Answer:
ratio of those who picked juice to milk
it refers to division
7000 more than 5500 by 7000-5500=1500
So the percent more=
×100
=
%
Simple interest:
Final value = principle (starting balance) x interest x time in years
Fv = PiN
18,000 x 0.045 x 3 = $2430
2430 + 18000 = $20430
Sin x - 1 = 0
sin x = 1
x 1 = π / 2
2 sin² x + 5 sin x + 2 = 0
Substitution: u = sin x
2 u² - 5 u + 2 = 0
2 u² - 4 u - u + 2 = 0
2 u ( u - 2 ) - ( u - 2 ) = 0
( u - 2 ) ( 2 u - 1 ) = 0
( sin x - 2 ) ( 2 sin x - 1 ) = 0
sin x - 2 = 0
sin x = 2 ( does not have solution )
2 sin x - 1 = 0
2 sin x = 1
sin x = 1/2
x 2 = π / 6 , x 3 = 5 π / 6
Answer:
x = π / 6 , π / 2 and 5 π / 6.
