Geraldine has 200 feet of fencing. She wants to fence in a rectangular area. Which function A(w) represents the area of land tha
Brut [27]

Answer:

A(w) = - w^{2} + 100w

Step-by-step explanation:

First,  we need to find down the length (l) of the rectangular area in term of w

We have 200 feet of fencing is the perimeter of the rectangular area, which mean:

2 (w + l) = 200

<=> l = 100-w

But the area of land: w*l

= w (100-w)

=- w^{2} + 100w

So, A(w) = - w^{2} + 100w

Graph the image of the given triangle under a dilation with a scale factor of 1/4 and center of dilation ​(0, 0)
schepotkina [342]

Answer:

The image in the attached figure

Step-by-step explanation:

we know that

The dimensions of the image of the given triangle are equal to the original dimensions of the pre-image multiplied by the scale factor

In this problem the scale factor is 1/4

The height of the pre-image is 4 units

The base of the pre-image is 8 units

Find out the dimensions of the image

The height of the image is (4)\frac{1}{4}=1\ unit

The base of the image is (8)\frac{1}{4}=2\ units

The image in the attached figure
