Answer:
1.-12*(2r)^11 * (3s)
= -12*2048*3 r^11 s
= -73728 r^11 s
2.12C1 (2r)¹¹(-3s) = -36(2¹¹)r¹¹s = -73728r¹¹s
3.24 r - 36 s
The second term: -36 s
4.(2r-3s)^12
= (2r)^12 + 12C1 (2r)^11 (-3s)
= 2^12 r^12 + (12) 2^11 r^11 (-3) s
= 4096 r^12 - (12)(3)(2098) r^11 s
= 4096 r^12 - 73,728 r^11 s + .....
-73,728 r^11 s

Yan lang po alam ko at nahirapan ako e solved yan hehe pero hope it helps
Step-by-step explanation:
450 - 396 = 54
(54/450) * 100% = 12%
Hence the decrease is 12%.
Answer:
On the circle
Step-by-step explanation:
Centre: (0,0)
Radius = sqrt(45)
Distance of (6,-3) from the centre is
Sqrt(6² + 3²) = sqrt(45)
Since the distance is equal to the radius, it's on the circle
