Help me with this problem please: Find the magnitude and direction of (a) 9B vector– 3Ā vector and (b) –5Ā vector + 8B vector, where Ā = (23.0, 59.0), B = (90.0, – 150.0).

(With the steps please)

45 is the correct answer

Inelastic is the answer your looking for.

How is it possible that phylogenies based on sequences from nuclear genomes and organellar genomes (i.e., chloroplasts and mitochondria) from the same group of species yield phylogenetic trees with different branching orders?   answer :   the genome of the endosymbiont is more closely related to members of the group in which it originally evolved, while the nuclear genome of the engulfing organism has its own evolutionary trajectory.
