The equations for the coordinates of the endpoint F should be x = 2 · 35 - 15 and y = 2 · (- 3) - 26.

<h3>How to derive the equations for the missing endpoint of a line segment</h3>

In this problem we know the coordinates of the endpoint E and the midpoint M of the line segment EF and we need to derive expressions of the coordinates of the endpoint F by the midpoint formula:

M(x, y) = 0.5 · E(x, y) + 0.5 · F(x, y)

2 · M(x, y) = E(x, y) + F(x, y)

F(x, y) = 2 · M(x, y) - E(x, y)

If we know that M(x, y) = (35, - 3) and E(x, y) = (15, 26), then the coordinates of the endpoint F are:

F(x, y) = 2 · (35, - 3) - (15, 26)

F(x, y) = (70, - 6) + (- 15, - 26)

F(x, y) = (55, - 32)

The equations should be x = 2 · 35 - 15 and y = 2 · (- 3) - 26.

The equation D=13/v shows that the density of a particular substance equals a mass of 13 grams divided by the volume of the subs
lions [1.4K]
For this case we have the following equation:
 D =  \frac{13}{v}
 Where,
 D: t<span>he density of a particular substance 
 v: </span><span> the volume of the substance
 </span>When replacing v = 0 in the given equation we have:
 D = \frac{13}{0}
 D =  \infty
 This means that as the function acquires values very close to zero, the density acquires a very large value.
 Answer:
 
as the volume approaches 0:

Find an equation for the perpendicular bisector of the line segment whose endpoints are (5,-9) and (1,3).
____ [38]

Given coordinates of the endpoints of a line segment  (5,-9) and (1,3).

In order to find the equation of perpendicular line, we need to find the slope between given coordinates.

Slope between (5,-9) and (1,3) is :

\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

m=\frac{3-\left(-9\right)}{1-5}

m=-3

Slope of the perpendicular line is reciprocal and opposite in sign.

Therefore, slope of the perpendicular line = 1/3.

Now, we need to find the midpoint of the given coordinates.

\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)

=\left(\frac{1+5}{2},\:\frac{3-9}{2}\right)

=\left(3,\:-3\right)

Let us apply point-slope form of the linear equation:

y-y1 = m(x-x1)

y - (-3) = 1/3 (x - 3)

y +3 = 1/3 x - 1

Subtracting 3 from both sides, we get

y +3-3 = 1/3 x - 1 -3

<h3>y = 1/3 x - 4 .</h3>
