Nancy and Harry are sliding a stone statue and moving it to a new location in their garden. Nancy is pushing the statue with a f

Nimfa-mama [501]

Answer:

197,8879 N.

Step-by-step explanation:

The magnitude of the horizontal force exerted on the statue can be calculated using trigonometric functions.

The question given says that Nancy is pushing the statue with a force of 120 N at a 60° angle to the horizontal and Harry is pulling the statue with a force of 180 N at a 40° angle with the horizontal.

With that information can be calculated the horizontal force exerted on the statue by Nancy, the horizontal force exerted on the statue by Harry and, adding that results, the total horizontal magnitude can be calculated.

The cosine function can be used to calculate the horizontal component of the forces exerted by Nancy and Harry, to determine the horizontal component of the force exerted on the statue.

F= (120 N cos 60°) + (180 N x cos 40°)

F= 197,8879 N

What value of n makes the statement true? 6xn · 4x2 = 24x6

tensa zangetsu [6.8K]

The answer is: $n=4$

The explanation of this exercise is shown below:

1. You have the following expression given in the problem above:

$(6x^{n})(4x^{2})=24x^{6}$

2. By the exponents properties, when you multiply powers with the same base, you must sum the exponents. In this case the base is $x$ , therefore, you must sum the exponents.
