The Dangerous of Using Drugs
Everybody must pay attention of drugs. Drugs are very dangerous for us. Why it is very dangerous for us? Because its can caused harm to our body.
In terms of health, many organs in our body can be harm because using drug. In general, the impact of using drug are can unconscious, make us hallucinate, can harm our nerve, and cause addictive effect. Beside that, using drugs can make the users depressed, liver disease, schizophrenia, blockage of blood vessels, dehydration, optic nerve damage, brain damage, and finally it can cause DEATH!
When viewed in terms of Islamic law, drugs are forbidden. Because it is cause badness, self harm, debilitate. And Islam proscribes all that can cause badness, self harm because it is included zhalim. Also if we using drugs, it means we already do the forbidden things in Islam, it means we sin. So, in terms of Islamic law, using drugs also dangerous.
Furthermore, if the users of drugs are teenagers, it can endanger their future, and endanger their homeland, their country. From the data, 32 percent of drugs users in Indonesia are teenagers, so, if many teenagers –in this case Indonesia- use drugs, it can be endanger this country, harm youth generation, whereas youths are nation expectation. If the youth using drugs, our nation can be destroy!
So, from now on we must pay attention of drugs, because it’s very dangerous, both in terms of health, religion (Islam), nationality and sta

Bapak/Ibu guru, tolong bantu saya ya. Trima Kasih:)
1. Diketahui angka 2, 3, 4, 5, 6, 7, dan 8. Tentukan banyak susunan bilangan ratusan tanpa ada angka yang berulang dengan syarat berikut:
a. lebih dari 400
b. kurang dari 600
c. antara 400 dan 800
2. Sebuah dadu dan sebuah mata uang logam dilemparkan. K = kejadian munculnya gambar pda mata uang, L= kjadian munculnya angka prima genap pada dadu. Apakah K & L saling lepas?
Diketahui angka 2, 3, 4, 5, 6, 7, dan 8. Tentukan banyak susunan bilangan ratusan tanpa ada angka yang berulang dengan syarat berikut:
P(G) = 1/2 , P(L) = 1/6 , P(G irisan L) = P(G ^L) = 1/12
ternyata P( G ^L) = P(G).P(L) kan ? apa kesimpulannya
pak/bu mohon bantuannya..., tolong dibuatkan analytical exposition tentang the disadvantages of tv advertisement..., jawaban ibu/bapak, sangat saya harapkan...., terima kasih.., ^^
try these texts:
We are writing to you because we are concerned about the way food is being advertised to children.
What we eat now affects our health in years to come. Bad dietary habits start while we are very young. For this reason, your government support health education that encourages a balanced healthy diet. Australians are encouraged to get the bulk of their nutrients from fresh fruits, vegetables, and wholegrain cereals, a lesser amount from foods high in fat, salt and sugar.
TV advertising to children presents a completely different message. Nearly 80% of food advertising pushes fatty snacks or sweets - the very foods that should be eaten least. To make matter worse, these ads take up much of the advertising time. This must be stopped.
TV advertising is powerful and influential. Parents, however strong-willed, find it hard to resit pressures created by this advertising. Children are least able to understand the tricks of the advertising industry.
For the hours when children are the main audience, TV advertising of foods must be made to reinforce, not undermine, the message about a balanced diet. We appeal to you, as Prime Minister, to take the lead in calling together the advertisers, TV networks, consumers and public health bodies to decide how this isn to be done.

We are writing to complain about ads on TV. There are so many ads, especially during our favourite programmes. We think they should be stopped for a number of reasons.
First, ads are nuisance. They go on for a long time and there are so many. Sometimes there seems to be more ads than programmes.
Second, ads are bad influence on people. They try to encourage people to buy unhealthy food like beer, soft drink, candy and chips. And they make people want things they do not really need and can not.
Finally, the people who make ads have too much say in what programmes people watch. That is because they want to put all their ads on popular programs that a lot of people watch. Some programmes which are not so popular get stopped because they do not attract enough ads, even though those programmes may be someone’s favourite.
For those reasons, we think TV station should stop showing ads. They interrupt programmes. They are bad influences on people, and they are sometimes put a stop to people’s favourite shows. We are sick of ads, and now we mostly watch other channels.
1. Pada tumbukan elastis sebagian berlaku ?
a. Hokum kekekalan energy mekanik
b. Hukum kekekalan energy kinetic
c. Hukum kekekalan momentum
d. Jawaban a dan c benar
e. Jawaban b dan c benar
2. Sebuah kereta mainan bermassa 3 kg menumbuk dinding secara tegak lurus dgn laju 2 m/s dan dipantulkan dgn laju 1 m/s. besar impuls yg dilakukan oleh dinding pd kereta selama tumbukan adlh ?
3. Benda A dan B bertumbukan sentral di atas bidang datar horizontal licin. Besar kecepatan A, kecepatan B, massa A, dan massa B berturut-turut adalah 2 m/s, 2m/s, 5 kg dan 3 kg. jika tumbukan itu tidak elastic sama sekali
(1) Besar kec setelah tumbukan 0,5 m/s
(2) Energi kinetic A sebelum tumbukan 10 J
(3) Energi kinetic B sebelum tumbukan 6 J
(4) Energi total (A+B) setelah tumbukan 1 J
Pernyataan di atas yg benar adlh ?
a. (1)( 2) dan (3) d. (4) saja
b. (1) dan (3) e. semua benar
c. (2) dan (4)
mohon dijawab pertanyaannya bapak ibu guru
terima kasih
Pada setiap peristiwa tumbukan berlaku HUKUM KEKEKALAN MOMENTUM.
(1). m1.v1 + m2.v2 = (m1+ m2)v' maka v' = 0.5 m/s
(2) dan (3) Ek = 1/2 m v2
(3) Ek= 1/2 m v'2
Bapak/Ibu guru, mohon bantuannya untuk soal matematika saya (2 soal aja kok, makasi). Mohon uraiannya
a. (n+2)!
--------- = 2
(n+1)!
b. (n-1)!
--------- = 20
(n-3)!
n + 2 = 2
n = 0
(n - 1)(n -2) = 20
n2 - 3n + 2 = 20
n2 - 3n + 2 - 20 = 0
n2 - 3n - 18 = 0
(n +3) (n -6) = 0
n = - 3 atau n = 6, jadi n = 6
Bantuin ya bapak/ibu guru. Thx before :)
Senang bisa konsultasi di sini
Tentukan nilai n yang memenuhi
nC2 = 21, untuk n>0
mbak Melani , apa kabar ? akan saya mencoba menjawab :
nC2 = 21, untuk n>0
mbak melani ingat rumus kombinasi? nCr = (n !)/ n - r)! r!
sehingga nC2= 21
(n!)/ (n - 2).2! = 21
n. (n-1)(n - 2)!/ (n - 2)!.2 =21
n. (n-1)/2 = 21
n. (n-1) = 42
n2 - n - 42 = 0
( n + 6) (n - 7) = 0
n = -6 atau n = 7 , jadi n = 7
Buktikan :
[{cos 3x - sin 6x - sin 9x} : {sin 9x - cos 6x - sin 3x}] = tan 6x
Mbak Mega apa kabar ?, akan kami coba menjawab pertanyaan nya , rasanya ada yang salah tulis mbak,
{cos 3x - sin 6x - cos 9x} : {sin 9x - cos 6x - sin 3x} = tan6x
{(cos 3x - cos 9x)- sin6x} : {(sin 9x - sin3x) - cos 6x}= tan6x
{2sin 6x . sin 3x - sin6x} : {2 cos 6x sin 3x - cos 6x}= tan6x
( gunakan rumus cos A - cos B untuk yang pembilang dan sin A - sin B untukyg penyebut)
{2sin 6x . sin 3x - sin6x} : {2 cos 6x sin 3x - cos 6x}= tan6x
2 sin 6x( sin 3x - 1)
_______________ = tan 6x
2 cos 6x( sin 3x - 1)
sin 6x
_______________ = tan 6x ( terbukti )
cos 6x
minta dibuatkan soal tentang Gerak Parabola yang sering keluar di test, 10 saja. terima kasih
Mbak Asri, saya kira guru kamu mempunyai banyak bank soal tentang hal tersebut. Silahkan pendekatan dengan guru kamu.
