10ft
Step-by-step explanation:
Answer: Points (-1 , 7.5), (0 , 6), and (1 , 4.5).
it is the third option because -3.2 is greater than -5.4
If you've learnt sin(A+B) = sinAcosB + cosAsinB,
sin(4u)
= sin(2u+2u)
= sin(2u)cos(2u) + cos(2u)sin(2u)
= 2 sin(2u) cos(2u).
I wouldn't classify it i would ignore it.
