Answer:
v . w= -13
Step-by-step explanation:
Evaluate the expression: v ⋅ w Given the vectors: r = <8, 1, -6>; v = <6, 7, -3>; w = <-7, 5, 2>
Solution
Given the vectors:
r = <8, 1, -6>
v = <6, 7, -3>
w = <-7, 5, 2>
If you're asking about the dot product.
The dot product is a scalar. It is the sum of the product of the corresponding components.
v.w = (6*-7) + (7*5) + (-3*2)
= -42+35-6
= -13.
Answer:
1 1/2

Answer:
He can run 20 ft in 15 seconds
Step-by-step explanation:
we need to change yards to ft
3ft = 1yd
100 yds * 3ft/1yd = 300 ft
distance = rate * time
300 ft = rate * 15 seconds
divide by 15 seconds on both sides
300 ft/15 seconds = rate
20 ft/sec
He can run 20 ft in 15 seconds
