Answer:
39364
Step-by-step explanation:
You can simplify the equation to make 4(1+3+9...) The nth term is therefore
so u can substitute that into the equation so 4(
..). This would simplify to 4(
+
). By simplifying this, you can make it so 4(
) = 4(4+36+324+2916+6561) =39364
Set up the equation
320 = 80c
When solved for c, That is how many chairs she can buy,
Then add 3, for the three free chairs she gets
The radius is 4 13/16 because half of 9 5/8 is 4 13/16.
Step-by-step explanation:
Use the distance formula:
d² = (x₂ − x₁)² + (y₂ − y₁)²
d² = (-3 − -12)² + (-8 − -11)²
d² = 9² + 3²
d² = 90
d = 3√10
