Answer:
A- a regular hexagon
Step-by-step explanation:
Answer:
I only know the first one...
C) 4896
Step-by-step explanation:
For the first pick, 18 students to pick from then 17 left and then 16 left.
18 * 17 * 16 = 4896
The dot product is used to determine the magnitude of the resultant vector of two component vectors. It is expressed as a·b. It does not literally mean that you multiply their values. Instead, you multiply their matrices. However, since we cannot find matrices, let's just find the resultant vector through theorems involving triangles. By cosine law:
R = √[a² + b² - 2abcos(3π/4)]
R = √[60² + 30² - 2*60*30*cos(3π/4)]
R = 83.94
Thus, a·b = 83.94
