A gardener has 60 feet of fencing to keep

Nimfa-mama [501]

Answer:

225 ft^2

Step-by-step explanation:

From what we have in the question, we have 60 ft of fencing

To maximize the area, we will need to have a square

For a square, the length of all sides are equal

Let us call one of the sides s

Thus, from the perimeter of the square;

4s = 60

s = 60/4

s = 15 ft

The area is thus, the product of the side length of the square

15 * 15 = 225 ft^2

Please help me!!!!!!!

Answer:

$f(x)=\sqrt{x+3}$
$f(x)=\dfrac{1}{(x-2)(x-4)}$

Step-by-step explanation:

a) It can be convenient to use the square root function as one being defined only for values greater than or equal to some number. Here, we need to shift that function 3 units to the left, so its domain is [-3, ∞).

$f(x)=\sqrt{x+3}$

b) One way to put holes in a function is to put vertical asymptotes there. This function can be defined to have vertical asymptotes at x=2 and x=4 so those values are excluded from the domain.

$f(x)=\dfrac{1}{(x-2)(x-4)}$

Explain how using basic facts can help you find 10×20×30×40 mentally?

Katena32 [7]

So all you have to do is take the first numbers of each multiple and multiply them.
1 x 2 x 3 x 4 = 24
Now you just add the 4 zeros to your answer.
240,000

Our answer even checks!
10 x 20 x 30 x 40 = 240,000

Good Luck! :)
