First we find the factors
a^3-8 is the differnce between 2 perfect cubes and is factored out to
(a-2)(a^2+2a+4)
the factors are (a-2) and (a^2+2a+4)
a^4+16
this is not factorable, unless you mistiped it and it was really a^4-16
the factor is 1
a^3+2a^2+4a
factor out the a
a(a^2+2a+4)
this is the most factored out form
the factors are (a) and (a^2+2a+4)
there are no common factors except 1 so 1 is the answer
The Answer Is About 38.46%.
Answer:
(64/5)π units²
Step-by-step explanation:
The area of this sector would be:
Given central angle
------------------------------ *(area of whole circle)
2π rad
In this case, the area of the sector is:
(8/5) π rad
------------------------------ * π(4 units)^2
2π rad
and this reduces to:
(4/5) * π*16 units² or (64/5)π units²
Answer:
Step-by-step explanation:
The current that flows through most substances is directly proportional to the voltage V applied to it. The German physicist Georg Simon Ohm (1787–1854) was the first to demonstrate experimentally that the current in a metal wire is directly proportional to the voltage applied: I∝V I ∝ V .
