Still updating it, about half way complete - I'll set this to public when it's all done
It's only 10 problems but with all the parts there's about 50 questions altogether~
The video description has a list of all the ones done so far
As I do new ones, I update that~
The main thing revised from the previous version is number 48
Every vertical line is parallel to the y-axis ~ So the correct answer is Choice (D) x = 2 for the downward-facing parabola's axis of symmetry
Also, I just highlighted something else on the probability question with the chart~
Corrections/Typos on screen:
Number 57 at 15:37 ish
That first blue line should say
"cos 30 degrees = adjacent / hypotenuse = AC / AB = AC / 40"
Im hereeeee😂❤
hey can you weigh in on this question
czcams.com/video/gyBC5Hj8U7o/video.html
did you think it is B or choice D?
@@csec-maths-chem-paper1s at first without the contradiction part it would have been B as A and C can safely be eliminated, but as it further stated that cat owners can have a dog the only one that matching up to make sense is D
@@csec-maths-chem-paper1s and for num 12 on this paper they took out the contradicting part! So I think they realize the mistake so don't hurt your head too much on that one
For number 22, why wouldn't the denominator be squared? Why is it 'B' and not 'C'?
factor out the 1/x and call that X
so we now have X times (one half + one third)
there's no way x could be squared from this, even after we added the fractions
when adding fractions
we establish a common denominator
once we get that, then we just add numerator terms and put that over the common denominator
so (1/x)(1/2 + 1/3)
the common denominator is 6
which means you multiply the half part by 3 over 3
and you multiply the third part by 2 over 2
and so now we have (1/x)(3/6 + 2/6) = (1/x)(5/6)
and when we multiply fractions
we just multiply numerators to get 1 times 5, which is 5
and multiply denominators to get x times 6, which is 6x
so altogether we have 5 over 6x, final answer~
Do they repeat questions for maths multiple choice ???
yes, big time
just look at the questions from year to year
you'll see tons of repeating questions~
youtube search "predicted 2024 csec maths" multiple choice question ~ the reason they can even make those predictions is because of the highly repeating ones btw, worth checking those vids out~
Last time I check I taught question 60 was D or a switch dem switch it up?
dem switch it up mn
hey, check the comment with @JulieGeorge below
she also thought it was choice D, but I explain why it isn't there
in short, angle x isn't the repeated base angle
so you have something like x + y + y = 180
where angle R and angle Q correspond to the y measures
the base angles are opposite the congruent sides of the triangle
GL today!
I thought 15:39 was “c” because of the interior angle “30 degrees”
Number 57, question at 15:27
AB = hypotenuse = 40m
AC = adjacent side to angle A
BC = opposite side to angle A
cos A = adjacent / hypotenuse = AC / 40m
AC = 40 m times cos 30 degrees
but notice that is not a choice
you could use the cofunctions things mentioned in the video
or proceed like this:
so lets try angle B
AB = hypotenuse = 40m
AC = side opposite to angle B
BC = side adjacent to angle B
sine B = opposite / hypotenuse = AC / AB = AC / 40m
AC = 40 m sine B
but angle B measures 180 degrees - 90 degrees - 30 degrees = 60 degrees
so AC = 40m sine 60 degrees
Choice A
@@csec-maths-chem-paper1sTyy!!
@@TwixMix you're welcome~
did you notice
in meters,
at first we calculated AC = 40 cos 30°
then we calculated AC = 40 sin 60°
which would have to mean that cos 30° = sin 60°
the co- in co-functions means complementary
and we see that 30° + 60° = 90°
so cos x° = sin (90° - x°)
also sin y° = cos (90° - y°)
Why is it 4 hrs at 10:24 ?
lets say 23 : 00 h is 11 pm tonight
then 03 : 00 h is 3 am tomorrow
11 pm to midnight is +1 hour
midnight to 1 am is +1 hour
1 am to 2 am is +1 hour
2 am to 3 am is +1 hour
so altogether 4 hours has passed from the given times
@@csec-maths-chem-paper1s ooh ty!
Hi can you create link with all the pass papers
If you mean a playlist will all my solution vids
that's here:
czcams.com/play/PLjCZPg9qLWrL2gpo9n0oGd2R-qWUZpbiR.html
sorted in reverse chronological order
if you mean to my videos for each past paper that I posted solutions for
those are in the pinned comment under my answer key~
if you mean the pdf of the past papers themselves,
you can check a few sites for that
or just email me here: csec.chemistry.paper1@gmail.com
with subject like past papers csec maths p1s
and I'll send you all the Paper 1s I 've found online for CSEC Maths
that's the best I can do~
if you notice, no one with a yt channel has literally uploaded them in such a way
there's a legal issue with that
they're not ours to re-upload and create a link for like that~
I thought #14 was A.18.00
10% of 1800 means we just cross off one 0 at the end of the listed price
so it would be $180 for the discount
1% of 1800 means we would cross off two 0s at the end of the listed price
so that would be $18
1% is 1/100, so that's why we cross off 2 zeroes
but a 1% sale isn't much is it?!
10% would be more attractive to customers
10% is 0.1, so 10% of 1800 is 0.1 x 1800 = 180
1% is 0.01, so 1% of 1800 is 0.01 x 1800= 18
Heyy, 60 is D
If 2 sides are equal and a triangle equals 180° (since its 2 equal sides and the value is unknown its x+x or 2x) so,
2x +y = 180
Therefore y= 180-2x
lets pretend x is 100 degrees, you're telling me there is a triangle with negative 20 degrees?
only one angle of the described triangle will have a measure of x degrees
it would be
x + y + y = 180
x + 2y = 180
2y = 180 - x
we're trying to find the y angles
so y = half of (180 - x)
angle R and angle Q measure y degrees
@@csec-maths-chem-paper1s in a isosceles triangle one of the equal sides cannot be 100° as that therefore means that you'll need to add it twice which will lead to 200° which is impossible sir/ma'am
the base angles are opposite the congruent sides
which are the two line segments meeting at vertex P forming angle x
