For the graphing if for example it says (3,-9) then you start at the very middle called the origin. Then go to the right 3.(this is called the x-axis) then go down 9 (this is the y axis) stop there and put you point. I hope this kinda helps explain this to you better :/

You are saving money for a summer camp that costs $1800. You have saved $500 so far, and you have 14 more weeks to save the tota
Arlecino [84]

Answer:

$92.86

Step-by-step explanation:

Since it's AT LEAST 1800, the inequality sign would be ≥ 1800

Equation:

500 + 14x ≥ 1800

14x ≥ 1800 - 500

14x ≥ 1300

x ≥ 92.86

A woman wants to build a rectangular garden. She plans to use a side of a shed for one side of the garden. She has 84 yd of fenc
Ivan
Let x denote the length of the side of the garden which is covered fenced by a shed, and \frac{A}{x} be the width of the garden.

The perimeter of a rectangle is given by 2(length + width)
i.e. 2x + \frac{A}{x} = 84
which gives:
A = 84x - 2x^2

For the area to be maximum, the differentiation of A with respect to x must be equal to 0.
i.e. \frac{dA}{dx} =84-4x=0 \\ 4x=84 \\ x=21

Therefore, the maximum area of the garden enclosed is given by
84(21)-2(21)^2=1764-2(441)=1764-882=882 \, yd^2

A square garden plot has an area of 75 ft^2. Find the length of each side in simplest radical form. Calculate the length of each
Zinaida [17]
Hello.


The area of a square is calculated by the formula:

A = l²

As A = 75 ft², we have:

75 = l² 

l = √75

Now, note that: 75 = 3 . 25 = 3 . 5²

So:

l = √(3 . 5²) = √3 . √(5²)

<u>l =  5√3 ft</u>


Now, we can assume √3 = 1.73

l ≈ 5 * 1.732

l ≈ 8,7 ft   (Note that I have already put it in the nearest tenth)


OK :)
