Answer:

See image

Step-by-step explanation:

When you reflect over a line, each point must be the same distance from the line of reflection (y = 1) but on the other side.

I hope this helps, let me know if you need further explanation :)

Find the distance between the points given (0, -6) and (9, 6)

Valentin [98]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{0}~,~\stackrel{y_1}{-6})\qquad (\stackrel{x_2}{9}~,~\stackrel{y_2}{6})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[9-0]^2+[6-(-6)]^2}\implies d=\sqrt{(9-0)^2+(6+6)^2} \\\\\\ d=\sqrt{9^2+12^2}\implies d=\sqrt{225}\implies d=15$

How much time wil it take a bug to travel 5 meters across the floor if it is traveling at 1 m/s?

ololo11 [35]

Answer:

5 seconds.

Step-by-step explanation:

Distance = Speed x Time.

So t = d/8

t = 5/1 = 1

So the bug will take 5s.

Celia is staring at the clock waiting for school to end so that she can go to track practice. She notices that the 4-inch-long m

sineoko [7]

Well, we know the minute hand is 4 inches long, thus, the radius of the circular clock is 4 then :)

part 1)

now, there are 360° in a circle.... the clock has 60 minutes, or 60 even intervals...now, how many degrees is it for each minute? well, let's divide 360° by 6 then, 360/6 is just 6. That means each minute to the next, is 6°, well, how many radians is that? well, we know there are π radians in 180°, so, how many radians in 6° then?

$\bf \begin{array}{ccllll}
radians&de grees\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\pi &180\\
x&6
\end{array}\implies \cfrac{\pi }{x}=\cfrac{180}{6}\implies \cfrac{\pi }{x}=30\implies \cfrac{\pi }{30}=x$

so, there are π/30 radians in 6°.

now, from 1:25 to 1:50 is 25 minutes, and thus 25 * π/30 radians, or 5π/6 radians.

part 2)

what is the arc made by those 25 minutes?

$\bf \textit{arc's length}\\\\
s=r\theta \qquad 
\begin{cases}
r=radius\\
\theta =\textit{angle in radians}\\
----------\\
r=4\\
\theta =\frac{5\pi }{6}
\end{cases}\implies s=4\cdot \cfrac{5\pi }{6}
\\\\\\
s=\cfrac{10\pi }{3}\implies s\approx 10.4719755\ inches$
