What is the answer question

You might be interested in

What is the slope-intercept form of the equation of this line

makvit [3.9K]

$\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{9})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-2}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-2-9}{4-0}\implies \cfrac{-11}{4} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-9=-\cfrac{11}{4}(x-0) \\\\\\ y-9=-\cfrac{11}{4}x\implies y=-\cfrac{11}{4}x+9$

determine the equation of the parabola (simplified) with roots -3+sqrt6 and -3-sqrt6, and passing through the point (-1,4)

klio [65]

Given:

Roots:

$\begin{gathered} -3+\sqrt[]{6} \\ -3-\sqrt[]{6} \end{gathered}$

Point: (-1,4)

To determine the equation of the parabola with the given roots and point, we find the missing values first.

Since the roots are given, we can say that the equation is:

$y=a(x+3-\sqrt[]{6})(x+3+\sqrt[]{6})$

Next, we expand the terms.

$y=a(x^2+6x+3)$

Then, we plug in x= -1, and y=4 into the equation to get the value of a.

$\begin{gathered} y=a(x^2+6x+3) \\ 4=a((-1)^2+6(-1)+3) \\ \text{Simplify and rearrange} \\ 4=a(-2) \\ a=\frac{4}{-2} \\ a=-2 \end{gathered}$

So,

$undefined$

Integrate (x^3)/(a^2)-(x^2) ?

notka56 [123]

Hi!

$\frac{x^3}{(a^2)-(x^2)}$

<em>First remove parenthesis.</em>

$\frac{x^3}{a^2-x^2}$

<em>Factor $a^2-x^2$ or $(x+a)(a-x)$ </em>

$=\frac{x^3}{(a+x)(a-x)}$

Hope this helps! Thank you for posting your question at here on Brainly. Have a great day.
