Answer 2

AnsWer :

√a² - 2a + 17.

Solution :

We have, Distance of Point.

Let's Point be.

• A ( a , 7 )
• B ( 1 , 3 )
• x1 = a.
• x2 = 1.
• y1 = 7.
• y2 = 3.

$\tt \dagger \: \: \: \: \: D = \sqrt{ {x_2 - x_1}^{2} + {y_2 - y_1}^{2} }$

A/Q,

$\tt : \implies AB = \sqrt{ {(1 - a)}^{2} + {(3 - 7)}^{2} }$

$\tt : \implies AB = \sqrt{1+ {a}^{2} - 2a + 16 }$

$\tt : \implies AB = \sqrt{ {a}^{2} - 2a + 17.}$

Therefore, Our Equation become of distance AB is √a² - 2a +17.

Some Information :

• Section Formula.

$\tt \dagger \: \: \: \: \: \dfrac{m_1x_2 + m_2x_1}{m_1 + m_2}$

• Mid-point Formula.

$\tt \dagger \: \: \: \: \: \dfrac{x_1 + x_2 }{2}$

• Area of ∆.

$\tt \dagger \: \: \: \: \: \dfrac{1}{2} \times [x_1 + (y_2 - y_ 1) + x _2(y _ 3 - y_ 1) + x _ 3(y _1 - y _ 2) ]$
