Which equation represents circle C
options are in the picture

(x+4)^2 + (y-1)^2 = 162

Step-by-step explanation:

Equation of Circle : (x – h)^2 + (y – k)^2 = r^2

(h, k) is the center of the circle, r is the radius

The center is (-4, 1), plug it in to get:

(x+4)^2 + (y-1)^2 = r^2

To find the radius we can use the distance formula to find the distance between C and P:

Distance Formula: d =

Plug in C: (-4, 1) and P:(5, -8) to get

So, the equation is:

(x+4)^2 + (y-1)^2 =

(x+4)^2 + (y-1)^2 = 162

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
