2. The parametric equations of a curve are given by x = 2 cos θ, y = sin² θ, 0 ≤ θ ≤ 2π. Find the values of θ when the tangent to the curve is parallel of the x-axis.
Jawaban:
[tex] \frac{\pi}{2}, \: \frac{3\pi}{2} [/tex]
Penjelasan dengan langkah-langkah:
[tex] \frac{dx}{dθ} = - 2 \: sin \: θ \\ \frac{dy}{dθ} = 2 \: sin \: θ \: cos \: θ \\ \frac{dy}{dx} = \frac{ 2 \: sin \: θ \: cos \: θ }{ - 2 \: sin \: θ } = - cos \: θ \\ [/tex]
When -cos θ = 0, then
[tex]θ = \frac{\pi}{2} \: and \: \frac{3\pi}{2} [/tex]

4. Find the value of m which the equation x^2+ (m – 3)x + 4 = 0 has two real roots.
• Persamaan Kuadrat
-
Nilai m agar x² + (m - 3)x + 4 = 0 memiliki 2 akar - akar real adalah m ≤ -1 atau m ≥ 7
• Pembahasan •
D ≥ 0 → Memiliki dua akar - akar reaL
x² + (m - 3)x + 4 = 0
a = 1
b = m - 3
c = 4
0 ≤ b² - 4ac
0 ≤ (m - 3)² - 4(1)(4)
0 ≤ m² - 6m + 9 - 16
0 ≤ m² - 6m - 7
0 ≤ (m + 1)(m - 7)
HP = { m ≤ -1 atau m ≥ 7 }
•••
-AL
Jawab:
m ≥ 7 atau m ≤ - 1
Penjelasan dengan langkah-langkah:
akan memiliki akar akar bilangan real jika D ≥ 0
bentuk umum persamaan kuadrat adalah ax² + bx + c = 0, maka dari soal diperoleh
a = 1
b = m - 3
c = 4
karena D ≥ 0, maka
D ≥ 0
b² - 4ac ≥ 0
(m-3)² - 4.1.4 ≥ 0
m² - 6m + 9 - 16 ≥ 0
m² - 6m - 7 ≥ 0
(m - 7)(m + 1) ≥ 0
maka didapat m ≥ 7 atau m ≤ -1
jadi, HP = {m | m ≥ 7 atau m ≤ - 1}

6. If p = 2 is a solution of the equation 2p - hp +6=0, find the value of h. Hence, find the other solution for the equation.
remember p = 2
Then,
2p² - hp + 6 = 0
2(2)² - h(2) + 6 = 0
2(4) - 2h + 6 = 0
8 + 6 - 2h = 0
14 - 2h = 0
2h = 14
h = 7
so, we have solution h is a 7
7. Given quadratic equation y = -×2-x+20a. Find what is the zero value
Using the quadratic formula
[tex] \frac{ - b \: ± \sqrt{ {b}^{2} - 4ac } }{2a} [/tex]
[tex]x = \frac{ - ( - 1)± \sqrt{( - 1 {)}^{2} - 4( - 1)(20)} }{2( - 1)} = [/tex]

9. Find the value of x and y from these given equations. x = 2y and 2x + 2y = 30.
Penjelasan dengan langkah-langkah:
Substitusi ya :)
2x + 2y = 30
2(2y) + 2y = 30
6y = 30
y = 5
x = 2(5) = 10
Penjelasan dengan langkah-langkah:
So, the value of x is 10 and y is 5. I Hope it could helps your homework :)

15. Given the equation linear two variable x = 7y x – y = 36 The value of 3x - 4y is . . . .
102 menggunakan eliminasi dan subtitusi
Jawab:
102
Penjelasan dengan langkah-langkah:
Pertama, cari nilai dari y dengan cara mengeliminasi x:
[tex]x = 7y\\x - y = 36\\\\x - 7y = 0\\x - y = 36\\============-\\-6y = -36\\y = 6[/tex]
Kedua, cari nilai dari x setelah mendapatkan nilai dari y dengan cara substitusi nilai dari y ke salah satu persamaan:
[tex]x = 7y\\x = 7 \times 6\\x = 42[/tex]
Ketiga, substitusikan nilai dari x dan y pada 3x - 4y:
[tex]3x - 4y\\\\= 3 \times 42 - 4 \times6\\\\= 126 - 24\\\\= 102[/tex]

19. 3n and 3n+3 are the two consecutive multiples of three. the sum ofbthe number is 141.write down and equation to show thissolve the equation to find the value of nwork out the values two initial numbers
Penjelasan dengan langkah-langkah:
3n and 3n+3 are the two consecutive multiples of three.
The sum of the number is 141.
__________________________
Write the equation:
3n + 3n + 3 = 141
6n + 3 = 141
________________________________
Solve the equation to find the value of n
6n + 3 = 141
6n = 141 - 3
6n = 138
n = 138/6
n = 23
_________________________________
Find the value of the consecutive multiples of three.
3n = ...
3(23) = 69
3n + 3 = ...
3(23) + 3 = ...
69 + 3 = 72
