Exercise Sheet Number 6

Mathematics

Answer:

21.78 square feet

Step-by-step explanation:

Let A be the area of the square.

Given.

A square piece of metal measures 56 inches on one side.

So the length of the square is 56 inches.

We know that area of the square is.

area=(length)^{2}

A=56^{2}

A= 3136\ inches^{2}

1\ in^{2} = \frac{1}{144}\ ft^{2}

Now, we divide area by 144 for feet.

A=\frac{3136}{144}

A=21.78\ feet^{2}

Therefore, the piece of the metal is contained 21.78 square feet.

What is the zero of the function represented by this graph?
eimsori [14]

9514 1404 393

Answer:

  x = -6

Step-by-step explanation:

The zero is where the graph crosses the line y=0 (the x-axis). It is also called the x-intercept.

That point is (-6, 0). The x-value there is -6.

__

Some folks like the x-value only; others like the ordered pair. Of course the y-value in the ordered pair is 0, which is what makes it a zero of the function.

If the perimeter is 86in and the length is 25 what is the width
cestrela7 [59]
The answer is 18 because to find the perimeter you have to add length+width+width+length so we know that the length is 25 so we add 25+25 which is 50. then we subtract 86-50 which is 36. so we do 36 divided by 2 which gets us 18. Hope this Helps! :)

A gardener wishes to design a rectangular rose garden with one side of the garden along a main road. The fencing for the 3 non-r
Reptile [31]

Answer:

There is no minimum cost for the fencing that can satisfy these conditions.

as the equation obtained for this problem is y = \frac{7x}{x-6}.

Step-by-step explanation:

let length of the rectangular rose garden be x

and breath of the rectangular rose garden be y

then the area of the garden = xy

cost of fencing a foot for the 3 non road sides = $6

and cost of fencing a foot for a road side = $8

total cost of fencing = 6x + 8x + 6y + 6y

so, total cost = 14x + 12y

cost of fencing for every square foot of the area =$2

So, 2xy = 14x + 12y

=> 2xy = 14x + 12y

Also, x and y has to satisfy x>0 and y>0

You can solve for y (or x if you prefer)

2xy-12y=14x

xy - 6y = 7x

y(x-6)=7x

y = \frac{7x}{x-6}

we can check that this function has no minimum value.

as we increase x (starting any x > 6 to make y positive) to make y minimal, y will decrease but the product xy will increase.

So, there is not a minimum cost for fencing that can satisfy these conditions.
