Quadrilateral ABCD is inscribed in a circle.

cupoosta [38]

Answer:

$m\angle A=\boxed{135}\,^\circ$

Step-by-step explanation:

Opposite angles of an inscribed quadrilateral are supplementary, so ...

m∠A + m∠C = 180°

Substituting the given expressions, we have ...

(3x +6)° + (x+2)° = 180°

4x +8 = 180 . . . . . . collect terms, divide by °

x +2 = 45 . . . . . . . . divide by 4

3x +6 = 135 . . . . . . multiply by 3

This is the value of angle A in degrees, so ...

m∠A = 135°

Write the equation of a parabola having the vertex (1, −2) and containing the point (3, 6) in vertex form. Then, rewrite the equ

In-s [12.5K]

PART A

The equation of the parabola in vertex form is given by the formula,

$y - k = a {(x - h)}^{2}$

where

$(h,k)=(1,-2)$

is the vertex of the parabola.

We substitute these values to obtain,

$y + 2 = a {(x - 1)}^{2}$

The point, (3,6) lies on the parabola.

It must therefore satisfy its equation.

$6 + 2 = a {(3 - 1)}^{2}$

$8= a {(2)}^{2}$

$8=4a$

$a = 2$
Hence the equation of the parabola in vertex form is

$y + 2 = 2 {(x - 1)}^{2}$

PART B

To obtain the equation of the parabola in standard form, we expand the vertex form of the equation.

$y + 2 = 2{(x - 1)}^{2}$

This implies that

$y + 2 = 2(x - 1)(x - 1)$

We expand to obtain,

$y + 2 = 2( {x}^{2} - 2x + 1)$

This will give us,

$y + 2 = 2 {x}^{2} - 4x + 2$

$y = {x}^{2} - 4x$

This equation is now in the form,

$y = a {x}^{2} + bx + c$
where

$a=1,b=-4,c=0$

This is the standard form

The point Z(6,2) is rotated 180degrees clockwise around the origin.What arethe coordinates of the resulting point Z'

jok3333 [9.3K]

Answer:

$Z' = (-6,-2)$

Step-by-step explanation:

Given

$Z = (6,2)$

Transformation: 180 degrees clockwise around the origin

Required

Determine the new coordinates Z'

<em>When a point (x,y) is rotated 180 degrees clockwise around the origin, the new point is: (-x,-y)</em>

<em></em>

So:

$Z = (6,2)$

Then:

$Z' = (-6,-2)$
