Answer:
See below
Step-by-step explanation:
cos (180 + x) = - cos x
sin (360 + x) = sin x
sin 360 - x) = -sin x
cos (180 - x) = - cos x
3cos (180° + x)sin (360° - X) = -3cos x (- sin x) = 3 cosx sinx
sin (360° + x)cos (180° - x) = sin x (- cos x) = -sinx cosx
3cos (180° + x)sin (360° - X)sin (360° + x)cos (180° - x)
= 3 cosx sinx (-sinx cosx) = -3 (sin x)^2 (cos x)^2
I am not sure what the question really is, but hopefully the above can steer you in the right direction.
Answer:
98 π R
Step-by-step explanation:
Surface area of sphere = 4 π R²
= 2 π R × 2 R
= 49 π × 2 R
= 98 π R
Each are divisible by 11 so the ratio equivalent would be 7:9
X - the number of plants in 8 in pots
y - the number of plants in 10 in pots
4 plants in 8 in pots and 2 in 10 in pots.
