10. 4) Which of the following represents all the possible values of x that satisfy the equation below? X X x − 3 2x 2 *
Nilai x memenuhi persamaan yaitu x = 0 atau x = 4. Soal ini berkaitan dengan materi mencari nilai x dari suatu persamaan.
Penjelasan dengan langkah-langkahDiketahui :
Koreksi soal, mungkin maksud Anda persamaan x/(x-3) = 2x/2
Ditanyakan :
Solusi dari permasalahan tersebut
Jawab :
Langkah 1
x / (x - 3) = 2x / 2
Jika dipindah ruas akan menjadi :
x . 2 = 2x . (x – 3)
Selanjutnya kita lakukan operasi
2x = [tex]2x^{2}[/tex] – 6x
0 = [tex]2x^{2}[/tex] – 8x
0 = 2x (x – 4)
x = 0 atau x = 4
Jadi, x yang memenuhi adalah x = 0 atau x = 4

13. Please help The equation of a curve is y=x^3+3x^2-9x+k, where k is a constant. i) Find the coordinates of the stationary points on the curve and their natures. ii) Find the values of k for which the curve has a stationary point on the x-axis. iii) Find the equation of the tangent to the curve at the point where the curve intersects the y-axis. iii) Find the set of values for x for which y=x^3+3x^2-9x+k is increasing function.
[tex]EQ\rightarrow\ y=x^3+3x^2-9x+k\\\\i.\\Stationary\ points:\\\ f(x)=x^3+3x^2-9x+k\\f'(x)=3x^2+6x-9\\f'(x)=0=3x^2+6x-9\\0=(3x-3)(x+3)\\x_1=1\\x_2=-3\\\\Nature:\\f'(x)=3x^2+6x-9\\f''(x)=6x+6\\for\ x=1\rightarrow\ f''(x)=12(positive)\\for\ x=-3\rightarrow\ f''(x)=-12(negative)\\hence\ x_2\ is\ the\ maximum\ point\ and\ x_1\ the\ minimum[/tex]
[tex]ii.\\subsititute\ x_1\ and\ x_2\ to\ f(x)\\x_1\rightarrow (1)^3+3(1)^2-9(1)+k=0\\k_{x_1}=5\\x_2\rightarrow (-3)^3+3(-3)^2-9(-3)+k=0\\k_{x_2}=-27[/tex]
[tex]iii.\\intersects \rightarrow\ x=0\\y=(0)^3+3(0)^2-9(0)+k\\y=k\\y=\ 5/-27\\f'(x)=3x^2+6x-9\\3(0)^2+6(0)-9\\hence\ m_{curve}=-9\\\\for\ k=5\\\rightarrow y-5=-9(x-0)\\\rightarrow y=-9x+5\\\\for\ k=-27\\\rightarrow y+27=-9(x-0)\\\rightarrow y=-9x-27[/tex]
[tex]iv.\\because\ x_2\ is\ the\ maximum\ point,\\the\ function\ will\ incerase\ up\ to\ that\ point.\\\\because\ x_1\ is\ the\ minimum\ point,\\the\ function\ will\ decrease\ up\ to\ that\ point.\\\\Hence,\ the\ set\ values\ for\ x\ which\ f(x)\ is\ incerasing\ are:\\(-\infty,-3)\ and\ (1,\infty)[/tex]
hope these helps :)
14. What is y- intercept point of the graph below?
Jawaban:
(0,-6)
Penjelasan dengan langkah-langkah:
ingat bahwa y- intercept point (titik potong sumbu y) adalah titik yang memotong sumbu y (vertikal) dan titik bertemunya garis di x=0
lokasinya pada fungsi kuadrat adalah (0,c)
misal...
x² - 2x + 3
a = 1
b = -2
c=3
maka titik potong sumbu y adalah (0, 3)
--------
di grafik, titik potong sumbu y berada di (0,-6)

19. What is the velocity/time gradient graph for the oscillator ?
Jawaban:
The gradient of speed-time and velocity-time graphs represent acceleration. The area under a speed-time graph represents the distance travelled. Likewise, the area under a velocity-time graph represents the displacement of the moving object.
Penjelasan:
Gradien grafik kecepatan-waktu dan kecepatan-waktu mewakili percepatan. Area di bawah grafik kecepatan-waktu mewakili jarak yang ditempuh. Demikian juga, area di bawah grafik kecepatan-waktu mewakili perpindahan benda yang bergerak.
