Answer:

Step-by-step explanation:

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

t² + 12² = 13²

t² + 144 = 169 ( subtract 144 from both sides )

t² = 25 ( take the square root of both sides )

t = $\sqrt{25}$ = 5 → A

Solve s=2(lw+lh+wh) for w

Scilla [17]

   s = 2(lw + lh + wh)

Divide each side by 2 :    s/2 = lw + lh + wh

Subtract 'lh' from each side:       s/2 - lh = lw + wh

Combine the 'w' terms:      s/2 - lh = w(l + h)

Divide each side by (l + h): (s/2 - lh) / (l + h) = w

The graph below shows a company’s profit f(x), in dollars, depending on the price of the erasers x, in dollars, being sold by th

Alex777 [14]

The x-intercept = (0, 0) and (8, 0), Rate of function is 50 and as the price of erasers increasing the company's profit increasing and when price of the eraser decreasing the price the company's profit decreasing.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a graph of a function:

From the graph:

x-intercept = (0, 0) and (8, 0)

Maximum value of the graph = 270 at x = 4

Increasing in the interval x ∈ (0, 4)

Decreasing in the interval x ∈ (4, 8)

As the price of erasers increasing the company's profit increasing and when price of the eraser decreasing the price the company's profit decreasing.

Rate of function = (270-120)/(4-1) = 50

Thus, the x-intercept = (0, 0) and (8, 0), Rate of function is 50 and as the price of erasers increasing the company's profit increasing and when price of the eraser decreasing the price the company's profit decreasing.
