I will clear it. If possible, I will come live during weekends. Which country you are in?

Nepal

Bro! Separate the terms like x = 20/10 + (root720)/10 20/10 will be 2 and the other term can be written as root 720/ root 100 as when you bring the 10 inside the root, it will be root 100 So x = 2 + root (720/100) x = 2 + root 7.2 as when you divide 720 by 100, it will be 7.2. As it is inside the root, it will be root 7.2 Hope this helps

Yeah everything he does makes sense, and is correct, up untill that last part😂.

The 12m line is just an imaginary line i drew. If you look at the image of the question before i wrote anything on it, the 12m line doesn't exist. It is not part of the perimeter of the polygon since it isn't an edge of the polygon.

23 dollars for 1 meter, then for 84 meters (which is 84x the original 1m) the cost will be 84x of the original cost of $23, so i multiplied it to get $1932.

The question asks to prove that mike is correct, so i wrote that. It isnt required to write that but I wrote it for viewers' information

This is for Year 6.

In computer science, you can use 1GB = 1024 MB, but this is math 😁so here we use 1 GB is 1000 MB only. Computer science uses binary system so they use 1024, but math uses denary (decimal) base 10 system of numbers so it is 1000 only.

We need the base angle to be an acute angle, and sine, cosine and tangent are all positive when the angle is acute. The reason we need it to be acute is so that if the trigo function is defined as positive at Quadrant 1, then the answer is the base angle, if it’s Q2 (sine only) the answer is 180 - base angle, if it is quadrant 3 (tan only) then it is 180 + base angle, and if it is quadrant 4 (cosine only) then it is 360- base angle. Sine is positive in q1&2, cos is positive in q1&4, tan is positive in q1&3

yespls

Yes, extended paper

Oh wow.. good luck, do your best!!

Thanks

In this question, you have to relate your answer to the height of the water, so writing gradient has gotten steeper alone is not enough here

10^-1 is the same as 0.1 anyway, so yeah, it's correct as well

That answer is true, but the question has asked for how the GRAPH shows evidence for the question. Yeah, the % population does increase, but why? What does the graph show that proves this? That's what the answer needs

@@MathandSciencewithSV Thanks bro

It’s April 2023, bro!
