Answer:
3.6
Step-by-step explanation:
round ur previous answers to the nearest tenth then subtract them.
Step-by-step explanation:
2sin(x)cos(x) - sin(x) + 2cos(x)-1= 0
<=> sinx( 2cosx -1) + ( 2cosx -1) =0
<=> (sinx +1) + ( 2cosx-1)=0
<=> sinx=-1 or cosx= 1/2
+) sinx=1 => x= pi/2 + k×2pi
+)cosx=1/2 => x= pi/3+ k×2pi or x=-pi/3 + k×2pi
x€ [0,2pi] => x= pi/2, pi/3.
Answer:68x + 2

Answer:
19.29%
Step-by-step explanation:
Given
Population in 1990
= 254000000
Population in 2014
= 303000000
Increase = 303000000 - 254000000
= 49000000
% increase in population =
Increase /initial population x 100%
That’s
49000000/254000000 x 100%
0.1929 x 100%
19.29%
The population increased by 19.29%
