Given the midpoint and one endpoint of a line segment, find the other endpoint.
neonofarm [45]

Answer:

(-12 , 2)

Step-by-step explanation:

<u>GIVEN :-</u>

  • Co-ordinates of one endpoint = (-4 , -10)
  • Co-ordinates of the midpoint = (-8 , -4)

<u>TO FIND :-</u>

  • Co-ordinates of another endpoint.

<u>FACTS TO KNOW BEFORE SOLVING :-</u>

<em><u>Section Formula :-</u></em>

Let AB  be a line segment where co-ordinates of A = (x¹ , y¹) and co-ordinates of B = (x² , y²). Let P be the midpoint of AB . So , by using section formula , the co-ordinates of P =

(x , y) = (\frac{x^2 + x^1}{2} ,\frac{y^2 + y^1}{2} )

<u>PROCEDURE :-</u>

Let the co-ordinates of another endpoint be (x , y)

So ,

(-8 , -4) = (\frac{-4 + x}{2} , \frac{-10 + y}{2} )

First , lets solve for x.

=> \frac{x - 4}{2} = -8

=> x - 4 = -8 \times 2 = -16

=> x = -16 + 4 = -12

Now , lets solve for y.

=> \frac{y - 10}{2} = -4

=> y - 10 = -4 \times 2 = -8

=> y = -8 + 10 = 2

∴ The co-ordinates of another endpoint = (-12 , 2)

What are the zeros of the function f(x) = x2 + 8x + 4, expressed in simplest radical form?
KonstantinChe [14]

Answer:

x = - 4 ± 2\sqrt{3}

Step-by-step explanation:

Given

f(x) = x² + 8x + 4

To find the zeros, let f(x) = 0, that is

x² + 8x + 4 = 0 ( subtract 4 from both sides )

x² + 8x = - 4

Using the method of completing the square

add (half the coefficient of the x- term )² to both sides

x² + 2(4)x + 16 = - 4 + 16

(x + 4)² = 12 ( take the square root of both sides )

x + 4 = ± \sqrt{12} = ± 2\sqrt{3} ( subtract 4 from both sides )

x = - 4 ± 2\sqrt{3}
