What is the y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1? y = (StartFraction

Dominik [7]

By applying section formula we got that y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is $\frac{5y_2+y_1}{6}$

<h3>What is section formula ?</h3>

Let point P(x,y) cuts line joining point $A(x_1,y_1)$ and $B(x_2,y_2)$ in $m_1:m_2$ then coordinate of point P is equal to $(\frac{m_1x_2+m_2x_1}{m_1+m_2}, \frac{m_1y_2+m_2y_1}{m_1+m_2})$

Here given that point divides line segment from J to K into a ratio 5:1

$m_1=5\\\\m_2=1$

Now we have to fin y coordinate of point that divides the directed line segment from J to K into a ratio of 5:1

We can calculated y coordinate by applying section formula as :

$\frac{5y_2+1y_1}{5+1}\\\\\frac{5y_2+y_1}{6}$

By applying section formula we got that y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is $\frac{5y_2+y_1}{6}$

When can we use the method of extracting the square root in solving the roots of quadratic equations?

viva [34]

Answer:

This is the “best” method whenever the quadratic equation only contains x2 terms.

The general approach is to collect all x2 terms on one side of the equation while keeping the constants to the opposite side.

step by step: but in order to solve a quadratic using the square root principle the problem must be in the correct form. To solve a quadratic using the square root principle the quadratic must be in vertex form, a(x – h)2 + k.
