(2, 0°) is already in polar coordinates, with the smallest possible angle. The radius is 2, always 2. Expressions with variations of the angle are also good representations of (2, 0°) if their angles are all integer multiples of 360 degrees. For example: (2, 720°) represents the same point in polar coordinates as does (2, 0°).
Answer:
Width = 9 cm, length = 14 cm
Step-by-step explanation:
Width = w; Length = L
2(W+L) = 46, W+L = 23, W= 23-L
W*L = 126, (23-L)*L = 126
W = 9, L = 14
Answer:
A
Step-by-step explanation:
Note that
x² + 12x + 36 is a perfect square → (x + 6)², hence
= 
= (x + 6)
Hence
f(x) × g(x)
= (x + 6)(x³ - 11)
= 
- 11x + 6x³ - 66
= + 6x³ - 11x - 66 → A
Since 2 croissants = $3 we can work out that 1 croissant = $1.50
Multiply $1.50 by 31 and we get $46.50
Therefore 31 croissants is $46.50
A.Dose every point on the line
