Which shows the correct substitution of the values a, b, and c from the equation 0 = – 3x2 – 2x + 6 into the quadratic formula?

ZanzabumX [31]

Answer:

shows correct substitution of the values a, b, and c from the given quadratic equation into quadratic formula.

Step-by-step explanation:

Given: The quadratic equation

We have to show the correct substitution of the values a, b, and c from the given quadratic equation into quadratic formula.

The standard form of quadratic equation is then the solution of quadratic equation using quadratic formula is given as

Consider the given quadratic equation

Comparing with general quadratic equation, we have

a = -3 , b = -2 , c = 6

Substitute in quadratic formula, we get,

Simplify, we have,

Thus, and x_{2}=\frac{2-\sqrt{76} }{-6}

Simplify, we get,

Thus, shows correct substitution of the values a, b, and c from the given quadratic equation into quadratic formula.

The circumference of a circle whose radius is 9x sq. is

True [87]

<h3>The circumference of circle is $56.52x^2$ units</h3>

Solution:

Given that,

Radius of circle = $9x^2$ units

To find: circumference of circle

The circumference of circle is given as:

$C = 2 \pi r$

Where, r is the radius of circle

Substitute, r = $9x^2$

$C = 2 \times 3.14 \times (9x^2)\\\\C = 6.28 \times 9x^2\\\\C = 56.52x^2$

Thus circumference of circle is $56.52x^2$ units
