Step-by-step explanation:

when B is a subset of C, it means that everything in B is also contained in C. C just contains more than that.

when A is a subset of B, it means in the same way that everything in A is also contained in B. since it is contained in B, it is also contained in C.

so, A is therefore also a subset of C.

Learning goal: to understand the rules for computing dot products. let vectors a=(2,1,−4), b=(−3,0,1), and c=(−1,−1,2). part a -
miv72 [106K]
For this case we have the following vectors:
 a = (2,1, -4)&#10;&#10;b = (- 3,0,1)&#10;&#10;c = (- 1, -1,2)
 The dot product of two vectors is a scalar.
 The point product consists of multiplying component by component and then adding the result of the multiplication of each component.
 For the product point of the vectors a and b we have:
 a.b = (2,1, -4). (- 3,0,1)&#10;&#10;a.b = (2) (- 3) + (1) (0) + (-4) (1)&#10;&#10;a.b = - 6 + 0 - 4&#10;&#10;a.b = - 10
 Answer:
 
The product point of the vectors a and b is: 
 
a.b = - 10

Take the horse to overtake the
S_A_V [24]

Answer:

  • 120 km/h

Step-by-step explanation:

  • Speed in one direction = 40 km/h
  • Speed on return = x
  • Average speed = 60 km/h

Let the distance be d

<u>Average speed </u>

  • 2d/(d/40 + d/x) = 60
  • d/40 + d/x = 2d/60
  • 1/40 + 1/x = 1/30
  • 1/x = 1/30 - 1/40
  • 1/x = (4-3)/120
  • 1/x = 1/120
  • x = 120 km/h
