Determine whether the points lie on straight line.

wel

Answer:

A) Non-collinear- does not lies on straight line

B) Collinear- lie on straight line

Step-by-step explanation:

We have to check collinearity of three points.

The points $(x_1, y_1, z_1),(x_2, y_2, z_2),(x_3, y_3, z_3)$ are said to be collinear if,

$\left[\begin{array}{ccc}x_1&y_1&z_1\\x_2&y_2&z_2\\x_3&y_3&z_3\end{array}\right] = 0$

A) A(2, 5, 3), B(3, 7, 1), C(1, 4, 4)

$\left[\begin{array}{ccc}2&5&3\\3&7&1\\1&4&4\end{array}\right] \\\\=2(28-4)-5(12-1)+3(12-7)\\= 8 \neq 0$

Thus, the given points are not collinear.

B) D(0,-5,5), E(1,-2,4), F(3,4,2)

$\left[\begin{array}{ccc}0&-5&5\\1&-2&4\\3&4&2\end{array}\right] \\\\=0(-4-16)+5(2-12)+5(4+6)\\=0$

Thus, the given points are collinear.

On one side of a football stadium are 30 suites on the circle level. Fourteen of the suites have 24 seats each, and the rest hav

hram777 [196]

<span>The simplest form of a fraction occurs when the numerator and denominator cannot get any smaller (while still being integers)

In the stadium there are 30 suites.

14 suites.............24 seats
16 suites..............18 seats

The suites with 24 seats are 14 out of 30 which can be represented as 14/30.

However, the simplest fraction would be

7*2 7
------- = ------
15*2 15

This is why Tyler is incorrect</span>
