two angles are complementary when the sum of them is equal to 90 degrees
Answer:
x = 0, π/4, π, 7π/4
Step-by-step explanation:
sin(2x) = √2 sin x
Use double angle formula.
2 sin x cos x = √2 sin x
Move everything to one side.
2 sin x cos x − √2 sin x = 0
Factor.
sin x (2 cos x − √2) = 0
Solve.
sin x = 0, cos x = ½√2
x = 0, π/4, π, 7π/4
There is 0.00105669 quarts in a milliliter
Answer:
(1,3)
Step-by-step explanation:
recall the vertex of a quadratic graph is simply the location where the graphs makes a u-turn.
in this case, the graph clearly makes a u-turn at x = 1 and y = 3
or the coordinates (1,3)
Answer:
Amelia
Step-by-step explanation:
lily made 85% of her shots
Amelia made 31 out of 36 of her shots
31/36 = 0.86
Amelia made 86% out of her shots
86% > 85%
