Answer:
Therefore the given vectors are orthogonal for b = 0,±3.
Step-by-step explanation:
If and are two vectors orthogonal, then the dot product of and will be zero.
i.e
If and
Given two vectors are (-18,b,9) and (b,b²,b)
Let
and
Therefore,
=(-18).b+b.b²+9.b
= -18b+b³+9b
= b³-9b
Since and are orthogonal. Then = 0.
Therefore,
b³-9b= 0
⇒b(b²-9)=0
⇒b =0 or b²=9
⇒b=0 or b =±3
Therefore the given vectors are orthogonal for b = 0,±3.

Step-by-step explanation:
yea pretty much u just look at the letters (names of triangles)
The answer is angle JKL is 54 degrees
You multiply all the sides so if there are three sides u multiply them tother
If you multiply the number of students times 8 you get 96, but if you multiply the students by 8 you need to multiply the adults by 8 as well. Which leaves you with 16 adults. Is there more to this equation? I feel like this is only part of it.
