What is the general equation of a circle centered at the origin?

It is x2+y2−169=0.

Explanation:

The circle you are looking fore is composed by all the points with a distance from the origin of 13/ The distance of a point from the center is

d=√x2+y2 and this distance has to be 13, so

13=√x2+y2 and to obtain the equation we can do the square

132=x2+y2 and the final equation is

x2+y2−169=0.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
