Answer:
Step-by-step explanation:
Given lines in parametric form
line 

direction vector of
Line 
direction vector of
therefore

thus lines are parallel.
(ii)distance between two lines is
is given by
=s
=3s

where
=3
=-2
=-3
=-9
=6
=9
distance(d)=0 units since value of the matrix

is zero
There were (10500/1.25) = 8400 visitors in 2001.
Explanation:
An increase of 25% means multiplying by 1.25. So, if the visitors from 2001 are multiplied by 1.25, then the result is 10500. Thus, the amount from 2001 was 10500/1.25=8400
Answer:
x = 30'
2x = 60'
3x = 90'
Step-by-step explanation:
2x + 3x + x = 180
6x = 180
6x ÷6 = 180 ÷ 6
x = 30'
therefore
2x = 60"
3x = 90'
