Step-by-step explanation:

     The advantages of writing the polynomial expression

      -7x^{2} + 32x + 240 in factored form when interpreting this

      situation

      Factorizing the quadratic equation gives

       -7x^{2} + 32x + 240

        -7x^{2} +60x - 28x + 240

        x×(-7x + 60) -4 ×(-7x + 60)

        (x-4)×(-7x + 60)

        The roots of the equation<em> 4,-60/7</em>

        <em>Advantages of writing the polynomial expression in factored </em>

  • <em> we directly know the roots </em>
  • <em> we can easily draw the graph of the quadratic</em>

Anna11 [10]

You'd have 25 6/8 yards of wire left because she took 3 yards from each spool. So that gives us 2 spools of 12 7/8 and when you add them you get 25 6/8.

Match the real-world descriptions with the features they represent within the context of Melissa’s garden. Not all tiles will be
ycow [4]

The features in a function can be used to describe real-world events. The features and their match are:

  • <em>domain: all possible lengths of the tomato patch</em>
  • <em>y - intercept: area of the bell pepper patch when the length of the tomato patch is 0 </em>
  • <em>x - intercept: length of the tomato patch when the area of the bell pepper patch is 0</em>
  • <em>range: all possible areas of the bell pepper patch</em>

<em />

For Melissa's garden, the input and output variables are:

  • <em>Input: tomato patch</em>
  • <em>Output: bell pepper patch</em>

The range is the list of possible output values, while the domain is the list of possible input values.

This means that: the range is all possible areas of the bell pepper patch while the domain is all possible lengths of the tomato patch

Also, the x and y intercepts are when the values of the output and input variables are 0, respectively.

Using the above comparison;

The y - intercept is the area of the bell pepper patch when the length of the tomato patch is 0, while the x - intercept is the length of the tomato patch when the area of the bell pepper patch is 0.
