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
AnswerdV/dt = 4·pi·(40)2·(-2)
Step-by-step explanation:
Step-by-step explanation:
By using formula of h^2=p^2+b^2
h=20
p=x
b=10
Now,
p=root h^2-b^2
x=root 20^2-10^2
x=root 400-100
x=root 300
x= 10root3
Answer:
:))
Step-by-step explanation:
Collect like terms, keeping the integer rules in mind
5. 5a + 9b - 3a + 2b + 4a
5a + 4a - 3a + 9b + 2b (REARRANGE, if you find it to help)
6a + 11b
6. 7m + 3n - 8m + 2n + 10m
7m + 10m - 8m + 3n + 2n
9m + 5n
10. 10m²n + 5mn + 9m²n - 2mn
10m²n + 9m²n + 5mn - 2mn
19m²n + 3mn
Try to do the rest on your own :)
