Answer:
€75.80
Step-by-step explanation:
Start with €467.
End up with €88.
Total amount withdrawn:
€467 - €88 = €379
The total amount was withdrawn in 5 equal amounts.
Each amount taken is:
€379 ÷ 5 = €75.80
Answer:
60.6 cm
Step-by-step explanation:
The perimeter P is the sum of the 4 sides, that is
P = 14.8 + 12.5 + 16.3 + 17 = 60.6 cm
Answer:
7 1/2 square meters
Step-by-step explanation:
The area of a rectangle is the product of its length and width.
A = LW
A = (9 m)(5/6 m) = 45/6 m² = 7 1/2 m²
The area of Dina's new rug is 7 1/2 square meters.
Step-by-step explanation:
(2)
cos(2θ) tan θ + sin θ = 0
tan θ (cos(2θ) + cos θ) = 0
tan θ = 0
θ = kπ
cos(2θ) + cos θ = 0
cos(2θ) = -cos θ
cos(2θ) = cos(π − θ)
2θ = π − θ + 2kπ
3θ = (2k + 1) π
θ = (2k + 1) π / 3
Therefore, θ = kπ or (2k + 1) π / 3.
(3)
2 cos² θ − 2 cos²(2θ)
Power reduction formula:
1 + cos(2θ) − (1 + cos(4θ))
cos(2θ) − cos(4θ)
