Find an equation of the tangent line to the hyperbola y=3/x at the point (3, 1).
1. Find an equation of the tangent line to the hyperbola y=3/x at the point (3, 1).
Penjelasan dengan langkah-langkah:
y = 3x-1
m = -3/x² then m = -1/3
y -1 = -1/3(x - 3)
3y -3 = -x + 3
3y + x = 6

3. 7. There are rabbits and chickens on a farm. The number of their legs of rabbits is half the number of chickens. is 168. if the number How many rabbits are on the farm?
Jawaban:
Jadi maksudnya jumlah kaki kelinci itu setengahnya jumlah ayam dan jumlah itu adalah 168. Yang ditanya berapa jumlah kelinci???
kelinci punya 4 kaki jadi 168 dibagi 4
42 / forty-two
Penjelasan dengan langkah-langkah:
legs of Chickens = x
legs of Rabbits = y
x = 2y
x+y =168
(2y)+y=168
y=56
rabbits=56:4 =14

5. The sum of half of a number and 49 is 2¼ of the numbers. Find the number.
Jawab:
28
Penjelasan dengan langkah-langkah:
Ini kita bikin persamaan matematikanya dulu, ya. Baru dicari =
1/2x + 49 = 2 1/4x
1/2x + 49 = 9/4x (dikali 4)
2x + 196 = 9x
196 = 9x - 2x
196 = 7x
28 = x
Semoga membantu, yaa.

the surface area of pendulum =
[tex]2\pi. {r}^{2} + \pi.r.s[/tex]
= 2. 3,14. 100 + 3,14 . 10.20
= 628 + 628

9. Given that the length of a rectangle is three times of the width. If the area of the rectangle is 192 cm2, then a half of the perimeter of its rectangle is…cm
l = 3w
l.w = A
(3w).w = 192
[tex]3{w}^{2} = 192 \\ {w}^{2} = \frac{192}{3} [/tex]
[tex]w = \sqrt{ \frac{192}{3} } = \sqrt{64} = 8[/tex]
l=3(w) = 3(8) = 24
(1/2) p = (1/2) 2(l+w)
= l + w = 24+8 = 32 cm
10. On a farm, there are only sheep and cows. The number of sheep is 8 more than the number of cows. The number of cows is half the number of sheep. How many animals are on the farm?
Penjelasan dengan langkah-langkah:
s = 8 + c
c = s/2
s = 8 + s/2
2s = 16 + s
s = 16
c = s/2
c = 16/2
c = 8
total = s + c
total = 16 + 8
total = 24

12. The length of a cuboid is 8 cm and its breadth is 3 cm. The height of the cuboid is half the length of its base. Find the volume of the cuboid.
Jawaban:
96 cm³
Penjelasan dengan langkah-langkah:
Panjang = 8cm
Lebar = 3cm
Tinggi = ½panjang = ½ × 8 = 4cm
Volume = P x L x T
Volume = 8 × 3 × 4
Volume = 96 cm³

15. . The angle of half circle is ...
The angle of a half circle is 180°.
[tex]\\[/tex]
EXPLANATIONA circle has an angle of 360°. Cut it in half and you would get two half circles with each one of them has an angle of 180°. Cut one in half and you would get two quarter circles. We know that a quarter circle has an angle of 90°.
So, with basic arithmetic we can find the solution to the problem; The angle of a half circle is a hundred and eighty degrees (180°) because three hundreds and sixty, which is the angle of a circle in degrees, divided by two is equal to a hundred and eighty (360/2 = 180).

18. Look at the metal pendulum. The metal pendulum consists of a cone and a half sphere. If the radius of the half sphere is 10 cm and the slant height(apothem) of the cone is 20 cm, the surface area of the pendulum is....cm²
Lp pendulum = Lp 1/2 bola + Lp kerucut tanpa alas
L = 1/2 . 4 . phi . r² + phi. r . s
L = 2 . 3,14 . 10² + 3,14 . 10 . 20
L = 1256cm²
19. The metal pendulum consist of a cone and a half sphere if the radius of the half sphere is10 cm and the slant height (apothem) of the cone is 20 cm the surface area of the pendulum is
lpkerucut=phi×r(r+s)
