What is the standard form of the equation of a circle whose diameter is 20 units and whose center is (−1,7)? Drag an expression or value to the boxes to correctly complete the equation.

The equation of the circle is

The standard form of the equation of a circle is:

From the question, we have:

So, the equation becomes

Substitute values for (a), (b) and (r)

Express 10^2 as 100

Hence, the equation of the circle is

Step-by-sep explanation:

Given:

Diameter of circle = 20 units

Center of circle = (-1, 7)

Standard form of the equation of a circle is expressed in the center-radius form as:

,

Where,

h = -1

k = 7

r = ½ of diameter = ½(20) = 10 units

Plug in the values into the equation

mean, 40.6

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
