Answer:
The value of function at x = 2 is 8.
Step-by-step explanation:
Given : Function 
We have to find the value of given function at x = 2 , that is f(2)
Consider the given function
To find the value f(2) put x = 2 in given function ,
We have,
Simplify, we have,
Simplify further, we have,
Thus, the value of function at x = 2 is 8.
6(-3)=-18, |-5|=5, and |3|=3
so that the answer of this equation is: -18-5+3=-20
The roof will be in the shape of an isosceles triangle with a base length of 30 m and two sides that are 17 m. The two 17 m beams will have the same angle of elevation since they have to might in the middle.
So to find the angle of elevation, we can split the roof in half vertically to create a right triangle. The base will now be 15 m, and the hypotenuse will be 17. Now we can use a trigonometry function to solve for the angle. We know the hypotenuse and the side adjacent to the angle, so we can use cosine.
The answer is 28.1 degrees
