Answer:

r=9

Step-by-step explanation:

6       2

---- = ------

r         3

We can use cross products to solve

6 * 3 = 2 * r

18 = 2r

Divide by 2

18/2 = 2r/2

9 = r

\bf{Hey\ there!}

\bold{\frac{6}{r}=\frac{2}{3}}

\text{First, you have to cross multiply}

\bullet{\ \bold{numerator\times denminator}}

\bullet{ \ \bold{denominator\times numerator}}

\bold{6\times3=18}

\bold{2\times r=2r}

\text{Your equation becomes: 2r = 18}

\text{\underline{DIVIDE}\ by 2 on each of your sides!}

\bold{\frac{2r}{2}=\frac{18}{2}}

\bf{Cancel:\frac{2r}{2}\ because\ it\ gives\ us the result\ of\ 1}

\bf{Keep:\frac{18}{2}\ because\ it\ gives\ us the\ value\ of\ r}

\bf{18\div2=9}

\boxed{\boxed{\bold{Answer:x=9}}} \checkmark

\text{Good luck on your assignment and enjoy your day!}

earnstyle [38]

Answer:

1. (x,y)→(y,-x)

2. (x,y)→(-y,x)

3. (x,y)→(-x,-y)

Step-by-step explanation:

1. Rotation 90° clockwise (or 270° counterclockwise) about the origin changes x into y and y into -x, so it has the rule

(x,y)→(y,-x)

2.  Rotation 90° counterclockwise (or 270° clockwise) about the origin changes x into -y and y into x, so it has the rule

(x,y)→(-y,x)

3.  Rotation 180° clockwise  about the origin changes x into y and y into -x, so it has the rule

(x,y)→(-x,-y)

Here you can apply rotation by 90° clockwise twice, so

(x,y)→(-y,x)→(-x,-y)

How do you turn 12/15 and 68/80 into a decimal and into a percent
Allisa [31]
\frac{12}{15}\\\\divide\ a\ numerator\ and\ a\ denominator\ by\ 3\\\\12:3=4;\ 15:3=5\\\\therefore\ \frac{12}{15}=\frac{4}{5}\\\\multiply\ a\ numerator\ and\ a\ denominator\ by\ 2\\\\4\cdot\ 2=8;\ 5\cdot2=10\\\\therefore\ \frac{12}{15}=\frac{4}{5}=\frac{8}{10}=\boxed{0.8}\Rightarrow0.8\cdot100\%=\boxed{80\%}



\frac{68}{80}\\\\divide\ a\ numerator\ and\ a\ denominator\ by\ 4\\\\68:4=17;\ 80:4=20\\\\therefore\ \frac{68}{80}=\frac{17}{20}\\\\multiply\ a\ numerator\ and\ a\ denominator\ by\ 5\\\\17\cdot\ 5=85;\ 20\cdot5=100\\\\therefore\ \frac{68}{80}=\frac{17}{20}=\frac{85}{100}=\boxed{0.85}\Rightarrow0.85\cdot100\%=\boxed{85\%}

A parabola and a circle are graphed into the standard (x,y) coordinate plane. The circle has a radius of 4 and is centered at (1
Gala2k [10]

Answer:

Correct answer: Two point of intersection and one touch point.

Step-by-step explanation:

Cartesian form of parabola is: y= a(x-1)² + 5  and point named A(2,4)

when we replace the coordinates of the point A in the formula we get

a = - 1 and parabola is  y= - (x-1)² + 5 which means that it faces the opening downwards. The parabola touches the circle in vertex.
