Answer:
= 250
Step-by-step explanation:
To obtain any term in the geometric sequence multiply the previous term by the common ratio r
here r = - 5 and 
= - 2, hence
= - 2 × - 5 = 10
= 10 × - 5 = - 50
= - 50 × - 5 = 250
You would multiply the growth rate (.009) by 2/3 to get the percent rate per year. Therefore, the answer is .006
I guess this is what you mean 3√a^10 and 3√b^7
The Shaded area is .25 of the circle, so:
Area/4 = Shaded
18/4 = Shaded
4.5 = Shaded
Hope this helps!
