Quadrilateral ABCD Is Reflected Over The X-axis. What Are The Coordinates Ofquadrilateral A'B'C'D?

Answers

Answer 1

Answer: A

Step-by-step explanation:

X values to the right of the y axis are positive. X values to the left of the y axis are negative.

Y values above the x axis are positive.

Y values below the x axis are negative.

Pairs of coordinates are always noted as (x,y) with the x value of a point given first and the y value of that same point given second.

Answer 2

Answer:

A

Step-by-step explanation:

Let A=(a,b) then the reflected over the x-axis will be A'=(a,-b)

A=(5,5) --> A'=(5,-5)

B=(5,1) --> B'=(5,-1)

C=(2,1) --> C'=(2,-1)

D=(1,5) ---> D'=(1,-5)

Find the equation of the line through the points (-8,3) and (-4,5).

Answers

Answer:

[tex]2y - x = 14[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (-8,3)[/tex]

[tex](x_2,y_2) = (-4,5)[/tex]

Required

The line equation

First, calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{5 - 3}{-4 - (-8)}[/tex]

[tex]m = \frac{2}{4}[/tex]

[tex]m = \frac{1}{2}[/tex]

The equation is then calculated as:

[tex]y = m(x - x_1) + y_1[/tex]

[tex]y = \frac{1}{2}(x - (-8)) +3[/tex]

[tex]y = \frac{1}{2}(x +8) +3[/tex]

Open bracket

[tex]y = \frac{1}{2}x +4 +3[/tex]

[tex]y = \frac{1}{2}x +7[/tex]

Multiply through by 2

[tex]2y = x + 14[/tex]

[tex]2y - x = 14[/tex]

Find the volume of a pyramid with a square base, where the perimeter of the base is 7.4 ft and the height of the pyramid is 8.1 ft. Round your answer to the nearest tenth of a cubic foot.

Answers

9514 1404 393

Answer:

  9.2 ft³

Step-by-step explanation:

The side length of the square base is 1/4 of the perimeter, so is ...

  s = P/4 = (7.4 ft)/4 = 1.85 ft

The area of the base is the square of this, or ...

  A = s² = (1.85 ft)² = 3.4225 ft²

The volume of the pyramid is given by ...

  V = 1/3Bh = (1/3)(3.4225 ft²)(8.1 ft) = 9.24075 ft²

The volume of the pyramid is about 9.2 cubic feet.
