Answer:
D;
(x + 1/2)^2 + (y- √57)^2 = 81
Step-by-step explanation:
Mathematically, the general equation of a circle is given as;
(x-a)^2 + (y-b)^2 = r^2
where (a,b) represents the circle center and r represents the radius of the circle
Thus, we have this as follows;
(a,b) = (-1/2, √57) , r = 9
Substituting these values;
(x + 1/2)^2 + (y- √57)^2 = 9^2
The ratio of girls is 24.
If the total amount of swimmers is 40, you can divide it by 8 to get 5 multiples. If three of those 5's belong to the ratio of girls, the equation is 3 x 8. The answer is 24.
Hey there!
The equation we have been given is 5 - n/3 = -4.
Let's start by subtracting 5 from each side.
-n/3 = -9
Multiply each side by 3.
-n = -27
Multiply each side by -1.
n = 27
Check our answer.
5 - 27/3 = -4
5 - 9 = -4
-4 = -4
The value of n is 27.
Hope this helps!
