investigation of simple harmonic motion ( see attachment)
there are two common forms of the equations used to model simple harmonic motion (shm), which is the motion of springs, swings, tides, and many other periodic phenomena. these equations are and , where:
suppose you are an engineer trying to recreate an experiment involving a weight on the end of a spring. this simulation will give you an idea of what the experiment will look like. for more information, you can visit this simple harmonic motion website.

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
