The area of the first surface is given to be
Recall that for any scalar
and vectors
,
which means
So it follows that the area of the
is 16 times that of
.
Basically, take the union of both domains
g(x)=x/(1-x)
1-x=0
1=x
x=1 is restricted because it makes you divide by 0
f(x)=(1-x)/(1+x)
1+x=0
x=-1
x=-1 is restricted because it makes you divide by 0
domain is all real numbers except -1 and 1
Independent because what you get in the first one doesn't effect the second
Answer:
To get the x-intercepts of the function, f(x) = 4x2 – 24x + 20
It has to be equated to zero and the values of x are the x-intercepts. So,
4x2 – 24x + 20 = 0
The resulting equation is a quadratic equation which can be solved by different methods. The solution is
x = 5, 1
The average therefore is:
(1+5/)2 = 3
