What are the zeros of the quadratic function f(x) = 6x2 + 12x – 7?

Gnom [1K]

Answer:

A quadratic equation is of the form: $ax^2+bx+c= 0$ .....[1] where

a. b and c are coefficient and x is the variable.

The solutions of the equation are;

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

Given the function: $f(x) = 6x^2+12x-7$

To find the zero of this function.

Set f(x) = 0

⇒ $6x^2+12x-7=0$

On comparing this with equation [1] we have;

a = 6, b = 12 and c = -7

then;

$x = \frac{-12\pm\sqrt{(12)^2-4(6)(-7)}}{2(6)}$

$x = \frac{-12\pm\sqrt{144+168}}{12}$

or

$x = \frac{-12\pm\sqrt{312}}{12}$

or

$x = \frac{-12\pm 2\sqrt{78}}{12}$

$x = \frac{-6\pm \sqrt{78}}{6}$

Therefore, the zeros of the quadratic function f(x) are;

$\frac{-6+\sqrt{78}}{6}$ and $\frac{-6-\sqrt{78}}{6}$

If mBC = (9x-53) and mCD = (2x + 45) find mBAD

Rom4ik [11]

Answer:

$m\angle BAD=73^o$

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the value of x

Let

O ----> the center of the circle

we know that

Triangle BOC≅Triangle COD

$m\angle BOC=arc\ BC$ ----> by central angle

$m\angle COD=arc\ CD$ ----> by central angle

$m\angle BOC=m\angle COD$

therefore

$arc\ BC=arc\ CD$

substitute the given values

$(9x-53)^o=(2x+45)^o$

solve for x

$9x-2x=45+53\\7x=98\\x=14$

step 2

Find the measure of angle BAD

we know that

The inscribed angle is half that of the arc it comprises.

so

$m\angle BAD=\frac{1}{2} [arc\ BC+arc\ CD]$

$arc\ BC=9(14)-53=73^o$

$arc\ CD=2(14)+45=73^o$

substitute

$m\angle BAD=\frac{1}{2} [73^o+73^o]=73^o$

The amount of rhubarb in the original recipe is 3 1/2 cups. Using what you know of whole numbers and what you know of fractions,

Alexxx [7]

The easiest way, I think, is to convert the mixed number into an improper fraction, then multiply by 3.
3 1/2 = 7/2
7/2 · 3 = 21/2
now just change the improper fraction back to a mixed number by dividing and putting the remainder into fraction form
21/2 = 10 1/2

You could also multiply the whole number by 3 and the fraction by 3, ending up with 9 3/2, but then have to convert the improper fraction into a mixed number
3/2 = 1 1/2
then add the numbers together
9 + 1 1/2 = 10 1/2
either way works, whatever is easiest for you.
