Answer:
2520 patterns
Step-by-step explanation:
In 'n' 10! ways, books can be arranged. But, there are also 5! permutation of blue books 'n1', 2! permutation of identical green books 'n2', and 3! permutation identical black books 'n3'.
Therefore, for non identical arrangements:
= 2520
Therefore, the books can be arranged on a shelf in 2520 patterns
Answer:
The angle is .
Step-by-step explanation:
The building is 35 feet tall, and the rope is 400 feet long.Applying the trigonometric function, we have;
Sin θ =
The height of the building represents the opposite side, while the length of the rope represents the hypotenuse. Thus;
Sin θ =
Sin θ = 0.0875
θ = 0.0875
=
The angle made by the rope with respect to the ground is approximately .
