Give the equation of the circle centered at the origin and passing through the point (0,5)
Julli [10]

Answer:

x^{2} +y^{2}=25

Step-by-step explanation

The standard equation of a circle centered at origin is  x^{2} +y^{2} =r^{2}

r = radius of the circle

The circle is passing through the point (0,5)

∴ radius  r=\sqrt{(0-0)^{2}+(5-0)^{2} }

               r=\sqrt{0+25}

               r=\sqrt{25}

               r^{2}=25

∴ The equation of the circle is

     x^{2} +y^{2} = 25

What are my zeros (x^2 - 8x + 1)?
Pavel [41]

Answer:

x= 7.87298334621                          x=.12701665379

Step-by-step explanation:

This is in standard form so we have to factor this into

x^2-8x + 16 + 1 = 16

(x-4)^2 = 15

(x-4) = \sqrt{15\\}

x-4= ± 3.87298334621

x-4 = 3.87298334621                      x-4= -3.87298334621

x= 7.87298334621                          x=.12701665379
