The equation of a circle is given below. Identify the center and radius. Then graph the circle.
Blizzard [7]

Answer:

  • Center = (3, 0)
  • Radius = 3
  • Graph = see below

Concept:

Here, we need to know the idea of the circle equation.

Circle equation: (x - h)² + (y - k)² = r²

(h, k) = center

r = radius

x = variable

y = variable

Solve:

<u>Given expression </u>

(x - 3)² + y² = 9

<u>Find the point of the center</u>

(h, k) = \boxed{(3,0)}

<u>Find the length of the radius</u>

r² = 9

\boxed{r=3}

Hope this helps!! :)

Is -100 rational or irational
pychu [463]

-100 is rational.

Just put 1 underneath -100 and you get \frac{-100}{1}

So that means it is rational since it can be a fraction!

<u>Answer:</u>

\boxed{\boxed{\pink{\bf \leadsto It \ will \ take \ 5 hours \ to \ travel \ 300 \ miles. }}}

<h3><u>Step-by-step explanation:</u></h3>

According to Question , a plane travels 120 miles in 2 hours. So here we will use unitary method .

\bf\implies If \ it \ covers \ 120 \ miles \ in \ 2 \ hours \\\\\bf\implies Then \ one \ mile \ will \ be \ covered \ in \ \dfrac{120}{2} hrs \\\\\bf\implies Hence \ 300 \ miles \ will \ be \ covered \ in \ \dfrac{2}{120}\times 300 hrs = \red{5 \ hours }

<h3><u>Hence</u><u> </u><u>it </u><u>will</u><u> </u><u>cover</u><u> </u><u>30</u><u>0</u><u> </u><u>miles</u><u> </u><u>in</u><u> </u><u>5</u><u> </u><u>hours</u><u> </u><u>.</u></h3>

Here it was a case of direct proportion in which if two things are directly proportional to each other. If one thing thing increases then the value of second also increases. Here if the time increases then the distance also increases
