Question

Find the dot product. (1.3, -3.5).(-4.3, 2) =

Answer 1

To find the dot product, multiply the corresponding components of the vectors and sum them up.

Step-by-step explanation:

To find the dot product of two vectors, you multiply the corresponding components of the vectors and sum them up. For example, the dot product of (1.3, -3.5) and (-4.3, 2) is:

(1.3)(-4.3) + (-3.5)(2) = -5.59 - 7 = -12.59

So, the dot product is -12.59.

Answer 2

The dot product of (1.3, -3.5) and (-4.3, 2) is -12.59

Finding The Dot Product Of The Vectors.

The dot product of two vectors (a, b) and (c,d) is given by:

a · c + b · d

(1.3, −3.5) ⋅ (−4.3, 2)

= (1.3 ⋅ − 4.3) + ( −3.5 ⋅ 2)

= -5.59 - 7

= -12.59

Therefore, the dot product of (1.3, -3.5) and (-4.3, 2) is -12.59
