c) 4. If p : 9 = 3:2 and q: r = 3:4, then p : r is equal to
Answers
Answer:
yes
Step-by-step explanation:
By Section Formula
coordinates of R are:
R=(
m+n
5m+3n
,
m+n
4m+2n
,
m+n
−6m−4n
)
we have coordinates of R=(9,8,-10)
Therefore,
9=
m+n
5m+3n
9m+9n=5m+3n
−6n=4m
n
m
=
2
−3
Therefore R divides PQ in 3:2 ratio and negative sign indicates,it cuts Externally.
Therefore option (B) is Correct.
