Two feet is what percent of a yard? And please explain how I find the answer

GenaCL600 [577]

Percent means parts out of 100
x%=x/100

1 yard=3 feet
2 feet is what percent of 3 feet?
2=x% times 3
2=x/100 times 3
2=3x/100
multiply both sides by 100
200=3x
divide both sides by 3
66.6666666=x
answer is 66.66666%

What are the key features of a graph of a quadratic equation with only complex solutions

dybincka [34]

Answer:

If D< 0, the roots of the quadratic equation will b complex.

Step-by-step explanation:

Let $ax^{2} + bx + c =0$ is the given quadratic equation.

So, if the Discriminant (D) = $b^{2} - 4ac < 0$ , the the equation will have only complex solutions.

Complex roots are represented in the form of $(x \pm iy)$

1. <u> x represents the X axis (real) co ordinate,</u>

<u>y represents the Y axis (imaginary) coordinate</u>

<u />

<u />

2. Also, the graph of the with equation D < 0 NEVER CROSSES the X - axis, as there are no real roots of the equation, only complex roots.

3. Here. roots are always identical but are opposite in signs. Such pair or roots with opposite sign are called CONJUGATE PAIRS.
