8. in each of the following figures ab//cd.Find the values(s) of the unknown(s)
(a). b? a?
Segitiga memiliki total 180°, karena itu:
180°-(30+38) = 180-68 = 112°
4b = 360°-(112×2) = 360-224 = 136°
b = 34°
a = 180 - 38 = 142°
(b). d? c?
140° = 7c
20° = c
2d = 7c = 140°
d = 70°
(c). e?
7e + 3e = 180° = 10e
e = 18°
(d). f?
2f+6 = 3f-23
-f = -29
f = 29°
9. Find the values of p
f(x) = -x² + 14x + p²
a = -1
b = 14
c = p²
y max = 74
(b² - 4ac)/(-4a) = 74
[14² - 4 . (-1) . p²]/[-4 . (-1)] = 74
(196 + 4p²)/4 = 74
196 + 4p² = 74 . 4
196 + 4p² = 296
4p² = 296 - 196
4p² = 100
p² = 100 : 4
p = ±√25
p = ±5
10. given f(x)= [tex] 2^{x} [/tex] find the values of
[tex]\text{Bagian A} \\ f(x)~=~2^x \\ f(4x+3)~=~2^{4x+3} \\ f(2x-1)=2^{2x-1} \\ f(6x-3)~=~2^{6x-3} \\ \text{Maka~:} \\ \\ \displaystyle \frac{f(4x+3)~\bullet f(2x-1)}{f(6x-3)}~~=~~\frac{2^{4x+3} \bullet 2^{2x-1} }{2^{6x-3}}~~=~~2^{(4x+3)+(2x-1)-(6x-3)} \\ \\ \frac{f(4x+3)~\bullet f(2x-1)}{f(6x-3)}~~=~~2^{5}~=~32[/tex]
[tex]\text{Bagian B} \\ f(2x+1)~=~2^{2x+1} \\ f(x-3)~=~2^{x-3} \\ f(3x+5)~=~2^{3x+5} \\ \\ \displaystyle \frac{f(2x+1)~\bullet~f(x-3)}{f(3x+5)}~~=~~\frac{2^{2x+1}~\bullet~2^{x-3}}{2^{3x+5}}~=~2^{(2x+1)+(x-3)-(3x+5)} \\ \\ \\ \frac{f(2x+1)~\bullet f(x-3)}{f(3x+5)}~~~=~~2^{-7}~=~\frac{1}{2^7}~=~\frac{1}{128}[/tex]
11. find the values of unknown in each of the following Parallelogram. JANGAN ISENG!! iseng = report ,pls bantu ya lagi butuh‼️
cari nilai x°
jumlah sudut pada segitiga yaitu 180°, dengan demikian
x° + (180° - 139°) + 112° = 180°
x° + 41° + 112° = 180°
x° = 180° - 41° - 112°
x° = 27°
cari nilai y°
karena sudut D dan sudut B adalah sudut dalam bersebrangan, maka y° + x° = 68°, dengan demikian
y° + x° = 68°
y° + 27° = 68°
y° = 41°
so, the values of unknown in each of the following Parallelogram are x° = 27° and y° = 41°
12. Find the value of each of the following binary numbers, giving the values in decimal numbers:a)101b)1011c)10101•P͟a͟k͟a͟i͟ c͟a͟r͟a͟•Ja͟n͟g͟a͟n͟ n͟g͟a͟s͟a͟l͟
Jawaban:
a. 101 = 2^2 + 0 + 2^0 = 5
b. 1011 = 2^3 + 0 + 2^1 + 2^0 = 11
c. 10101 = 2^4 + 0 + 2^2 + 0 + 2^0 = 21
13. The diatance between the points (14,0) and ( 5 , y ) is 15 units , find the possible values of y
Jawaban:
y=12
Penjelasan dengan langkah-langkah:
Jarak antara titik (14,0) dan (5,y) adalah 15 satuan, tentukan nilai y yang memungkinkan
---------------------------------------------------------------------
(5-14,y-0)
=(-9,y)
Jarak terdekat antara dua titik menggunakan pitagoras
c²=a²+b²
a²=c²-b²
[tex]a = \sqrt{ {c}^{2} - {b}^{2} } [/tex]
[tex]y = \sqrt{ {15}^{2} - {( - 9)}^{2} } [/tex]
[tex]y = \sqrt{225 - 81} [/tex]
[tex]y = \sqrt{144} [/tex]
y=12
14. 2. In the diagram, PRT and QRS are straight lines. Find the values of a and b.
Jawaban:
a= 75
b= 23
Penjelasan dengan langkah-langkah:
Cari PRQ:
= 180°-26°-79°
= 154°-79°
= 75°
Karena betolak belakang, maka a= 75.
180= a + b + 82
98= a + b
98= 75 + b
23= b
15. 3. Look at the following figure! in that figure, find the values of a, b, c, d, and e!
Jawaban:
a. 180° - 50° = 130°
b. 180° - 95° = 85°
c. 180° - 80° = 100°
d. 180° - 100° = 80°
e. jumlahnya sama dengan c karena berseberangan, yaitu 100°
16. The difference between the values of the two "4"s in thenumber 4346 is?
The 1st 4 from the left in number 4346 mean 4000, The 2nd 4 mean 40.
So the difference between them is
= 4000 - 40

18. Two similar toy houses are as shown. Find the values of the unknowns.
Penjelasan dengan langkah-langkah:
x = 100°
120/180 = 180/y
y = 180 x 180 : 120
y = 270 cm
z / 150 = 120 / 180
z = 150 x 120 : 180
z = 100 cm

20. Find the values of a and p in the following proportions! a. a : 5 = 16 :20 b. 6 : 5 = p : 30
a. a : 5 = 16 : 20
a = [tex] \frac{16 . 5}{20} [/tex] = 4
b. 6 : 5 = p : 30
p = [tex] \frac{6 . 30}{5} [/tex] = 36α = 16/20 x 5
= 16/4
= 4
p = 6/5 x 30
= 6 x 6
= 36
