1. 3 Two vertices of a rectangle, ABCD, are A(-6, -4) and B(4, -8). Find the gradient of CD and the gradient of BC.

Two vertices of a rectangle, ABCD, are A(–6, –4) and B(4, –8).

The gradient of CD is –2/5 (or –0.4).The gradient of BC is 5/2 (or 2.5).

 

Penjelasan dengan langkah-langkah:

On rectangle [tex]ABCD[/tex]:

[tex]CD \parallel AB[/tex], and [tex]BC \perp AB[/tex], or [tex]BC\perp CD[/tex].

Thus, the gradient of [tex]CD[/tex] equals the gradient of [tex]AB[/tex], and the gradient of [tex]BC[/tex] equals –1/(the gradient of [tex]AB[/tex]) or –1/(the gradient of [tex]CD[/tex])

Solving them:

[tex]\begin{aligned}m_{CD}&=m_{AB}\quad\because CD\parallel AB\\&=\frac{y_B-y_A}{x_B-x_A}\\&=\frac{-8-(-4)}{4-(-6)}\\&=\frac{-4}{10}\\\therefore\ m_{CD}&=\boxed{\,\bf{-}\frac{2}{5}\,}\end{aligned}[/tex]

[tex]\begin{aligned}m_{BC}&=\frac{-1}{m_{AB}}\quad\because BC\perp AB\\&=\frac{-1}{m_{CD}}\quad\because BC\perp CD.\ {\sf too.\ }\\&=\frac{-1}{\left({-}\dfrac{2}{5}\right)}\\&=-1\times\left(-\frac{5}{2}\right)\\\therefore\ m_{BC}&=\boxed{\,\bf\frac{5}{2}\,}\\\end{aligned}[/tex]

17. show that (4,5,3), (1,7,4),and(2,4,6) are vertices of an equilateral triangle

Vektor (4, 5, 3), (1, 7, 4), dan (2, 4, 6) merupakan vektor dari segitiga sama sisi. Karena ketiga sisi segitiga tersebut sama besar yakni √14. Nilai tersebut diperoleh dari perhitungan panjang vektor pada segitiga. Simak pembahasan berikut.

Pembahasan

Diketahui:

A = (4, 5, 3)

B = (1, 7, 4)

C = (2, 4, 6)

Ditanya: apakah segitiga ABC merupakan segitiga sama sisi

Jawab:

Syarat segitiga ABC merupakan segitiga sama sisi adalah memiliki panjang sisi yang sama atau dapat ditulis sebagai berikut:

a = b = c

dengan:

a = panjang vektor BC atau |BC|

b = panjang vektor AC atau |AC|

c = panjang vektor AB atau |AB|

Menghitung panjang sisi a

a = panjang vektor BC atau |BC|, maka menghitung vektor BC terlebih dahulu.

vektor BC = C - B

vektor BC = (2, 4, 6) - (1, 7, 4)

vektor BC = (2 - 1, 4 - 7, 6 - 4)

vektor BC = (1, -3, 2)

Panjang vektor BC adalah:

|BC| = [tex]\sqrt{1^{2}+(-3)^{2}+2^{2}}[/tex]

|BC| = [tex]\sqrt{1+9+4}[/tex]

|BC| = √14

∴jadi panjang sisi a adalah √14.

Menghitung panjang sisi b

b = panjang vektor AC atau |AC|, maka menghitung vektor AC terlebih dahulu.

vektor AC = C - A

vektor AC = (2, 4, 6) - (4, 5, 3)

vektor AC = (2 - 4, 4 - 5, 6 - 3)

vektor AC = (-2, -1, 3)

Panjang vektor AC adalah:

|AC| = [tex]\sqrt{(-2)^{2}+(-1)^{2}+3^{2}}[/tex]

|AC| = [tex]\sqrt{4+1+9}[/tex]

|AC| = √14

∴jadi panjang sisi b adalah √14.

Menghitung panjang sisi c

c = panjang vektor AB atau |AB|, maka menghitung vektor AB terlebih dahulu.

vektor AB = B - A

vektor AB = (1, 7, 4) - (4, 5, 3)

vektor AB = (1 - 4, 7 - 5, 4 - 3)

vektor AB = (-3, 2, 1)

Panjang vektor AB adalah:

|AB| = [tex]\sqrt{(-3)^{2}+2^{2}+1^{2}}[/tex]

|AB| = [tex]\sqrt{9+4+1}[/tex]

|AB| = √14

∴jadi panjang sisi c adalah √14.

Karena panjang a = panjang b = panjang c = √14, maka terbukti bahwa segitiga ABC merupakan segitiga sama sisi.
