Answer:
c. 63 toothpicks
Step-by-step explanation:
ok so the base for 16 would be 16 toothpicks
when i first see it that no matter what we would be multiplying 16 by 3 for that triangle shape
16 x 3 = 48
then we would have 15 for the connection toothpicks
48 + 15 = 63
16 would have 63 toothpicks
Remember: Standard formula
a x 10^b
The dot product of two vectors is defined as the sum of the multiplication of each of its components.
We have then:
B = [2 8 .6 3]
A = [3 0 2 -1]
Making the product point:
BA = [2 8 .6 3] [3 0 2 -1]
BA = (2 * 3) + (8 * 0) + (0.6 * 2) + (3 * (- 1))
BA = 4.2
Answer
BA = 4.2
