10. The sum of three numbers in a particular arithmetic sequence is 33 and their product is 1287. Then, find the numbers that satisfied the sequence.
Jawab:
The numbers that satisfied the sequence are 9, 11, and 13.
Penjelasan dengan langkah-langkah:
If those three numbers are x, y, and z, then it is known that:
y - x = z - y ......(1) (rule of any arithmetic sequence)x + y + z = 33 .....(2)xyz = 1287 .....(3)From equation (1), we can get:
[tex]\begin{aligned}y-x &= z-y\\y-x-z+y&=0\quad\quad\text{(+z-y change\ side)}\\2y-x-z&=0\\\bf-x+2y-z&=\bf0\quad\dots\text{(4)}\end{aligned}[/tex]
The sum of equation (2) and (4) would be:
[tex]\begin{tabular}{r r r r c}x + &y + &z = &33&\ \\-x + &2y - &z = &0&\ \\\cline{1-4} &\\0 + &3y + &0 = &33&\ \\& & \bf y = & \bf 11\end{tabular}[/tex]
Substitute the value of y to equation (3):
[tex]\begin{aligned}xyz &= 1287\\11xz &= 1287\\xz &= 1287 \div 11\\\bf xz &= \bf 117\quad\dots(5)\end{aligned}[/tex]
Substitute the value of y to equation (2):
[tex]\begin{aligned}x+y+z&=33\\x+11+z&=33\\x+z&=33-11\\x+z&=22\\\bf z&=\bf 22-x\quad\dots(6)\end{aligned}[/tex]
And then, substitute the value of z from equation (6) to equation (5):
[tex]\begin{aligned}xz&=117\\x(22-x)&=117\\22x-x^2&=117\\-22x+x^2&=-117\quad\dots\text{($\times$ -1)}\\\bf x^2-22x+117&=\bf 0\quad\dots\text{(put them in order)}\\(x-9)(x-13)&=0\quad\dots\text{(factorization)}\\\bf x=9 \ \ or\ \ x&=\bf 13\end{aligned}[/tex]
At this point, we can guess that:
x = 9 and z = 13.
Let's verify this sequence:
9, 11, 13 : yes, this is an arithmetic sequencex + y + z = 9 + 11 + 13 = 33 : it is proved that the sum of these three numbers equals to 33.xyz = 9×11×13 = 99×13 = 1287 : it is also proved that their product is 1287.CONCLUSION:
The numbers that satisfied the sequence are 9, 11, and 13.
11. write one of the 'useful phrases' as an appropriate reaction to each of the following events from the script.
Answer:
In making an appropriate response or reaction, you need to look carefully at the expression or sentences used as well as its tone, whether it is meant to be humorous or serious one. Then, you can respond it in a creative way too, instead of just ordinary ones so long as appropriate. Here's the possible phrases to respond
- The cruel king has threatened to invade!
(Really? Then we'd better prepare ourselves. for normal reaction)
(What else is new? He's just bluffing. for unusual reaction)
- We are still alive; the soldiers are gone!
(Then we shall pray for them. They have fought bravely to protect us. (normal reaction)
(That's rather ironic for them. They should've been alive instead of us, who aren't trained for war. (uncommon reaction)
- The riddle is solved!
(At last! after a while - normal)
(Are you kidding me? what took you so long to solve such easy riddle - uncommon )
- We need a drum that sounds when nobody beats it!
(Such is impossible! - normal)
(Really? are you still in wonderland? - uncommon sardonic)
- Will the paper drum with the bee work?
(Huh, I don't get it - normal as it's unclear in meaning)

12. look at the following sequence 2 , 9 , 16 , 23 , 30 a. find the next two terms of the sequence final answer: b. find the general term of the sequence final answer: Tn = c. is 78 a term of the sequence? final answer (answer with yes or no) d. in which term/position will 632 appear in the sequence? final answer: ......... term
Jawaban:
a. 37, 44
b. Tn= 9+7n
c. no
d. 91
Penjelasan:
a. b= U2-U1= 9-2 = 7
maka angka selanjutnya adalah 30+7=37 dan 30+7.2=44
b. Tn=Un= a+b(n-1)
a= 2; b=7
maka Tn = 2+7(n-1) = 9+7n
c. (78-2)/7 akan menghasilkan sisa sehingga tidak termasuk
d. n= 1+[(632-2)/7] = 1+90 = 91
