I tried inputting a number other than 100, I tried 226 in periodic table and custom value of 50. I still got the correct answer. I finally understand why "K" proportionality is important. It's used to model equation and to always arrive at the correct answer no matter the value is given. Amazing! For this case, of course if a particular value is given, well a different answer is obtained. Anyways this works like magic lol
Thankyouu sir kasi sobrang naexplain nyo po ng maayos bawat examples. Sobrang nakatulong po sakin ito as an "ECE Student" 🤗 And bawat exam ko po ay nasagutan po lahat dahil sa tulong po ng mga videos nyo🥰
Can you help me in this problem about solving involving exponential growth/decay? Thank you!!! Problem: Rhyz and Zhayn lives in an island-town with population of 2000 people. They came back from vacation to the island but they catch the highly-contagious COVID-19. A week after their return to their town, they infected 6 more people. a. How many will be affected after another week (assuming no health protocols have been practiced.)? Their public health center decides to isolate their town once 30% or more of their people are infected. b. After how many weeks will the public health center isolate the town?
sir bakit po sa #1 problem nag nung nag subtract po kayo ng 0.6% ay ganito x=20-20(0.006), pero sa problem #2 bakit kaiba po ganit po x=100-1.1%? Thank you po
Thank you for this. Do you have an additional video about this topic po na mahihirap yung problems? Kelangan po kasi namin for our culminating activity! 😅😅
Sir how po kung ganito yung question, the half-life carbon 14 is known to be 5270 years. doc frankenstein has 300 grams of carbon 14 in his experimental laboratory. if untouched how many of the 300 grams will remain after 1200 years
Kuya request po pano kunin ito,? In 1990, a small town had a population of 15,000 people, since 1990, the town has increased 3% per year. What was the population in 2005? Hihi salamat po GODBLESS!!
@@abatandchillmy bad sir😅, it's actually the same procedure, just with a different way of showing solution. I was just confused with it a while ago from the ln. What I did is subtracting the 0.6% from 100% first and multiply it to 20 Y = Yo e^kt 100%-0.6% = 99.4% = 0.994 Y(10) = 20 (0.994) Y(10) = 19.88 subtitute to Y 19.88 = 20 (e^10k) 0.994 = e^10k ln 0.994 = 10k k = ln 0.994/10 1. y(t) = 20e^(ln 0.994/10)t t = 10 10 = 20 e^(ln 0.994/10)t 1/2 = e^(ln 0.994/10)t ln 0.5 = (ln 0.994/10)t t = ln 0.5/ln0.994/10 2. t = 1151.78 years y(900) = 20e^(ln0.994/10)(900) 3. y(900) = 11.63g

a. How many will be affected after another week (assuming no health protocols have been practiced.)? Their public health center decides to isolate their town once 30% or more of their people are infected.
b. After how many weeks will the public health center isolate the town?
Very good, you really know how to teach
Thank you to God be the glory
for the question #1 engr, why is it 11.63grams is the answer when the question asked is the "amount remaining in 900yrs"?
sir bakit po sa #1 problem nag nung nag subtract po kayo ng 0.6% ay ganito x=20-20(0.006), pero sa problem #2 bakit kaiba po ganit po x=100-1.1%? Thank you po
Sir. sana po meron pang part 2 ito para may mapraktisan pa kaming problem hehehe also pra more learnings😊😊😊
THANKYOU PO SIR MORE POWER PO & GODBLESS!! ✨
Thanks for your good explanation 👍 👏
You are welcome
God bless you Sir... This is explicit. Kudos Sire
thank you so much sir for this video, god bless po
thank you po Engr.!
Thank you very very much...
god bless po.
Grabe dami ko natutunan thank you sir hehehe
I think dapat e^-kt po Ang ginamit since the problem is an radioactive decay?
Thanks sir love from India please reply😅🙏
Namaste!
@@abatandchill 🙏🙏
can we use the formula X=Ce^kt? when finding the half life without any given x just percentage of decay and time.
thank you sobra engineer!
Sir also make a video on limited growth with harvesting as soon as possible 🙏🙏🙏
Sir it is also correct if dx/dt= -kx? there's a negative sign in k. Thank you.
Sir thank you po . God bless
Thank you for this. Do you have an additional video about this topic po na mahihirap yung problems? Kelangan po kasi namin for our culminating activity! 😅😅
For now ito palang. But I will consider your suggestion for even harder problems
I have a question po regarding example number 1 (C), I tried calculating it in my sci cal but the result is not 11.63g
same:
baka di mo nilagay yung 20e
thanks for the lesson sir it is very clear
Thank you sir 🙏🙏🙏,God bless you.🙏
I have a question in the first problem, shouldn't the k be negative since it is a decay problem?
No.
Saan po nangaling sir ang 97.81 g sa letter C problem number 2. Yong kinuha po ang %
sir anong app po gamit nyo sa pagrerecord at pagsosolve nyan?
Superb bro
Thanks bro
Thank you Engr.
Sir how po kung ganito yung question, the half-life carbon 14 is known to be 5270 years. doc frankenstein has 300 grams of carbon 14 in his experimental laboratory. if untouched how many of the 300 grams will remain after 1200 years
Thank you so much sir. God Bless🙏
Thank you so much, sir. God bless u!
Same to you!
hi, sir! ask ko lang po if okay ishift solve yung (k)? para mas konti yung solution. thank you po
SO HELPFUL. THANK YOU SO MUCH
What book/reference are you using Engr?
Elementary DE by Rainville
Thank you engineer ❤
bakit same k ang ginamit sa a and ba na 20 percent naman ang nag decomposed sa b, hindi 1.1 percent. Please sana may mag sagot
Hello po, bakit po sa ka Isiah James Maling yung k nya ay negative po
Thank you for this video sir😊
You're Welcome
Thank you po. 😁
pano po nakuha yung 11.63 grams na sagot sa unang problem?
Sir please make a video on population model regarding birth and death rate
I will try my best on this. Thanks
@@abatandchill thank you so much sir🙏🙏
Sa example number 1 sir problem C saan napunta yong 20e?
Is this law of exponential change po?
I got exams later, thanks!
Sir salamat po talaga SA mga video nyo sir Sana may Dynamic Inclined ODE Naman sir❤️❤️❤️
Hello po sir. ask ko lang po bakit po don sa " In x" wala po absolute value sign
Hi po engr. Meron ka po video calc. tech. Para dito sir?
sir lahat po ba ng about sa decay ganyan po ung equation?
applicable po ba dito yung pag forecast ng mango exporting in PH after 5-10 years with application of D.E. ? thanks po hehe
Maybe
thank you sir ❤
Kuya dapat nagbibigay karin nagsample para may maisolve din namin. And answer key na rin sa last. Hihihi. 😂
Ok I'll try to consider this one. Though there are lots of sample problems available on the internet or books. :)
Kuya request po pano kunin ito,? In 1990, a small town had a population of 15,000 people, since 1990, the town has increased 3% per year. What was the population in 2005? Hihi salamat po GODBLESS!!
Sir pwede ka mag vid more examples sa exponential growth and decay yong may half life tapos complicated ??
THANK YOU SIR
Thank you so much bro
Thank you so much engr.
You're very much welcome!
@@abatandchill Is it possible for you to make a video for engineering surveys?
Pahinge ng talino mo engr. Midterm na namin bukas😭
salamat sir
thank you sir...
Most welcome
Katulad lang po ba to ng simple chemical conversion?
Yes
Hello po sa sample problem no. 2 nag assume po ako na ung X is 25 nakuha ko po ung answer same sa A at B. Yung C lng po naiiba HAHHA help po
okay lang po ba kung walang negative sign ung kt sa general solution kapag decay?
i mean ung k po
thanks again sirrrrrr❣️💞💕
Sir correction lang po sa part 5:20, hindi po ba 6% = .06 dapat?
0.6% po yung nasa problem which is equal to 0.006
life saver gid yaaaa aaaaaaa😭
THANKKK YOU SIRR
Sir pwede po malaman reference book mo po?
Btw thank you po dito sir! Napakalaking tulong po 'to sakin :))
DE by Rainville
@@abatandchill anong edition po?
Thank you sir!
You're welcome
tysm engr.!!
You're welcome!
Book reference po?
Elementary Differential Equations by Love and Rainville :)
@@abatandchill thankyouuu po💗
Thanks sir.
Sir, 20% po ng 100 ay 20 po
Mas ok pag shift solve nalang ginamit para mas mabilis
Yes pwede naman
Thank You!
You're welcome!
Thank youuuuuu😍
Thank u engr
Bhaiya hindi m explain kr dijiye
CESARIOOOO
Engr. 11.5177 nakuha ko
Isang taon na, same tayo bat ganito. Na solve muna?
sana kung magturo ka e explain mo talaga kung paano yan nakuha
NGANONG 11.63 😭
Your way is sadly more difficult to follow😢
Then show me an easy way 😊
@@abatandchillmy bad sir😅, it's actually the same procedure, just with a different way of showing solution. I was just confused with it a while ago from the ln. What I did is subtracting the 0.6% from 100% first and multiply it to 20
Y = Yo e^kt
100%-0.6% = 99.4% = 0.994
Y(10) = 20 (0.994)
Y(10) = 19.88
subtitute to Y
19.88 = 20 (e^10k)
0.994 = e^10k
ln 0.994 = 10k
k = ln 0.994/10
1.
y(t) = 20e^(ln 0.994/10)t
t = 10
10 = 20 e^(ln 0.994/10)t
1/2 = e^(ln 0.994/10)t
ln 0.5 = (ln 0.994/10)t
t = ln 0.5/ln0.994/10
2.
t = 1151.78 years
y(900) = 20e^(ln0.994/10)(900)
3.
y(900) = 11.63g
Then use what's easier for you as long as it will arrive at the same answer.
Sir please tell in english
It's already in English :)
@@abatandchill no in hindi
It is in hindi
What r u talking about man, he already explained it in english..
