Answer:
The definition of a vector that you learn in linear algebra tells you everything you need to know about what a vector is in any setting. A vector is simply an element of a vector space, period. ... So, to say that a vector is a column of numbers, or a geometric object with magnitude and direction, is incorrect
Step-by-step explanation:
i hope this helps at all
So for QC to be a perpendicular bisector, it needs to make BC=CD lets label BC as X. BC+CD=BD. Because BC=CD, X+X=BD or 2X=24. Thus X=12. Thus BC=12. Now PB is a perpendicular bisector of AC so PB makes a right angle with AC at point B. PC=13(given) so because we have a right triangle, we can use the hypotenuse theorem so PC^2=BC^2+PB^2 or 13^2=12^2+PB^2 so 25=PB^2 so PB=5
Hope this helps!
