Answer:
Option 4 (±1, ±1/3, ±3, ±9) is the correct option.
Step-by-step explanation:
The given expression is
We have to find the possible rational zeros for the function.
So by the rational zero theorem factors will be
=±(Factors of constant term 9)/±factors of coefficient of
=±(Factors of 9)/±(Factors of 3)
=±(1, 3, 9)/±(1, 3)
=±(1, 3, 9, 1/3)
So option 4 is the correct answer.
<em><u>The surface area of cylinder in standard form is:</u></em>
<em><u>Solution:</u></em>
Given that,
Radius of cylinder = 2x + 3 inches
Height of cylinder = 3 times radius = 3(2x + 3)
Height of cylinder = 6x + 9 inches
<em><u>The surface area of cylinder is given by formula:</u></em>
Where, "r" is the radius and "h" is the height of cylinder
<em><u>Substituting the given values we get,</u></em>
Thus the surface area of cylinder in standard form is found
