Answer:

The distance is 5.8x10^7 km

The diameter is 2.5x10^-3 cm

and before a comparison is made both numbers have to be written in the same unit. meaning the km has to be converted to cm or vice versa.

the point 3,2 lies on a circle.what is the exact length of the radius of this circle if the center is located at (-1,-4)
Crazy boy [7]
You can use the distance formula to solve this.

Distance Formula:
d = \sqrt{(X_2 -X_1)^2 + (Y_2 - Y_1)^2}

I am going to use point (3,2) as point 1 and (-1,-4) as point 2
Insert the points into the formula
d = \sqrt{(X_2 -X_1)^2 + (Y_2 - Y_1)^2}
d = \sqrt{((-1) - 3)^2 + ((-4) - 2)^2}
Solve:
d = \sqrt{((-1) - 3)^2 + ((-4) - 2)^2}
d = \sqrt{(-4)^2 + (-6)^2}
d = \sqrt{16 + 36}
d = \sqrt{52}
d = \sqrt{52} = \sqrt{4}\sqrt{13}
d = \sqrt{52} = 2 \sqrt{13}
d = 2 \sqrt{13}
radius = 2 \sqrt{13} = 7.2111

Write the following equation in the general form ax by c = 0. y - x - 1 = 0
Elena-2011 [213]

If you would like to write y - x - 1 = 0 in the general form, you can do this using the following steps:

The general form of the equation is: ax + by + c = 0.

y - x - 1 = 0

-x - y - 1 = 0


The correct result would be <span>-x - y - 1 = 0</span>.
