Find the midpoint of the segment with the given endpoints. (9,9) and (6,8)

mars1129 [50]

Answer:

The mid-point is (7.5, 8.5).

Step-by-step explanation:

We are given two points (9,9) and (6,8) as the endpoints for a line segment and we are to find the midpoint of this segment.

We know that the formula for finding the mid point is:

Mid point = $(\frac {x_1 + x_1 }{ 2 } ,\frac { y_1 + y_2} {2} )$

So substituting the given values of the coordinates of the endpoints in the above formula to get:

$= (\frac {9 + 6}{2} , \frac {9 + 8}{2} )$

$= (\frac {15}{2} , \frac {17} {2} )$

$=(7.5, 8.5)$

Therefore, the mid-point is (7.5, 8.5).

Answer:

$x^2-4x+3$

$63\ \text{sq. units}$

Step-by-step explanation:

l = Length = $\dfrac{x^2-x-6}{x-5}$

w = Width = $\dfrac{x^2-6x+5}{x+2}$

Area is given by

$A=lw\\\Rightarrow A=\dfrac{x^2-x-6}{x-5}\times\dfrac{x^2-6x+5}{x+2}\\\Rightarrow A=\dfrac{x^2-3x+2x-6}{x-5}\times\dfrac{x^2-5x-1x+5}{x+2}\\\Rightarrow A=\dfrac{(x-3)(x+2)}{x-5}\times\dfrac{(x-5)(x-1)}{x+2}\\\Rightarrow A=(x-3)(x-1)\\\Rightarrow A=x^2-4x+3$

Area of the room is $x^2-4x+3$ .

If $x=10$

Area of the room

$A=x^2-4x+3=10^2-4\times 10+3\\\Rightarrow A=63\ \text{sq. units}$

So, the amount of carpet needed would be $63\ \text{sq. units}$ .
