The question is :
Danielle reflects shape S in the line x = - 1 , and then reflects the new shape in the line y = 2

Zachary reflects shape S in the line y = 2 , and then reflects the new shape in the line x = - 1

Work out the coordinates of the vertex that A maps to after

a) Danielle's two reflections.

b) Zachary's two reflections.
.

Answers

Answer 1

The coordinates of the vertex that A maps to after Daniel's reflections are (3, 4) and the coordinates of the vertex that A maps to after Zachary's reflections are (3, 2)

How to determine the coordinates of the vertex that A maps to after the two reflections?

From the given figure, the coordinate of the vertex A is represented as:

A = (-5, 2)

The coordinates of the vertex that A maps to after Daniel's reflections

The rule of reflection across the line x = -1 is

(x, y) ⇒ (-x - 2, y)

So, we have:

A' = (5 - 2, 2)

Evaluate the difference

A' = (3, 2)

The rule of reflection across the line y = 2 is

(x, y) ⇒ (x, -y + 4)

So, we have:

A'' = (3, -2 + 4)

Evaluate the difference

A'' = (3, 4)

Hence, the coordinates of the vertex that A maps to after Daniel's reflections are (3, 4)

The coordinates of the vertex that A maps to after Zachary's reflections

The rule of reflection across the line y = 2 is

(x, y) ⇒ (x, -y + 4)

So, we have:

A' = (-5, -2 + 4)

Evaluate the difference

A' = (-5, 2)

The rule of reflection across the line x = -1 is

(x, y) ⇒ (-x - 2, y)

So, we have:

A'' = (5 - 2, 2)

Evaluate the difference

A'' = (3, 2)

Hence, the coordinates of the vertex that A maps to after Zachary's reflections are (3, 2)

Given a line segment that contains the points A,B, & C in order, if AB = x + 12, and BC = 2x - 4, and AC = 26, find x.

Answers

Answer:

x = 6

Step-by-step explanation:

If A, B and C lies on a straight line in order, then;

AB+BC = AC

x+12+2x-4 = 26

x+2x+12-4 =26

3x+8 = 26

3x = 26-8

3x = 18

x = 18/3

x = 6

Hence the value of x is 6

If $30,000 then is equivalent to $900,000;
then, what is $1 then equivalent to in today's
dollars?

Answers

Answer:

$30

Step-by-step explanation:

You need to figure out how the money changes between then and now. To do that, take now and divide it by then; 900,000/30,000 = 30, the amount now is 30 times that of then. To figure out what any amount then is worth now, multiply it by 30 and you'll get you answer. (In this case: 1*30 = 30)

determine if JK and LM parallel, perpendicular, or neither .

Answers

Answer:

3 - Perpendicular.

4 - Parallel.

Step-by-step explanation:

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

[tex]JK = \frac{1-(-7)}{-4-(-10)} = \frac{8}{6} = \frac{4}{3}[/tex]

[tex]LM = \frac{-2-2}{-6-(-3)} = \frac{-4}{3}[/tex]

Perpendicular, because two lines are considered perpendicular if their slopes are opposite reciprocals.

[tex]JK = \frac{-2-(-2)}{3-11} = \frac{0}{-8} = 0[/tex]

[tex]LM = \frac{-2-(-7)}{1-1} = \frac{5}{0} = 0[/tex]

A right triangle has side lengths d, e, and f as shown below. Use these lengths to find sinx, tanx, and cosx.

Answers

Step-by-step explanation:

In the given triangle,

Perpendicular = d

Hypotenuse = e

Base = f

We need to find the values of sinx, tanx and cosx.

We know that,

[tex]\sin \theta=\dfrac{P}{H}\\\\\tan\theta=\dfrac{P}{B}\\\\\cos\theta=\dfrac{B}{H}[/tex],

We have, P = d, H = e and base = f

So,

[tex]\sin \theta=\dfrac{d}{e}\\\\\tan\theta=\dfrac{d}{f}\\\\\cos\theta=\dfrac{f}{e}[/tex]

Hence, this is the required solution.

Using the lengths given, the Trigonometry ratios of the right triangle are:

sin x = d/e cos x = f/etan x = d/f

Recall:

In a right triangle where we are given a reference angle, ∅, with three sides, we can solve the triangle using the Trigonometry ratios given as: SOH CAH TOA.

Given the following:

∅ = xOpposite = dHypotenuse = eAdjacent = f

Thus:

sin x = Opp/Hyp = d/e (SOH)

cos x = adj/Hypo = f/e (CAH)

tan x = Opp/Adj = d/f (TOA)

Therefore, using the lengths given, the Trigonometry ratios of the right triangle are:

sin x = d/e cos x = f/etan x = d/f

Answer:

Step-by-step explanation:

-9 divided by +3 can be written as -9 divided by 3, because when you have a positive number, you don't have to write a plus sign in front of it. Next, we can just do 9/3 and then add the negative sign to the result to get our answer. 9 divided by 3 is equal to 3, and when you add the negative sign, you get -3.
