Answer: 4n-7
Step-by-step explanation:
Answer: x = -8, y = 13
Step-by-step explanation:
x+y=5
3x+y=-11
now subtract the two equations
x-3x+y-y=5-(-11)
-2x=16, x = -8
now substitute
-8 + y = 5, y = 13
D. divide them by 25 and there it is
The formula of interest is
A = (1/2)r²·θ
You have r = 9 m, θ = 3π/5. Then the area is
A = (1/2)(9 m)²(3π/5) = 24.3π m²
The sector area is ...
A ≈ 76.3 m²
