Answer:
D
Step-by-step explanation:
The radius r is the distance from the centre to a point on the circle.
Calculate r using the distance formula
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 5, - 12)
r = 
= 
= 
= 
= 13 → D
you will have 8 tables so
72 chair / 8 tables = 9 chair per table

Answer:
-8.
Step-by-step explanation:
The difference quotient for ax^n = anx^(n-1) so here we have
Difference quotient of -8x + 1
= -8x(1-1) + 0 (the difference quotient of any constant is 0).
= -8x^0
= -8 * 1
= -8 (answer).
