Answer:
1/49
Step-by-step explanation:
1/7 to the 2nd power = (1/7)^2 = 1/7 • 1/7 = 1/49
Answer:
The percentage increase in salary of employee is 7.14 %
Step-by-step explanation:
Given as :
The initial pay of employee = $35,000 per year
The increase pay of employee = $37,500 per year
Let The percentage increase in salary = X %
So, X =
× 100
Or, X =
× 100
Or, X =
× 100
∴ X = 0.0714 × 100 = 7.14 %
Hence The percentage increase in salary of employee is 7.14 % Answer
Answer:
760.93 i think!
Step-by-step explanation:
7 x 100=700
6 x 10=60
9 x (1/10)=0.9
3 x (1/100)=0.03
700+60+0.9+0.03=760.93
3.) 3sinθ = sinθ - 1
3sinθ - sinθ = -1
2sinθ = -1
sinθ = -1/2
θ = sin^-1(-1/2) = π + π/6, 2π - π/6 = 7π/6, 11π/6
4.) tan^2 θ = -3/2 sec θ
sin^2 θ / cos^2 θ = -3/2(1/cos θ)
sin^2 θ / cos θ = -3/2
1 - cos^2 θ = -3/2 cos θ
cos^2 θ - 3/2 cos θ - 1 = 0
2cos^2 θ - 3cos θ - 2 = 0
2cos^2 θ - 4cos θ + cos θ - 2 = 0
2cos θ (cos θ - 2) + 1(cos θ - 2) = 0
(2cos θ + 1) = 0 or (cos θ - 2) = 0
cos θ = -1/2 or cos θ = 2 [but cos θ can never be 2]
θ = cos^-1(-1/2) = π - π/3, π + π/3 = 2π/3, 4π/3
