Given:

A circle with its center at (0, -3).

To find:

The standard equation for the given circle.

Solution:

The standard form of a circle is , where (h, k) is the center of the circle and r is the radius of the circle.

The center of the given circle is at (0, -3).

We need to determine the radius of the circle. The center is at (0, -3) and a point with the same y coordinate is (3, -3).

The radius of the circle units.

So for the given circle, (h, k) is (0, -3) and r is 3 units.

So the equation becomes .

The standard equation for the circle is

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
