Answer:
2nd option
Step-by-step explanation:
To convert from (x, y ) → (r, θ )
where
r =
θ = ( )
Here (x, y ) = (- 4, 5 ), a point in the 2nd quadrant
r = = =
θ = ( ) ≈ 51.3° ← related acute angle , then
θ = 180° - 51.3° = 128.7°
Thus
(- 4, 5 ) → (, 128.7° ) in polar form
Answer:
Step-by-step explanation:
6 x 8 = 48
11,04 x 6 = 66,24
