13. A contractor buys 8.2 square feet of sheet metal.

Veseljchak [2.6K]

Answer:

$x = \frac{183}{6.7}$ is the required equation.

The Per sq ft of sheet costs $ 27.31.

Step-by-step explanation:

The total amount of sheet purchased = 8.8 sq. ft

The amount of sheet used = 2. 1 sq ft.

The worth of remaining sheet = $183

Let us assume the cost per sq ft of sheet = $x

Now, the remaining sheet =

Amount of total sheet purchased- Amount of sheet used

= 8.8 sq. ft - 2. 1 sq ft. = 6. 7 sq. ft

So, the worth of the remaining sheet 6.7 sq ft is $183.

⇒ Worth of 1 sq ft of sheet = $183 /6.7 sq ft

or, $x = \frac{183}{6.7} = 27.31$

or x = $27.31

Hence, the Per sq ft of sheet costs $ 27.31.

HELPPPP what do I do exactly ?

MAXImum [283]

Answer:

Step-by-step explanation:

Note that the squaring function and the square root function are inverses of one another. If we make a list of perfect squares, we get {1, 4, 9, 16, 25, ...}. Then the square roots of these numbers are {1, 2, 3, 4, 5, ... }.

Continue making a table of values to plot. The first row has x=0, y=0; this reflects that the sqrt of 0 is 0.

Fill the first (x-) column with perfect squares and the second (y-) column with the square roots of these perfect squares:

x y

0 0

1 1

4 2

9 3

and so on.

Now plot the following on the graph: (1,1), (4,2), (9,3), ....

Starting at (0,0) and moving to the right (indicating increases in x), plot these points. (You'll soon run out of room.) Draw a smooth curve from (0,0) to connect these points. The result is a graph of the square root function.

The domain of this function is "the set of all real numbers ≥0" and the range is the same: "the set of all real numbers ≥0"
