Answer:
here's the proof
Explanation:
x-1=0
x=1
so
f(x)=x⁴-2x³+x²-x+1
f(1)=1⁴-2.1³+1²-1+1
f(1)1-2+1-1+1
f(1)=2-2
f(1)=0
as we know When f(c)=0 then x−c is a factor of f(x)
hence x-1 is a factor of x⁴-2x³+x²-x+1

Answer:
iron ore
Explanation:
Iron ore are rocks from where the chemical element iron can be extracted.
Iron ore is not a product from rainforests. In fact, it is usually found in more arid areas. The two largest iron ore deposits in the world are arid or semi-arid, they are found in Northern Brazil and in Western Australia.
Answer:
the radius of planet B is times the radius of planet A
Explanation:
The surface gravity of a planet is given by
where
G is the gravitational constant
M is the mass of the planet
R is the radius of the planet
For the two planets in the problem, we have:
(same gravity)
(planet B has twice the mass of planet A)
So we can write
so, the radius of planet B is times the radius of planet A.
