Answer:
sin a = -3/5
Step-by-step explanation:
sin^2(a)+cos^2(a)=1
sin^2(a)+ (4/5)^2 = 1
sin^2(a) = 1 - 16/25 = 9/25
sin a = 3/5 ( in Quadrant 1)
In quadrat IV the sine is negative
so sin a = -3/5
Answer:
percent increase=135%
Step-by-step explanation:
if population is increased from 14,523 to 16,489, then we get the increase of 16489-14523=1966
to find the percent increase, we need to use the following formula of percent increase
%
actual increase=1966
original amount=14523
so percent increase is found as
%
percent increase=0.1353x100%
percent increase= 135.3%
to round to the nearest percent we get
percent increase=135%
