1. Which equations represents a quadratic function? A. y = 3 + 2x2

Please help?!

Ugo [173]

draw a rectangle around it:

the widest part is from about -3 to 2 which is 5 units wide

height is from 3 to -4, which is 7 units

5*7 = 35

the top and bottom are angled so you can subtract a little for that

so I would estimate around 32 square units

Triangle ABC is shown Translate Triangle ABC 5 units left and 4 units up and reflect it over the x-axis

tekilochka [14]

Here is my process for solving this.

First I drew arrows that indicated I was moving the whole triangle 5 units to the left.

*Look at first attachment*

Then I drew another triangle using those new points. (The new triangle is in pink)

*Look at second attachment*

Then I drew arrows that moved this new triangle 4 units up. (The new arrows are in pink)

*Look at third attachment*

Then I drew the new triangle in blue using the new points.

*Look at fourth attachment*

Then I mirrored / reflected the triangle over the x axis (the horizontal line) In green.

*Look at fifth attachment*

The fifth attachment in green is the final product! Hope that helps.

Lupe’s Construction is building a rectangular house that is 16 feet longer than it is wide. They will be putting a 3-foot wide s

mr Goodwill [35]

Answer:

The length of the four pieces of protective strip is 96 feet

Step-by-step explanation:

Let the w be the width of the rectangular house and L is length. Since L = w + 16, its perimeter P = 2(w + L)

= 2(w + w + 16)

= 2(2w + 16)

Since the perimeter of the house P = 136 feet,

136 = 2(2w + 16)

dividing through by 2, we have

136/2 = (2w + 16)

68 = (2w + 16)

collecting like terms, we have

68 - 16 = 2w

52 = 2w

dividing through by 2, we have

w = 52/2

w = 26 feet.

Now, since the side walk is 3 foot wide all around, the width of the house plus sidewalk = w + 3 and the length of the house plus sidewalk = L + 3 = w + 16 + 3 = w + 19.

So, the perimeter of the house plus sidewalk which is the perimeter of the four pieces of protective strip is P' = 2(w + 3 + w + 19)

= 2(w + 22)

= 2(26 + 22)

= 2(48)

= 96 feet

So, the length of the four pieces of protective strip is 96 feet.

What is the square root of 96 Follow my new brainly at: fol

Ugo [173]

Answer:

4√6

Step-by-step explanation:

For right now, I will assume that the "Follow my new brainly at.." part is irrelevant.

Anyways, to find the square root of a number, usually the best way is to find its prime factorization first:

96 : $2^5\cdot \:3$

We can rewrite that as:

$\sqrt{2^4\cdot \:2\cdot \:3}$

Simplify!

$2^{\frac{4}{2}}\sqrt{2\cdot \:3}$

Since $2^{\frac{4}{2}}\sqrt{2\cdot \:3}$ is the same thing as $4\sqrt{6}$ , that is our answer.

Thusly, as seen above, the answer is $\boxed{4\sqrt{6}}$ .

Hope this helps! ((;
