Answer with explanation:

A motion is said to be Simple Harmonic motion if it is to and fro motion that is a type of periodic motion where motion of an object repeats after certain interval of time.

Option A:→ A police car shining a spotlight into buildings as it drives by is not a periodic motion because when a car is moving towards a spotlight does not repeat in a small duration.

Option B:→ Calculation of Angle of Elevation for a Building is not Simple Harmonic as it is not Periodic.

Option C:→ The motion of a piston is simple harmonic because when engine is in motion the piston moves up and down that is a Periodic motion.This motion is also called reciprocating motion as it is not completely periodic which can be converted into circular motion with the help of an Instrument called Crankshaft.

Option D: →A ball bouncing on a sidewalk is Parabolic of different Latus rectums .It's distance from base that is maximum height attained by ball starts decreasing when friction comes into play and stops when Inertia stops acting on the ball.

Option C:→ The motion of a piston is an example of simple harmonic motion.

If a polynomial function f(x) has roots 1+square root of 2 and-3, what must be a factor of f(x)?

nevsk [136]

To find the factor a a polynomial from its roots, we are going to seat each one of the roots equal to $x$ , and then we are going to factor backwards.

We know for our problem that one of the roots of our polynomial is -3, so lets set -3 equal to $x$ and factor backwards:
$x=-3$
$x+3=0$
$(x+3)$ is a factor of our polynomial.

We also know that another root of our polynomial is $1+ \sqrt{2}$ , so lets set $1+ \sqrt{2}$ equal to $x$ and factor backwards:
$x=1+ \sqrt{2}$
$x-1= \sqrt{2}$
$x-1- \sqrt{2}=0$
$(x-(1+ \sqrt{2})=0$
( $(x-(1+ \sqrt{2} ))$ is a factor of our polynomial.

We can conclude that there is no correct answer in your given choices.
