Answer:

$\boxed{ \bold{ \boxed{ \sf{ {x}^{4} + 3 {x}^{3} - 9 {x}^{2} - 12x + 20}}}}$

Step-by-step explanation:

$\sf{( {x}^{2} - 4)( {x}^{2} + 3x - 5)}$

Use distributive property

$\dashrightarrow{ \sf{ {x}^{2} ( {x}^{2} + 3x - 5) - 4( {x}^{2} + 3x - 5)}}$

$\dashrightarrow{ \sf{ {x}^{4} + 3 {x}^{3} - 5 {x}^{2} - 4 {x}^{2} - 12x + 20}}$

Collect like terms

$\dashrightarrow{ \sf{ {x}^{4} +3 {x}^{3} - 9 {x}^{2} - 12x + 20}}$

Hope I helped!

Best regards! :D

How do I find the distance between (-2,5) and (22,12)

jok3333 [9.3K]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-2}~,~\stackrel{y_1}{5})\qquad (\stackrel{x_2}{22}~,~\stackrel{y_2}{12})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[22-(-2)]^2+[12-5]^2}\implies d=\sqrt{(22+2)^2+(12-5)^2} \\\\\\ d=\sqrt{24^2+7^2}\implies d=\sqrt{625}\implies d=25$

Which single transformation can be applied to the graph of y = 72 <img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D" id="TexFormu

Allisa [31]

Answer:

B. Vertical Compression

Step-by-step explanation:

<em>You've answered the question; However, I'll assist with the explanation;</em>

Given

Original: $y = 72\sqrt x$

Translated: $y = 9\sqrt x$

Required

Determine the type of transformation applied to the original function

Observing both functions, we notice that $\sqrt x$ is a common factor;

This implies that the function was compressed or stretched along the y axis (vertically)

To determine if its vertical compression or stretch;

We have to divide the translated function by the original function;

$Ratio = \frac{9\sqrt x}{72\sqrt x}$

$Ratio = \frac{9}{72}$

$Ratio = 0.125$

<em>Because 0.125 < 1, then the transformation is a vertical compression</em>
