Answer: Last option.

Step-by-step explanation:

The equation of a circle in Center-radius form is:

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

Where the center is at the point (h,k) and "r" is the radius.

If the center of this circle is at the origin, means that:

h=0\\k=0

Since the radius is 4, then:

r=4

Now we need to substitute these values into the equation of the circle.

(x-0)^2+(y-0)^2=(4)^2

Simplifying the equation, we get:

x^2+y^2=16

This matches with the last option.

Answer:

x²+y²=16

Step-by-step explanation:

the general equation for a circle is given as :

(x−h)²+(y−k)²=r²

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

in this case h=0, k=0 and r = 4

equation becomes

x²+y²=4²

or

x²+y²=16

Can someone please explain composite events to me in layman's terms?
kykrilka [37]

Step-by-step explanation:

A simple event is one that can only happen in one way - in other words, it has a single outcome. If we consider our previous example of tossing a coin: we get one outcome that is a head or a tail. A compound event is more complex than a simple event, as it involves the probability of more than one outcome.
