So x^2 + (-2x)^2 = x^2 + 4x^2 = 5x^2

Does that make sense?

You're welcome and you got this! Good luck!

Really sorry! I had it recorded but didn't attach it but 19 is an inverse question so for your equation it is originally y= x^3-3 but as an inverse it is written as x=y^3-3. Add 3 on both sides to get x+3=y^3 then cube root. After that you have cube root of x+3 and then examine what times -3 will get you 3 and that is -1 so answer choice 2.

Good luck doing it in August ig

Good luck!

Nice to see you here! Good luck on your exam tomorrow! Remember to keep on singing!

So in quadrant 2 of your coordinate grid, x is negative and y values are positive that is why we eliminated the first answer choice because (1,-2) isn't in the second quadrant. Does that clarify it?

Then you substitute -2x for y in x^2+y^2 to get your possible values of x which are either -1 or +1 and you eliminate answer choice 2. Then to find the answer between 3 and 4 you substitute -1 into either equation to get your answer for y. Does that help?

So when you graph your equation you will see when it hits it peak so to find the exact value you would do 2nd trace, scroll down to maximum and then choose your left bound enter , your right bound enter, and then put your cursor on where you think the maximum is and then once you click enter it will give you your x and y value at the maximum. Does that clarify it?

A lot of the half-life questions will show up with radioactive substances and they would be in the form of exponential decay as half life is the time it takes for something to reach half of its amount. So "e" is the inverse of ln so whenever you have ln and you need to inverse it use "e". "e" will appear in your compounded continuously formula and ln is natural log. Let me know if this make sense! Good luck

@@LearningwithHaneen Ok thanks

No problem! Good luck!

The recursive formulas are not on the reference table just the regular sequence formulas for arithmetic and geometric

No problem!

Remember your recursive formulas, know your unit circles, know vertex form for a parabola, formulas for directrix, focus, compounded formulas and compounded continuously, remember your I circle, equations for sine and cosine, know z-score formula.

tysm!! good luck on your final exams!

@@monkeybrain2017 Thank you and good luck as well! Just make sure to familiarize yourself with all formulas and you got this!

You are not! You have taken this class and this is something you should be proud of! You got this and believe in yourself!

@@LearningwithHaneen nah we cooked

​@@AthletezBagDawg 😭

Nah I'd Win

Same 😅

Believe in urself!

Thank you so much for your sweet comment! Good luck on your exam tomorrow! You got this!

@@LearningwithHaneen thank you!! 💗

Why if I may ask? To clarify you plug in both equations to the calculator and you find the x value at which they intersect, but you can't choose -1.9 because it doesn't fit the domain of t > 0 Hope this helps and thank you!

you can also sub in each answer for x for both equations and see which answer makes both equations equal

I will try my hardest to do some short videos but I do have a Spanish regents tomorrow but I will try.

Thank you for your support!

Thank youuuuu!!!

@@LaurenM-l2l I am posting a few questions on fractional exponents.

So (-2)^2 equals 4 and then (x)^2 equals x^2 together they equal 4x^2. Does that make sense?

@LearningwithHaneen Yes that makes much more sense thank you so much 😊

Thank you!

You got this!

Okay, I will provide one as soon as possible!

Just posted it!

@@LearningwithHaneen thank you so much!

You got this believe! If you need any specific topic review let me know!

@@LearningwithHaneenCould you make a review on fractional exponets?

@@capid3866 just posted it!

compounded monthly is multiply the time by 12, compounded continuously is multiply the principle by e, and annually is multiply the time by 1

Compounded annually and monthly fall under the same category but when you multiply annually your n will be 1 whereas when you multiply monthly your n is 12 in the equation A= p (1+ r/n)^nt (will be identified in the question). Compounded continuously is an account continuously earning interest and you would use the equation A=Pe^rt.

@@klaus5872 thank you!

Thank you so much for your comment! So on your calculator there isn't necessarily a way to convert from decimal to square root but when you do - square root of 2 and then put it to the sixth power you will get 8 and then just bring down the square root of 6. Also, after getting your answer as a decimal, you could plug into your calculator all of your options and see which one matches (I start with 3 because it's right in the middle). Let me know if that helps!

@@LearningwithHaneen Hi I don't get this part, I sat for an hour trying to figure out how to calculate the square root equation. So did you do it with a calculator?

@@musaffakahn5526 so first you multiply both the numerator and denominator by √6. Then you have -2√3 times √6 which simplifies to -2√18 (numerator) When you simplify √18 you get √9 times √2 and then simplify √9 to get 3. So now you have -2*3 = -6 and you put the remaining √2 (numerator). For your denominator √6 * √6 = √36 = 6. Altogether you have -6√2 / 6 and you will get -√2 (-6/6=-1 and you bring down √2) Let me know if that makes sense.

@@LearningwithHaneen It does thank you so so much

@@LearningwithHaneen Thank you for your help!

Don't underestimate your abilities!

Synthetic would work as well, it's just personal preference and for me, long division is just easier. You can use whatever strategy is best for you 😉 Also thank you for your comment, you got this!

Or u could plus an x into the equations. It would be a lil longer though

You totally can! But remember you are under a time limit so if you can start solving using long division you will reach your answer faster, especially since the answer choices are different.

I apologize but I don't have access to a ti-nspire cx2 calculator. If I had access I would show you how to use it. Sorry!

Don't underestimate your abilities!

Thank you so much for your comment! I could try to post small shorts tomorrow throughout the day solving some questions. If you have any specific topics let me know l and I will try. (The lateness in time for posting these is on my end) Thank you

nah you'll be fine. Just go over past regents, and turn to the calculator for MC

Same, I only had less than 6 months to prepare for the regents and all the practice regents I have been doing, I’m confused on almost every question 😢

@@etonymous1632 ya thats what ive been doimg im just nervous bc i thought i did good on geometry last year and studied but i didnt do as good as i thought 😭..

@@mari-bazzi nah, unlike geometry, this test is like 80% calculator, I’m sure of it
