You don't want 'x' in the polar form. The arguments
of the sin and cos should be angles.
You're doing great. You're already through the tough part.
You knew that x = r cos(α) and y = r sin(α) .
The correct equation for where you stopped is
x· y = r² · cos(α) · sin(α) = 1
You can simplify it a little if you remember the 'double-angle' equation:
sin(2α) = 2 · sin(α) · cos(α)
So cos(α) · sin(α) = (1/2) sin(2α)
and r² · cos(α) · sin(α) = 1
r² · sin(2α) = 2
Yess it must be you again perioddd girlll/guyyy
Answer:
1430
Step-by-step explanation:
1100×(0.05×6)+1100=1430
Elaborate? i will try to help!
Total marbles: 1+ 4+3 = 8
Picking a blue marble = 4/8 = 1/2
Picking a second one: 1/2 x 1/2 = 1/4 probability
