The circle below is centered at the point (3, 1) and has a radius of length 2.
cluponka [151]

Answer:

$ x^2 + y^2 - 3x -y +6 = 0 $

Step-by-step explanation:

The equation of a circle with center $ (h,k) $ and radius $ r$ is given by

                 $ (x - h)^2 + (y - k)^2 = r^2 $

Here the center is: $ (3,1) $ and radius is $ 2 $.

Therefore, we have:

$ (x - 3)^2 + (y - 1)^2 = 2^2 $

$ \implies x^2 -3x +9 +y^2 -y +1 = 4 $

$ \implies x^2 + y^2 -3x -y +6 = 0 $

Given: y=3x-4. For what value of x does y equal zero?
DENIUS [597]
Value of x would be equal to 4/3

0 = 3x - 4
+4 +4

4 = 3 x {Divide each side by 3}

Which gives you the value of x = 4/3 or 1.33 if rounded

Find the radius of a circle if the circumference is 66cm​
FrozenT [24]

Answer:

Approximately 10.5, or 10.5095541.

Step-by-step explanation:

To find the radius given the circumference of a circle, we first have to divide the circumference by pi, or an estimation of 3.14. This will give us the diameter.

Since we know that the radius of a circle is simply half the diameter, we divide the number we got from the problem above by 2. This will give you your answer!

If M = 624,619,430,000 find the smallest power of 10 that will exceed M
AveGali [126]

<u>Answer-</u>

<em>The smallest power of 10 that will exceed M is 12.</em>

<u>Solution- </u>

Here,

M = 624,619,430,000

Writing this number in scientific notation,

M = 624,619,430,000 = 6.24619430\times 10^{11}

As the given number is the order of 11, so the next order will be greater than M.

So the next order of 10 will be,

=10^{11+1}

=10^{12}

Therefore, the smallest power of 10 that will exceed M is 12.
