Answer:

Rate of change of length of shadow is $\frac{15}{7} ft/s$

Step-by-step explanation:

Consider the figure

We have

$\begin{aligned}&\frac{d x}{d t}=\text { rate of person walking } \\&\frac{d y}{d t}=\text { rate of change of shadow length } \\&\frac{d x}{d t}+\frac{d y}{d t}=\text { rate of change of tip of shadow }\end{aligned}$

$\begin{aligned}&\frac{6}{20}=\frac{y}{x+y} \\&6(x+y)=20 y \\&6 x+6 y=20 y \\&6 x=14 y\end{aligned}$

$6\left(\frac{d x}{d t}\right)=14\left(\frac{d y}{d t}\right)\\\\6(5)=14\left(\frac{d y}{d t}\right)\\\\\frac{30}{14}=\frac{d y}{d t}\\\\\frac{15}{7}=\frac{d y}{d t}\\\\$

Rate of change of length of shadow is $\frac{15}{7} ft/s$

Answer:

$B) \sqrt{2}$ ÷ $2\sqrt{5}$

Step-by-step explanation:

$A$ → $2\sqrt{5}$ ÷ $\sqrt{5}$

$= \frac{2\sqrt{5} }{\sqrt{5} }$

<u>→ </u><u>2</u><u> is a rational number</u>

$B)$ → $\sqrt{2}$ ÷ $2\sqrt{5}$

$=\frac{\sqrt{2} }{2\sqrt{5} }$

$=\frac{\sqrt{2} }{\sqrt{2}*\sqrt{2}*\sqrt{5} }$

$= \frac{1}{\sqrt{10} }$

<u>↑ is irrational number</u>

$C)$ $\frac{\pi }{2}$ ÷ $\pi$

$= \frac{\pi }{2} *\frac{1}{\pi }$

$=\frac{1}{2}$

<u>↑ is a rational number</u>

$D)$ $5\pi$ ÷ $\pi$

$= 5$

<u>↑ is a rational number</u>

<u>So,</u><u> Option B</u><u> is your answer</u>

hope it helps..
