Let's consider that 23.5 is 100% of rainfall.
23.5 ..... 100 %
21.2 ..... x %
Calculate x:
, which is around 90.2%.
The percent of decrease is 100 - 90.2 = 9.8 %.
Answer:
f(4)=-3
Step-by-step explanation:
f(1)=2
f(n)=f(n-1)^2-n
If n=2
f(2)=f(2-1)^2-2
f(2)=f(1)^2-2
f(2)=2^2-2
f(2)=4-2
f(2)=2
If n=3
f(3)=f(3-1)^2 - 3
f(3)=f(2)^2 - 3
f(3)=2^2-3
f(3)=4-3
f(3)=1
if n=4
f(4)=f(4-1)^2 - 4
f(4)=f(3)^2 - 4
f(4)=1^2 - 4
f(4)=1-4
f(4)=-3

Answer:
multiply 77 by 10 which is 770 then you multiply it by 5 which is half of 10 so 385 then add them together and you get 1155
<ABC would equal 106
seeing in triangle ABD angle A equals 67 you would multiply that by 2 and then subtract it from 180 to get 46, and then triangle DBC all the angles would equal 60. so then add 46 to 60 to get 106 the measure of <ABC
