Answer:
The magnitude of the vector A is <u>51 m.</u>
Explanation:
Given:
The horizontal component of a vector A is given as:
The vertical component of a vector A is given as:
Now, we know that, a vector A can be resolved into two mutually perpendicular components; one along the x axis and the other along the y axis. The magnitude of the vector A can be written as the square root of the sum of the squares of each component.
Therefore, the magnitude of vector A is given as:
Now, plug in 44.4 for , 25.1 for and solve for the magnitude of A. This gives,
Therefore, the magnitude of the vector A is 51 m.
Using the formula for permutation, there are 5040 ways that 7 objects are taken 1 at a time.
<h3>What is permutation?</h3>
The permutation of objects refers to the number of ways that an object can be selected from a number of objects.
Given that;
nPr = n!/(n - r)!
Hence;
7P1 = 7!/(7 - 1)!
7P1 = 7 * 6 !/6!
7P1 = 7 * 6 * 5 * 4 * 3 * 2 *1
7P1 = 5040
