I have a question about the Practical problem... why is the value 150% and not 50% ?
@mrhallatwork
@mrhallatwork 2 месяца назад
It is increasing by 50%, so then you will have 150%. e.g. yesterday I had 100%, then it increase by 50%, so now I have 150%, or 1.5

mistake in question 5, in the 3rd step coefficient of "h" at very top of fraction should be -1. And so final answer after cancelling out h and diving through should -1/x^2 not +ve

I got confused, you waffle way too much. I do not care about examples, how do I just get the simulation I want in the sheet to run it. I should not have to put in "game inputs" to set one up

Sorry. I don't have it in a shareable format anymore. Anyway, my aim was that my students would make their own and learn through the experience. It really won't take long to make your own. Plus you can customize it to your own questions and any pictures you already have. Good luck.

@mrhallatwork
@mrhallatwork Год назад
Find the x value of the maximim/minimum by x = -b/2a (or half way between the 2 roits) and then put that value back into the original y=,,, or f(x) =,,,,, equation

Hello, I used your method a week ago, it was wonderful. But, I do it again now following you video. When I press "enter" button, it say "Singular Matrix". I keep trying, it keeps giving me this message.
@mrhallatwork
@mrhallatwork Год назад
Singular matrix means it has no inverse. So you will have to think about what that means for the specific question your working on.

Thank you! I was about to start a harder version based on the earlier part of the video (like doing a "randbetween(1,52)" and identifying what card each number represents)... ugh, glad I watched the end! BTW, you can hide full rows/columns by right-clicking on their headers (like where you'd select for filtering or resizing), but you'd have to move that other stuff at the top over to the right so it doesn't get hidden.

@mrhallatwork

Graph y = 2^x (increasing exponential curve) and then graph y = 32 (horizontal line). They should intersect at x = 5

I have three kids doing Junior High and High School math remotely. I watch a lot of math videos with varying degrees of complexity. This one seems a trifle challenging, particularly in the way he works so quickly. I'll file this video for future use when my Algebra skills are a bit stronger. Having said that, there's some valuable info in this video.
