Part A : The coefficients in the expression are "8" and "15. The variables in the expression are "h" and "t".
Part B: There are actually two terms in the expression and they are "8h" and "15t". Terms are separated by a plus sign or a minus sign.
Part C: "15t" is the term in the expression that shows the total earned for tablets sold.
Well, you would need to do 195x4 and you would get 780, I believe. So 780 divided by 4 is 195.
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.
