Its something like this. Your line should be straight. My line isn't straight because I didn't space the numbers correctly.
Answer:
With the rule: d(n) = d(n-1) x (-5), we have:
d(1) = 8
d(2) = d(1)x(-5) = 8x(-5) =-40
d(3) =d(2)x(-5) = -40x-5 =200
Other way:
d(n) = d(n-1) x (-5) => d(n) = d(1)x(-5)^(n-1)
d(3) = d(1)x5^(3-1) =8x5^2=8x25 =200
Answer: C^2(1+c) I hope this helps
I believe this is J with a radius of 6
the formula for circumference is 2(pi)r so i just took the 12(pi) and divided it by 2, which left me with 6(pi), meaning that 6 would be the "r" in the situation
