Rectangle ABCD has vertex coordinates A(–1, –1), B(–1, –3), C(–4, –3), and D(–4, –1). It is translated 4 units to the right and

Vera_Pavlovna [14]

the translation takes the point A ( -1, -1) to (-1+4, 1) = (3, 1)

The refection in y = x 'flips' the points so (3, 1) becomes (1, 3) = A"

Do the same procedure for the other points to get the answer

(you should get B" = (-3, 3) )

What is the radius if the Diameter 10.5? r = 8.5 r = 5.25 r = 12.5 r = 21

nataly862011 [7]

If the diameter is 10.5 then the radius is 5.25.
This is because the radius of a diameter is half the diameter.

So

10.5/2
= 5.25

Therefore the radius is 5.25

find the equation of the perpendicular bisector of the line segment joining the points (3,8) and (-5,6).

IgorLugansk [536]

Answer:

y = - 4x + 3

Step-by-step explanation:

The perpendicular bisector is positioned at the midpoint of AB at right angles.

We require to find the midpoint and slope m of AB

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = A(3, 8) and (x₂, y₂ ) = B(- 5, 6)

m = $\frac{6-8}{-5-3}$ = $\frac{-2}{-8}$ = $\frac{1}{4}$

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{\frac{1}{4} }$ = - 4

mid point = [0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]

Using the coordinates of A and B, then

midpoint AB = [0.5(3 - 5), 0.5(8 + 6) ] = (- 1, 7 )

Equation of perpendicular in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

with m = - 4

y = - 4x + c ← is the partial equation

To find c substitute (- 1, 7) into the partial equation

Using (- 1, 7), then

7 = 4 + c ⇒ c = 7 - 4 = 3

y = - 4x + 3 ← equation of perpendicular bisector
