The center of a circle is at the origin. an endpoint of a diameter of the circle is at (-3, -4). how long is the diameter of the circle?

The length of the diameter of the circle is 10 unit.

Step-by-step explanation:

Given : The center of a circle is at the origin. An endpoint of a diameter of the circle is at (-3, -4).

To find : How long is the diameter of the circle?

Solution :

The center of a circle is at the origin i.e.

An endpoint of a diameter of the circle is at

The distance between the center and the end point of the diameter is the radius of the circle.

So, we find the radius with the help of distance formula,

Substitute the value in the formula,

Diameter is twice of radius

Therefore, The length of the diameter of the circle is 10 unit.

ik how do do this just give me a few minutes and i will give it to

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
