Figure ABCDE has vertices a(-3, 3), b(2, 3), c(5, -2), d(0, -3), and e(-3, -2). Plot the points on your own coordinates grid and
Ilya [14]
<h2>Answer:</h2>

Shown below

<h2>Step-by-step explanation:</h2>

First of all, we have the following points:

a(-3, 3) \\ \\ b(2, 3) \\ \\ c(5, -2) \\ \\ d(0, -3) \\ \\ e(-3, -2)

To plot these points, we need to graph a coordinate grid. Recall that a coordinate grid is composed of two perpendicular lines, that we call the axes and are labeled like number lines. The horizontal axis is called the x-axis while the vertical axis is called the y-axis, and these two axes intersect at a point called the origin. Next, let's plot each point as follows:

<h2>PART 1. Plot the points on your own coordinates grid and connect in alphabetical order. </h2><h2></h2>

Point a:

Let's stand at the origin and then move three units to the left and three units up. The resulting point is shown in the firs figure below.

Point b:

Let's stand at the origin and then move two units to the right and three units up. The resulting point is shown in the firs figure below.

Point c:

Let's stand at the origin and then move five units to the right and two units down. The resulting point is shown in the firs figure below.

Point d:

Let's stand at the origin and then move three units to down. The resulting point is shown in the firs figure below.

Point e:

Let's stand at the origin and then move three units to the left and two units down. The resulting point is shown in the firs figure below.

Next, let's connect connect the points in alphabetical order, so that the line are connected from a to b, from b to c, from c to d, from d to e and from e to a again. So the resulting graph is shown in the second figure. As you can see, this is an irregular pentagon.

<h2>PART 2. Decompose figure ABCDE into rectangles and triangles.</h2>

Every pentagon can be divided up into three triangles. Hence, from the third figure. the triangles are:

ΔABE

ΔBDE

ΔBCD

Since a rectangle is a quadrilateral whose angles are all right angles, then there is no chance to obtain a rectangle from ABCDE. To obtain a rectangle, we'd need other points and this is not what the problem asks.

What is the effect on the graph of the function f(x)= x when f(x) is replaced with f(-x)
Nina [5.8K]
All the x values are made negative

X = 4

F(x) = 2x
F(4) = 2(4)
F(4)= 8

X = 4 (still)

F(-x) = 2(-x)
F(-4) = 2 (-4)
F(-4) = -8

A spotlight is mounted on the eaves of a house 30 feet above the ground. A flower bed runs between the house and the​ sidewalk,
never [62]

Answer:

The ladder should be 34 feet long.

Step-by-step explanation:

The height of the spotlight above ground = 30 feet

The base of the ladder will be = 16 feet from the base of house

We can easily assume this to be a right triangle with perpendicular as 30 feet and base as 16 feet and we have to find the hypotenuse.

Lets say the length of the ladder or hypotenuse is = x

We will apply Pythagoras theorem here.

30^{2} +16^{2} =x^{2}

=> 900+256 =x^{2}

=> 1156 =x^{2}

=> x=\sqrt{1156}

So, x = 34

Hence, the ladder should be 34 feet long.
