Answer:
Step-by-step explanation:
option (d) 4hrs 40mins
B - 4.2 < -7.5
subtract b and 4.2
less then sign is <
then <-7.5
I think you have to first separate the integral:1/(1+v^2) + v/(1+v^2),
so the integral of the first term is ArcTan (v) and for the integral of the second term i recommend you to do a change of variable:
y= 1+v^2
so
dy= 2v
and
v= dy/2and then you substitute:v/(1+v^2) = (1/2)(dy/y)
and the integral is
(1/2) (In y)finally you plug in the initial variables:
(1/2)(In [1+v^2])
so the total integral is:
ArcTan (y) + (1/2)(In [1+v^2])
Answer:
The leghts of AB is 9 because both of the triangles are symmetrical. But also, this is a Equilateral triangle, which means that both of the sides are the same lengths (AB=AC)
Answer:
B
Step-by-step explanation:
multiply 18% and 220 which is 39.6
subtract 39.6 from 220 which is 180.4
simplify
