Not sure if someone already mentioned this, but for the last question you can use special right triangles as a faster alternative to the Pythagorean Theorem. Since both AC and BC must be equal by definition of a circle (both sides are the radius; therefore, they are equal), it means we are dealing with a 45-45-90 triangle. Once we figure out that one side = sqrt 103, we can just multiply by sqrt 2, which gives us sqrt 206.
For the first problem just enter a table into desmos with two points: (27,-72), and (-9,0) which you get from the fact that f(x)=(x+3)*g(x) and the table given. Then just use regression by typing y1~m*x1+b and the answer b=36 will show up in your parameters. Much easier, much faster, and much less risk making a calculation error by hand.
@@adriannarodeo Try using it in desmos exactly as I explained and see for yourself. The ~ symbol, btw, means desmos will perform a statistical regression to evaluate the unknown constants.

For the last problem, notice that, relative positions of points A,B,C do not change if origin of the coordinate system is changed. So, we can shift the origin of the coordinate system to (0, 0). So, C=(0, 0) is the center and A=(1, sqrt(102) ). Since OA =radius = r, we have AB = hypotenuse, which can be easily found using Pythagoras.
First one can be done by doing a regression (give the table to desmos and enter y1 ~ (mx1+b)/(x+3)). It gives you values for m & b which = f(x) & you can test x values. though plugging in -27 gives 2.4, other 2 x values give the exact y value. This method is way faster. And then check manually if you have time. You can thank me later☺
We need videos for the June sat as more as possible, please really your videos are really helpful and important so please john help us to reach the desired high score by posting more and more. thankyou and highly appreciated
for the third question, point A is actually being shifted to the left one instead of to the right, but it doesn't change the answer since it's being squared and you will end up with the same positive value anyways.
Thanks for the video! You actually do know the angles are each 45 degrees because the radii are equal, so the 45-45-90 theorem applies, so you can directly multiply square root (103) by root 2 to get root 206.
dont use algebra for first question use desmos saves you time use the table function to recreate the table they gave you, and write down the questions in desmos but you replace g(x) with y1, the = sign with ~, and all the x's with x1. replace f(x) with the slope intercept formula y=mx+b. desmos will solve and give you m and b and it will only take you like 30 seconds. since it is a linear equation your y-int is the b value which desmos gave you
Bro thank you. Wanted to let u know what a help you've been Ik you probably don't have to do these videos because you have a paid program, but you help so many students out. Just wanted to let you know and that I hope to get above a 1500 on my next SAT! Thanks John will continue to study for the August SAT in 14 days!
For the last question, I just used special rt. triangles. AB=AC since they're radii. So we know it's a 45-45-90 triangle. One we solve AC=√103, just multiply by √2 and we get √206.
Will you be incorporating Desmos in your videos and courses soon? I'd be happy to hop on zoom and teach you all the Desmos functions. I also have videos for most of the tools. I am a full-time teacher and tutor as a side hustle. It would be great toy have your videos as an extra resource for my students.
for question 1 desmos makes it really easy put the points into a table and do a regression to get the equation (y1~(mx1+b)/(x1+3)) and b is the y intercept it will give u the answer
i just used 45 45 90 triangle rule because A and B were radius as C was the centre to find x solve the hypotenuse for a side 1 and side 102^1/2 using pythagoras multiply this by 2^1/2 to get 206^1/2 in ur calculator
I did it by writing the equation and differentiating it took me around half a minute even though I did an unnecessary step of finding the radius which is constant whose differential will be zero. Huh that's it
Shouldn't we use a 45,45,90 triangle instead of a 60, 30,90 since the diagonal in a rectangle would split 90 into 2. thus making a 45 special triangle not a 60,30 one? This is for the circle and rectangle question.
So to confirm are the discord chats on Saturday morning to 10 still going on?My son has logged in twice last saturday and today and there was no one there again ten a m eastern standard time correct?
I took geometry eighth grade (senior now) so I kind of forgot some geometry, so for question 2, is there a proof that shows the diagonal of the rectangle is equal to the diameter, how do we know that they are equal?
Hey brother I worked really hard to attend in the August SAT but my score is delayed and I didn’t cheat or break any exam code. If I did why would I even comment like I didn’t do anything not at all. Please let me know why this happens and will i even get my score. I even closed all the background apps. I am really worried please reply and help me.😢 The score is still not published.
because its a circle? the distances from the centre is called the radius, A and B are points on that circle, so A is a radii length from the centre but so is B, therefore its the same length
Btw for the third problem it is obvious that CB and CA must have the same length since it is a right triangle so just square both then add them then square root it again.

no it isnt. the x coordinate is being increased by 1, shifting it right. If it was substituted into the circle equation then you'd be right.
ye u right
