1 answer:
Fofino [41]3 years ago
5 0

Answer:

center= (0, -9)

r=1

Step-by-step explanation:

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

(h, k)= center

r= radius

We know that h is 0 since (x-h)^2 is x^2.

We know k= -9 from (y+9)^2

since r^2=1

r=1

Express the interval in set-builder notation and graph the interval on a number line<br> (-6.2]
zzz [600]

Answer:

{x|-6}

The number line is attached.

Step-by-step explanation:

By definition Set-builder notation is a mathematical shorthand used to provide specific details about a set.

In this case, you have the following interval:

(-6,2]

You can obsseve that the left hand contains a parentheses, which means that -6 it is not included, then:

-6

The right hand contains a bracket, which means that 2 is included:

\leq 2

The inequality is:

-6

Therefore, in Set-builder notation this is:

{x|-6}

Observe the number line attached. Since -6 is not included, you must use an unfilled circle. Since 2 is included, you must use a filled circle.
