Find <5uˉ,5vˉ+2wˉ><5 \bar{u}, 5 \bar{v}+2 \bar{w}>, given that <uˉ,vˉ>=4,<vˉ,wˉ>=−5<\bar{u}, \bar{v}>=4,<\bar{v}, \bar{w}>=-5, and <uˉ,wˉ>=−2<\bar{u}, \bar{w}>=-2 Number

Studdy Solution
Add the results from the previous step:
<5uˉ,5vˉ+2wˉ>=100+(−20)=80 <5 \bar{u}, 5 \bar{v} + 2 \bar{w}> = 100 + (-20) = 80
The value of the dot product is:
80 \boxed{80}
