The answer is 10. Hope that helps
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
Answer:
Butter: 18/4 cups
Flour: 36 cups
Step-by-step explanation: I think this is right.
4 1/2 = 9/2
9/2 x 1/4 = 18/4 x 1/4 = 18/4
1 1/3 = 4/3
9/2 x 4/3 = 27/6 x 8/6 = 216/6 = 36
Answer:
y = 3/2x - 5
Step-by-step explanation:
y = 3/2x + b
1 = 3/2(4) + b
1 = 6 + b
-5 = b
Simplified would be: 3s + 2
