What does the fundamental theorem of algebra illustrate?
UNO [17]

Answer:

The fundamental theorem of algebra guarantees that a polynomial equation has the same number of complex roots as its degree.

Step-by-step explanation:

The fundamental theorem of algebra guarantees that a polynomial equation has the same number of complex roots as its degree.

We have to find the roots of this given equation.

If a quadratic equation is of the form ax^{2}+bx +c=0

Its roots are \frac{-b+\sqrt{b^{2}-4ac } }{2a} and \frac{-b-\sqrt{b^{2}-4ac } }{2a}

Here the given equation is 2x^{2}-4x-1 = 0

a = 2

b = -4

c = -1

If the roots are x_{1} and x_{2}, then

x_{1} = \frac{-2+\sqrt{(-4)^{2}-4\times 2\times (-1)}}{2\times 2}

                       = \frac{4 +\sqrt{24}}{4}

                       = \frac{2+\sqrt{6} }{2}

x_{2} = \frac{-2-\sqrt{(-4)^{2}-4\times 2\times (-1)}}{2\times 2}

                        = \frac{4 +\sqrt{8}}{4}

                        = \frac{2-\sqrt{6} }{2}

These are the two roots of the equation.

Viviana had 4 and 1/5 pounds of sugar. She used 1/3 of the sugar she had. How much sugar did she use? Select all that apply
hram777 [196]

Answer:

11.339809 c

To convert a pound measurement to a cup measurement, multiply the sugar by the conversion ratio.

Since one pound of sugar is equal to 2.267962 cups, you can use this simple formula to convert:

cups = pounds × 2.267962

The sugar in cups is equal to the pounds multiplied by 2.267962.

For example, here's how to convert 5 pounds to cups using the formula above.

5 lb = (5 × 2.267962) = 11.339809 c

While experts usually suggest measuring dry ingredients by weight since it's more accurate, some recipes call for ingredients by volume and many of us don't have a scale when we need one. Because of the density of different types of sugar varies, it may not be obvious how to convert between a weight and volume measurements.

This table shows the approximate volume measurement for various weights of sugar, by type to help with the conversion.
