Answer:
12
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
(x - 9)² + (y - 4)² = 36 ← is in standard form
with r² = 36 ⇒ r = 
= 6
diameter = 2 × r = 2 × 6 = 12
Answer:
<em>y = </em>
<em> x + 1 </em>
Step-by-step explanation:
If AB ⊥ CD , then ( 
) ( 
) = - 1
y = - 
x + 3
y - ( - 4) = ( x - 7) ⇔ <em>y = </em><em> x + 1 </em>
The average would be the total amount divided by the 2 groups, so the answer would be 37.5 years old.
1488 labels divided by 16 labels equals 93. So the answer is D.
