Question 1154025
<font color=black size=3>
PQ = 4i + 3j + 2k is in the form ai + bj + ck


The length of vector ai + bj + ck is sqrt(a^2 + b^2 + c^2), so


|PQ| = sqrt(4^2 + 3^2 + 2^2) = sqrt(16+9+4) = sqrt(29) = 5.38516


Exact Answer:  <font color=red size=4>sqrt(29)</font>

Approximate Answer: <font color=red size=4>5.38516</font>
