SP6: unit K concept 10- repeatibg decimal to a rational number

Hello I'm Ana from period 4. Things that we must careful of are to put tge correct number of zeroes infront of the grouped number. We must also remember that it is a repeating decimal which means those numbers do not stop there they go on forever. We must also remmeber the 2 that was ubfrobt of the decimal because that is still part of our repeating decimal .when we bribg ut back down we set if to equal the denominator of 99 so we can easily combine it to 31/99 which is what we got before we brought the 2 back. Once we have added 198 /99 and 31/99we get 229/99. You can chrck this on your graphibg calculator by plugging it in and you should get the original decimal that we had.

Thank you. I hoped this helped :D

SP5 unit J concept 6-solving systems of equations that have repeating denominator s.

Hello this is Ana from Period 4. Some thibgs that ypu must be careful of when solving this problem is making sure that our distribution is correct. Also. When combining like terms to make sure that the addition and subtraction are correct. we muat be very caregul when it comes to the signs. When pluggibg it into the graphing calculator to use RREF and after plug in the A B and C into the decomposed part of the problem. When checking your answer we mulitiply the common denomitators to the bottom if everythibg cancels out to add to the original numerator.
I hoped this helped. Thank you.

SP4: Unit J Concept 5- Partial Fraction Decomposition with Distinct factors

Hello this is Ana from Period 4. Somethings that you should be careful with Decomposition is when foiling to be very careful with the positive and negative signs. You must be very careful with the simple mistakes because they can change your entire answer. Also don't forget to distribute the A, B, and C to the corresponding parts. When combining like terms be sure to set it equal to the like term that is in the original equation. To make sure that everything is correct just plug it into your graphing calculator by pressing 2nd matrx, edit set to a 3x4 scale, put in all your values, 2nd quit, 2nd matrx, math, RREF, 2nd matrx again, enter, and close parenthesis. I hope that this helped.

Thank you.

SV#5 Unit J Concepts 3-4: Solving Matrices

   

This is Ana from Period 4                                
This Is  Doctor Problem #5. The things that we must be aware at and pay close attention to is that when I am looking for the zero i always use the row that is above it to turn it into a zero. Also, make sure that by the end we create a triangle of zeroes at the bottom and a down step of ones. Also when checking for your answer in the graphing calculator you use matrx, edit, and make sure it is a 3x4 scale and write the correct numbers in. Then we press second quit and matrx again, math and search for RREF. then select A and close the parenthesis. When checking for your answer the values of x, y, z will be listed vertically.

I hope this video helped. Thank You for watching.
