The general equation for a circle is:

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

Where the center is (h,k) and the radius is r.

The equation we are given is:

(x-2)^2+(y+3)^2=80

From this, the center is (2,-3), and the radius is \sqrt{80}, or 4\sqrt{5}.

Let me know if you have any questions, thanks!

Please help! I really don't understand!

A. yes this is a statistical question. it is a statistical question because you can answer the question by collecting data.


b. some clusters are.. 3,4,5, and 6 they are clusters because they are assembled around a particular value. the peak is 6 because it is the highest number it reaches. there are no gaps in this table.



c. to calculate the average with a graph you sum the numbers then divide by the total number of values in the set. for this table you add 1+2+3+3+4+4+4+5+5+5+5+5+5 then you divide by 15.

1+2+3+3+4+4+4+5+5+5+5+5+5=51

51 ÷ 15= 3.4

suppose someone tells you that she has a triangle with sides having lengths 2.6, 8.1 and 8.6 is this a right triangle? why or wh
yawa3891 [41]
By the converse of the Pythagorean Theorem, if 8.6 ^2 = 8.1 ^2 + 2.6 ^2 , then the triangle is right. 73.96 is not equal to 72.37 so the triangle is not a right triangle.

8.6^2 is greater than (8.1^2 + 2.6^2) which means that the triangle is obtuse.
The obtuse angle is opposite the 8.6 side.

Dan spends 2 5 of his wages on rent and 1 2 on food. If he makes ?430 per week, how much money does he have left?
BartSMP [9]

Answer:

Dan would be left over with $43 a week.

Step-by-step explanation:

\frac{2}{5} = 40%

\frac{1}{2} = 50%

Rent: $430 - 40% = $172

Food: $430 - 50% = $215

$215 + $172 = $387

$430 - $387 = $43
