The ratio 9/15 and 6/15 form a proportion
6t^-7 * 3t^5 = 1/6t^7 * 3t^5
Answer:
This is a radioactive decay / half-life problem.
Initial amount of C 14 = 100% Present Amount = 57%
k = .0001 (that value should be negative)
Nt = No * e^ (k*t)
You need to solve that equation for "time" (equation attached)
time = natural log (Ending amount / Starting Amount) / k
time = natural log (57% / 100%) / -.0001
time = ln (.57) / -.0001
time = -.56211891815 / -.0001
time = 5,621.2 years (age of the bird skeleton)
These problems are quite complicated but I think I know this pretty well.

Step-by-step explanation:
I’m pretty sure it’s D, if you count your boxes from the origin you go up four and over one so it would be 4x for slope
Answer:
45
Step-by-step explanation:
A whole circle is 360 so if you divided that by 8 you get 45
