Answer:
AB = 2
Step-by-step explanation:
Using the secant- secant theorem, that is
PA × PB = PD × PC , substitute values
10(10 + AB) = 8(8 + 7)
100 + 10AB = 8 × 15 = 120 ( subtract 100 from both sides )
10AB = 20 ( divide both sides by 10 )
AB = 2
Step-by-step explanation:
The angle between vectors is given by

The magnitudes for the vectors are as follows:




The dot product between the vectors is

Therefore, the angle between the two vectors is

or

The answer is B. Genetic Drift is events that change in a frequency of a gene variant (allele) in a population due to random sampling of organisms.
Answer:
You would count another table for the remainder. Therefore, 8 tables are needed to seat 63 people. It does not matter whether all seats are filled on the 8th table.
