<span>The forces caused by these two ropes could be equally produced by a single rope pulling at 138.82 pounds at an angle of 21.42 degrees to the horizontal ground.
This can be found by considering each rope as the hypotenuse of a triangle. One leg of these triangles is the ground, and the other is perpendicular to the ground.
Using Sine and Cosine you can find the components of the force in the horizontal and vertical directions. These are then added to find the resultant force components.
The pythagorean theorem can then be used to find the net force of 138.82 pounds, and inverse tangent can be used to find the resultant angle of 21.42 degrees.
*These calculations were done to two significant digits. If more precision is desired you can repeat these calculations to the desired number of significant digits.</span>
The given function is even.
Solution:
<em>If f(-x) = f(x), then the function is even.</em>
<em>If f(-x) = -f(x), then the function is odd.</em>
Given function:
Substitute x = -x
= f(x) (given)
f(-x) = f(x)
From the definition, it is even.
Hence the given function is even.
Answer:
Option b (factor) is the correct choice.
Step-by-step explanation:
ANOVA would be used to assess whenever there were other statistically representative variations seen between results of two or even more individual (totally unconnected) categories.
<u>Two different kinds of independent variables exist such as:</u>
If the explanatory variables are such an effective variable otherwise we modify the argument of the variable to test its effect on something like a specific parameter.
Certain solutions don't apply to the specified scenario. So choice B was its perfect method for that.
