Given y = 7/x² + 10
Let,
y = f(x)
f(x) = 7/x² + 10
And,
g(x) = x²
Hence, f(g(x))
Reason is;
You have to rewrite f(x) so that it can fit in g(x) into the equation
f(x) = 7/g(x) + 10
Answer:
D.
Step-by-step explanation:
Take the vector u = <ux, uy> = <4, 3>.
Find the magnitude of u:
||u|| = sqrt[ (ux)^2 + (uy)^2]
||u|| = sqrt[ 4^2 + 3^2 ]
||u|| = sqrt[ 16 + 9 ]
||u|| = sqrt[ 25 ]
||u|| = 5
To find the unit vector in the direction of u, and also with the same sign, just divide each coordinate of u by ||u||. So the vector you are looking for is
u/||u||
u * (1/||u||)
= <4, 3> * (1/5)
= <4/5, 3/5>
and there it is.
Writing it in component form:
= (4/5) * i + (3/5) * j
I hope this helps. =)
