Center will be (6,-4) and the radius will be square root of 7

Answer:

Center (6 , -4) and radius  √7.

Step-by-step explanation:

Given  : (x – 6)² + (y + 4)² = 7

To find  : Find the radius and center of the circle .

Solution : We have given that (x – 6)² + (y + 4)² = 7

We can write this equation as (x – 6)² + (y + 4)² = (√7)².

Standard form of circle (x – h)² + (y - k)² = (r)².

Where, (h , k) center coordinates , r  =radius .

On comparing with standard equation :

h = 6, k = -4 and r = √7.

Therefore, Center (6 , -4) and radius  √7.

What is g(x)?.......
8090 [49]

Answer:

g(x) = -|x|

Step-by-step explanation:

Are you familiar with the absolute value function y = |x|?

Its graph is v-shaped and opens up.

If the graph is turned upside down (so that it opens down), then g(x) = -|x|.

Unit rate<br>How many cents would you earn per minute? <br>Show work<br>ASAP
Yanka [14]
So, it depends. Imma give you two answers, all of which are the same at the end. They just have different ways to do it.

1. So, it's<span> $9 per hour, or $9 per 60 min </span>
<span>You can write a ratio: 9/60 = n/1 </span>
<span>In this case you have to divide 9 by 60 cause
60/60 = 1 </span>
<span>And n=0.15 </span>
<span>Answer: you earn 15 cents per min. 

2.</span><span>$9 = 900 cents </span>
<span>900 cents divided by 60 minutes = 15 cents in a minute.

Hope this helps love!! :)</span>

3. if you want to represent geologic time with a 24-hour clock, how many years would be represented by a single second, minute a
Amanda [17]

In geologic time scale a single second = 52,083.3 years, a minute = 3,125,000 years, an hour = 187.5 million years

Geologic time, the extensive interval of time occupied by the geologic history of Earth. Formal geologic time begins at the start of the Archean Eon (4.0 billion to 2.5 billion years ago) and continues to the present day.

So the geologic time scale (GTS) contains different ranks of times about Earth, obviously you know this already. However, the GTS has these different ranks in order from shortest length of time to longest length of time.

The Earth is about 4.5 billion years old. We want to convert this geological time in a period of 24 hours. So, if 24 hours correspond to 4.5 billion years, then, 1 Hour= 4.5 billion / 24=187.5 million years. There are 60 minutes in an hour ∴ 1 minute =187.5 million /60=3,125,000 years finally, one second has 60 seconds ∴ 1 second=3,125,000 / 60 = 52,083.3 year.

Given the diagram, a student wrote:
melomori [17]

What's wrong:

<W is congruent to <G not <F, and <V is congruent to <F not <G.

Statement:

<W is congruent to <G, and <V is congruent to <F because alternate interior angles are congruent. Therefore, Triangle WEV ~ Triangle FEG, by AA.
