Answer:
A
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 9, - 4) and r = ⇒ r² = (
)² = 5
(x + 9)² + (x + 4)² = 5 → A
Make a proportion using the ratio (A:B) given and number of As and Bs really gotten in the class ()
Cross multiply
2 * 40 = 5 * A
80 = 5A
Isolate A by dividing 5 to both sides
80/5 = 5A/5
16 = A
If 40 people in the class got B's then 16 people got A's
Hope this helped!
