What is the standard form of the equation of a circle whose diameter is 20 units and whose center is (−1,7)?

VARVARA [1.3K]

Answer:

$(x + 1)^2 + (y - 7)^2 = 100$

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:

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

Where,

h = -1

k = 7

r = ½ of diameter = ½(20) = 10 units

Plug in the values into the equation

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

$(x - (-1))^2 + (y - 7)^2 = 10^2$

$(x + 1)^2 + (y - 7)^2 = 100$

Kayla and two of her friends form an investment club. Each contributes $250 to an account that earns 5% interest, compounded ann

vaieri [72.5K]

The multiplier of each account's value is 1.05³ = 1.157625.

The $750 in the club's account will grow to
$750×1.157625 = 868.22
and each member will get 1/3 of that amount, $289.

The $250 in Sheri's individual account will grow to
$250×1.157625 = $289.

Sheri, Kayla, and Kayla's two friends will all have the same amount as a result of their investments.
