The difference of 2 squares is equivalent to
(their sum) times (their difference) .
Y² - 49 = (Y + 7) (Y - 7) .
The total displacement of the hiker's movement is 10 meters, East.
Firstly, displacement is a vector quantity that has both magnitude and direction.
Displacement is an object change in position. In other words it is a change in position of an object . Displacement can also be positive, negative or even zero.
According to the question the hiker walks 15 meters due north then 10 meters east, and finally 15 meters south.
Therefore, the total change in position or total displacement is 10 meters, East.

Answer:
4 and 10
Step-by-step explanation:
To solve this problem, we need to find all the numbers between 1 and 13 that have a sum of 14. The list is shown below:
1 + 13, 2 + 12, 3 + 11, 4 + 10, 5 + 9, 6 + 8, 7 + 7
Now we must figure out which set of numbers include one number that is 2/5 of the value of the other. We can do that by turning the sets of numbers into fractions as shown below:
(answer)
Answer:
x = 10.0
Step-by-step explanation:
Using the geometric mean formula:
x projection
----------------- = ---------------
entire base x
Here, the projection is 5 and the entire base is (20 + 5). So:
x 5
------------ = ------------
25 x
Cross multiply:
x² = 25 (5)
x² = 100
√x² = √100
x = 10
