22. The height of a triangle is 4 centimeters less than the base. Write a function that

The function is y = 1/2 x² - 2 x and the base of the triangle cannot be 3 cm.

let the base of the triangle be x

Height of the triangle = x - 4

Area of triangle = 1/2 × base × height

Area = 1/2 × x × (x-4)

Area = 1/2 (x² - 4x)

Area = 1/2 x² - 2 x

We can also write it as a function:

y = 1/2 x² - 2 x

Domain = (3 , ∞)

Range = [0, ∞)

Since 3 is not included in the domain, base of the triangle cannot be 3 cm.

Therefore, the function is y = 1/2 x² - 2 x and the base of the triangle cannot be 3 cm.

Elizabeth has a swimming pool at home. She wants to build a deck all the way around her rectangular swimming pool. The width of
galben [10]

Using the perimeter of a rectangle, it is found that she can make a deck of 122 ft wide.

<h3>What is the perimeter of a rectangle?</h3>

The perimeter of a rectangle of length l and width w is given by:

P = 2(l + w)

In this problem:

  • She has enough wood to build a deck that is 280ft, hence P = 280.
  • The length is of 10 feet, hence l = 10.
  • Considering that the deck's width will be added to the actual width of 8 feet, we have that w = 8 + w.

Then:

P = 2(l + w)

280 = 2(10 + 8 + w)

36 + 2w = 280

2w = 244

w = \frac{144}{2}

w = 122

She can make a deck of 122 ft wide.
