Step-by-step explanation:
It is convenient to let a spreadsheet or calculator do the tedious sum of products. Term C22 will be B21·A12 +B22·A22 = 0.6·0 +3·(-1) = -3, for example. Other terms are similarly computed. In general Crc will be the sum of Brx·Axc, where x = 1 or 2.
Using the Pythagorean theorem we can find the distance from the swimming pool to the courthouse:
Swimming pool to courthouse:
Distance = √(3^2 + 4^2)
Distance = √(9+16)
Distance = √25
Distance = 5 kilometers
Now total the distance the bird flew:
Courthouse to Library is given as 3 kilometers.
Library to swimming pool is given as 4 kilometers
Swimming pool to courthouse we calculated as 5 kilometers.
Total distance = 3 + 4 + 5 = 12 kilometers.
