In words, the scalar product of two vectors can be thought of as the product of the magnitude of ~a with the magnitude of the pr

ojection of ~b onto the direction of ~a. It is used to calculate the product of vector quantities when only the parallel components of each vector contribute (e.g., Work = Force • Displacement). Let ~a = h9, 6.75, 0i and ~b = h2.97, 6.075, 0i. Calculate ~a • ~b.

Answer:

  67.73625

Step-by-step explanation:

The dot (scalar) product is also the sum of products of corresponding vector components.

~a • ~b = 9·2.97 +6.75·6.075 +0·0 = 27.73 +41.00625 = 67.73625

Answer:

Answer B:  10.12

Step-by-step explanation:

Let the numbers be represented by a, b and c.  Their sum is 44.84.  The number a is 24.6.  Further, assume that b = c.

Then 24.6 + b + b = 44.84.

Let's isolate 2b:

Subtract 24.6 from both sides of this equation, obtaining:

2b = 20.24.

Finally, divide both sides of this equation by 2.  We get b = 10.12.

This corresponds with Answer B.

Do you have 1 7/8 divided by one half. With dividing you multiply by the reciprocal of 1/2 which is 2/1. Before you do that change 1 7/8 into a mixed number which is 15/8. 15 x 2= 30, 8 x 1=8. New fraction is 30/8. Now as a mixed number it is 3 6/8 which simplifies to 3 3/4. So your answer is D
