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.

Answer:

The answer as a mixed number is =15\frac{3}{4}.

Step-by-step explanation:

Given:

5 1/4 ÷ 1/3.

Now, to solve as a mixed number in simplest form.

5\frac{1}{4} \div \frac{1}{3}

<em>Now, changing the mixed fraction into improper:</em>

=\frac{21}{4} \div \frac{1}{3}

So, to solve we change the division into multiplication.

Thus, R.H.S of the fraction will get reverse:

=\frac{21}{4} \times \frac{3}{1}

=\frac{63}{4}

<em>Now, changing the improper fraction into mixed:</em>

=15\frac{3}{4} .

Therefore, the answer as a mixed number is =15\frac{3}{4} .
