Answer:

(3,-8)

Step-by-step explanation:

It has to be (3,-8) because you must maintain the width and length of both sides.

A parabola can be drawn given a focus of (6,-1) and a directrix of y = 9. What can be said about the parabola?

zavuch27 [327]

Answer:

Since the focus is at (-6,-11) and the directrix is at y=9:

The vertex is halfway between the focus and the directrix, so the vertex is at (-6,-1). (Draw this on graph paper if that doesn't make sense.)

The general form (conics form) of a parabola: 4p(y-k)=(x-h)^2 (vertex is (h,k) and "p" is the distance between the focus and vertex (or between vertex and directrix)).

(h,k) = (-6,-1)

p = 10 (distance between focus and vertex), so 4p = 40.

Therefore:

40(y+1)=(x+6)^2

Or if you need to rearrange to "vertex form": y=(1/40)(x+6)^2 - 1

Which sequence of transformations will map figure K onto figure K′? Two congruent kites, figure K and figure K prime, are drawn

elixir [45]

Answer:

The sequence of transformations will map figure K onto figure K′

is the first sequence option (1)

======================================================

Step-by-step explanation:

See the attached figure

as shown in the figure the K' is the image of K by reflection over x-axis

But  We need to know which sequence of transformations will give the same result.

So, we will test the options by any point from K and its image from K'

i.e: we will test the options using the points (6,5) , (6,-5)

(6,5) ⇒ (6,-5)

option (1):

Reflection across x = 4, 180° rotation about the origin, and a translation of (x + 8, y)

(6,5) ⇒ (2,5) ⇒(-2,-5) ⇒ (6,-5)

option (2):

Reflection across x = 4, 180° rotation about the origin, and a translation of (x − 8, y)

(6,5) ⇒ (2,5) ⇒(-2,-5) ⇒ (-10,-5)

option (3):

Reflection across y = 4, 180° rotation about the origin, and a translation of (x + 8, y)

(6,5) ⇒ (6,3) ⇒ (-6,-3) ⇒ (2,-3)

option (4):

Reflection across y = 4, 180° rotation about the origin, and a translation of (x − 8, y)

(6,5) ⇒ (6,3) ⇒ (-6,-3) ⇒ (-14,-3)

As shown: The sequence of transformations will map figure K onto figure K′

is the first sequence option (1)

Total bill for repairs is 329.00

sergij07 [2.7K]

Answer:

3 hours was spent on labor

Step-by-step explanation:

Key skills needed: Creating an equation, Solving an equation

1) The total cost is 329.00 (or 329). The parts are 125.00 (or 125), and the labor is 68 per hour.

2) If we say h is the number of hours of labor, then we can create this equation --> $68h$ (or 68 multiplied by "h") 68h would be the cost of labor, and we need to find the number of hours (h) as a number.

3) We can create this equation --> $329 = 125 + 68h$

--> This equation can be made as the total cost (329) is equal to the parts (125) and the labor (68h)

4) Subtract 125 from both sides to get 68h by itself

--> 329 - 125 = 204 so 204 = 68h

--> Divide by 68 on both sides (204 divided by 68 is 3)

--> This means that h is 3.

Therefore, the number of hours spent on labor is 3.

Hope you understood and have a nice day!! :D
