Answer:
x(2,3), y(2,5) z(7,3)
Step-by-step explanation:
Answer:
[B] 0, 19.5, 160.5, 180, 360
Step-by-step explanation:
3 sin²θ = sin θ
3 sin²θ − sin θ = 0
sin θ (3 sin θ − 1) = 0
sin θ = 0 or sin θ = ⅓
If sin θ = 0, θ = 0°, 180°, 360°.
If sin θ = ⅓, θ = 19.5°, 160.5°.
Answer:
The common difference (or common ratio) = 0.75
Step-by-step explanation:
i) let the first term be = 80
ii) let the second term be = . r = 80 × r = 60 ∴ r = = 0.75
iii) let the third term be = . r = 60 × r = 45 ∴ r = = 0.75
iv) let the fourth term be = . r = 45 × r = 33.75 ∴ r = = 0.75
Therefore we can see that the series of numbers are part of a geometric progression and the first term is 80 and the common ratio = 0.75.
25km east + 25km return+ 40km west + 40km return = 130km
