sin(x) = ⁴/₅
sin⁻¹[sin(x)] = sin⁻¹(⁴/₅)
x ≈ 53.13
cos(90 - x) = cos(90)cos(x) + sin(90)sin(x)
cos(90 - 53.13) = cos(90)cos(53.13) + sin(90)sin(53.13)
cos(36.87) = 0cos(53.13) + sin(53.13)
cos(36.87) = sin(53.13)
cos(36.87) = cos(90 - 53.13)
cos(36.87) = cos(36.87)
The equation is:
y = 10 sin(π/15 t) + 30
where 30 represents the initial height of the blade above the ground and π/15 represents the period as we are given that the blade completes two rotation every minute.Finally the 10 represents the length of the blades.
Hope this helps :)
Answer: 64 cm ²
Step-by-step explanation:
The perimeter of this rectangle will be:
= 2 * Length + 2 * Width
= 2 * 10 + 2 * 6
= 20 + 12
= 32 cm
The square has the same perimeter. Squares have 4 equal sides so each side of the square must be:
= 32 / 4
= 8 cm
Area = Length * Width
= 8 * 8
= 64 cm ²
