9x² - 12x + 4 <br><br>pls need ans.

kolezko [41]

Step-by-step explanation:

$\tt{9 {x}^{2} - 12x + 4}$

Here, the second order of polynomial ax² + bx + c is factorized and expressed as the product of two linear factors. First, we have to find the two numbers that adds to 12 and if we multiply those numbers , we get 36 ( The two numbers should be 6 and 6 ).

⟶ $\tt{9 {x}^{2} - (6 + 6)x + 4}$

⟶ $\tt{9 {x}^{2} - 6x - 6x + 4}$ { Distribute x through the parentheses )

⟶ $\tt{ \underbrace{9 {x}^{2} - 6x}} \: - \underbrace{6x + 4}$

⟶ $\tt{3x(3x - 2) - 2(3x - 2)}$

⟶ $\tt{(3x - 2)(3x - 2)}$

⟶ $\tt{ {(3x - 2)}^{2} }$

$\pink{ \boxed{ \boxed{ \tt{ Our \: final \: answer : \boxed{ \underline{ \tt{{(3x - 2)}^{2} }}}}}}}$

The end of a pendulum with a length of 21 cm travels an arc length of 24 cm. How many degrees does the pendulum swing?

Tanya [424]

It is given in the question that the end of a pendulum with a length of 21 cm travels an arc length of 24 cm.

So here radius is 21 cm and the arc length is 24 cm .

Now we use the arc length formula , which is

$s = r* \theta$

Where s is the arc length and r is the radius.

Substituting these values, we will get

$24 = 21 \theta
\\
\theta = \frac{24}{21}
\\
\theta = 1.143 radians$

And now we need to convert radian to degree, and for that we have to multiply by $\frac{180}{ \pi}$

That is

$1.143 * \frac{180}{ \pi} =65.48 degree$
