1:43:44 not quite sure how the zero makes the right hand side of the equation dissapear, isn't be^(0/5) just b to the power of zero, which is equal to "1", rendering the right side to be 200*1 so equal to 200? I would believe that the equation should work for all of its table of values.
If you did that, then b would have to equal 1, which it does not. We needed to use different values in the table to determine the correct value of b, which is 0.8
A linear function changes at a constant rate (as represented by the slope). Exponential functions change at exponential rates (thanks to the exponent).
I would like to point out that for number 35, you can just graph g(x) and find the solutions that way. You don't have to look for extraneous solutions and, most importantly, it saves a lot of time because the SAT draws to scale unless explicitly stated.
Thank you very much for clear explanations .However , I have got one question .Why at the final problem (38) you used 5 minute from the colon ,why not other minutes ?
Thanks so much for watching our videos. Glad they’re helping. You really could plug in any of the points and get the same answer after it’s rounded to the nearest 10th. The only combination that won’t work as the one that has a zero because it will cancel everything out.
Hey love your channel and how you explain your process to getting your answer. I really appreciate it truly. Is there any tip for the timing for math. It's like my anxiety get the best of me and my brain, even though i know the method, just goes blank. Any times for that?
Thanks so much for the encouragement. Our tip for timing is to do everything you’re good at first. Be very willing to skip any question that’s at least a little bit of a headache, the first time you go through the questions. Most people miss questions that they can easily get because they spend so much of their time and energy on the questions that they are not good at. Also, timing comes from familiarity so keep trying questions and reviewing the videos to see the right way to do them. As you keep getting more comfortable with the subject matter, you’ll also get faster. You can do it!
It is all relative: if the community only contains 100 families, 20 families is not small. However, here, the more important error is the bias by asking families in a playground.
Watch the explanation again. If t is number of years and q is quarter years (of which there are 4 in a year), then we need an exponent that is equal to 1 year after 4 quarters, which is what A gives us. If you picked B, then after 4 quarters, our exponent would actually be 4x4 which is 16.
we really have to appreciate this guy going out of his way to help students like us do good on our exams. thank you so much!
Thanks!
Wow, you made things that seemed so hard at first, really simple. Thank you so much!
Thanks and that’s our specialty!
Underrated channel. Keep up the good work!
Thanks!!!!!!!
Thank you so much! Please keep making videos like this, you are a lifesaver!!
Thanks!
I wish i had been using these instead of scalar learning. These are far better
Of course they are! Stay tuned for more great videos like this.

This is actually so helpful!!! Thanks!!!
That’s what we love hearing and thank you!
your actually a genius for the strategy in question 24
Now you can be a genius and use it too!
how do you know if it is linear or not? don't exponential functions also have a constant rate(i.e. growth factor)?
A linear function changes at a constant rate (as represented by the slope). Exponential functions change at exponential rates (thanks to the exponent).
Ohh thank you! Do you have any tips on how to deal with word problems such as this one and how to avoid careless mistakes on those?
@@yujinabasnet8022 just eliminate whichever one it’s not asking and it will most likely leave u with 2 choices
hi sir i love the way you explain there questions i am so grateful you made these video
We love to hear that, thanks!

There is often more than one correct way of solving a question; we are simply showing one of them here. Yours is good too!
Thank you!!! This is awesome!
Our pleasure, Rani!
thank you so much you explained every answer in detail
That’s our goal, glad it was clear!
For number 38 what does the within "10 micrograms per millimeter" mean.
It is the range within which P approximates the values in the table (it is a measure of concentration).
You are the bestest🙏🏼
Thanks!
Thank you so much!!!

@@Gradefultestprep Thank you so much🙏
Thank you!
Our pleasure- thanks for watching!
Bro you are the best, i bet you👍👍👍👍💣
Thanks!
Thanks so much this was super help ful. I just dont get why i see such a great difference in my math score, like i can get a 620 then a 670
Our pleasure and keep practicing! The more practice questions you see, the more your score will improve and hopefully top out at an even higher score.
Can please do a video on writing and language tips pleaseee
We already have some for other Practice Tests. You can check those out in the meantime for some general rules and tips.
in my opinion, 26 can also be b. a sample size of 20 is considered small
It is all relative: if the community only contains 100 families, 20 families is not small. However, here, the more important error is the bias by asking families in a playground.
Hi!
Hi Joshua
That's my fourth video after taking the four tests today :D
Great job Omar!

Hi Gary!
I don’t get why no. 23 isn’t B
Watch the explanation again. If t is number of years and q is quarter years (of which there are 4 in a year), then we need an exponent that is equal to 1 year after 4 quarters, which is what A gives us. If you picked B, then after 4 quarters, our exponent would actually be 4x4 which is 16.
Gradeful ahhh okay thank you!
