What is the relationship between the discriminant of a quadratic and its graph?
faltersainse [42]

Answer:

In a quadratic equation of the shape:

y = a*x^2 + b*x + c

we hate that the discriminant is equal to:

D =  b^2 - 4*a*c

This thing appears in the Bhaskara's formula for the roots of the quadratic equation:

x = \frac{-b +-\sqrt{b^2 - 4ac} }{2a}

You can see that the determinant is inside a square root, this means that if D is smaller than zero we will have imaginary roots (the graph never touches the x-axis)

If D = 0, the square root term dissapear, and this implies that both roots of the equation are the same, this means that the graph touches the x axis in only one point, wich coincides with the minimum/maximum of the graph)

If D > 0 we have two different roots, so the graph touches the x-axis in two different points.

Rina8888 [55]

Answer: in explanation

Step-by-step explanation

Sandi can perform  1/9 of the task in a day

Eva can perform 1/5 of the task in a day

Working together, they can perform

                                                            1/9 + 1/5 of the task per day

                                                            = 5/45 + 9/45 = 14/45 of the task in a day

or                                                             45/14 days in the task = 3.2 days

So

          It would take about 3.2 days to complete the task working togethe
