Answer:

[-4, 3)

Step-by-step explanation:

We're talking about domain, which would be the least and greatest possible value x could be. In this graph, x is, at the least, -4. So we would use the bracket and write -4. The highest value x could be is 3, but if you look closely, the point is has an open circle, meaning we would use a parentheses for this side.

So, the answer is [-4, 3).

Hope this helps!!!

Find the center and radius of the circle whose equation is x 2 + y 2 + 10x − 1

Margaret [11]

we conclude that the center of the circle is the point (-5, 0).

<h3>How to find the center of the circle equation?</h3>

The equation of a circle with a center (a, b) and a radius R is given by:

$(x - a)^2 + (y - b)^2 = R^2$

Here we are given the equation:

$x^2 + y^2 + 10x - 1 = 0$

Completing squares, we get:

$x^2 + 10x + y^2 = 1$

Now we can add and subtract 25 to get:

$x^2 + 10x + 25 - 25 + y^2 = 1\\\\(x + 5)^2 -25 + y^2 = 1\\\\(x + 5)^2 + (y - 0)^2 = 26$

Comparing that with the general circle equation, we conclude that the center of the circle is the point (-5, 0).

What is 25% 136 so I know

tigry1 [53]

It's 34.

You can either intuitively know 25% means one-fourth and divide 136 by 4

Or

Convert the percentage to a decimal and multiply. 136 * 0.25 = 34
