Answer:
cosec =1/sin=5/4
sin=4/5
tan=4/3
cot=3/4
Step-by-step explanation:
Population t years after 2000 = 736,000 × 1.0149^t
736,000 × 1.0149^t = 1,000,000
1.0149^t = 1,000,000/736,000 = 125/92
Take log base 1.0149 of both sides
t ≈ 20.7
Population exceeds a million in 2021
(4, - 6 )
Under a counterclockwise rotation about the origin of 270°
a point (x, y ) → (y, - x ) , thus
(6, 4 ) → (4, - 6 )
Yes
90 minutes each - 360 ÷ 4
