7800 because it grows 300 per 2 hours so 3000 + 4800 = 7800
The motion of the mass as it moves on the bottom of the spring is a
repetitive motion.
Reasons:
The general form of the equation of the simple harmonic motion of the
mass is <em>d</em> = a·sin(ω·t)
Where;
d = The distance of the mass from the rest position
a = The maximum displacement of the mass from the equilibrium position = 6 cm
ω = The frequency of rotation
t = The time of motion
ω = The frequency of rotation

Where;
T = The time to complete one cycle (the period of oscillation) = 4 seconds

Combining the above values gives the modelling equation as follows;

What’s the point?
y=mx+b
m is the slope
y=5x+b then you substitute the point (x,y) on y and x to find b
Given:
The equation of parallel line is
.
The line contains the point (-1,1).
To find:
The equation of the line.
Solution:
The slope intercept form of a line is:

Where, m is the slope and b is the y-intercept.
The equation of parallel line is

It can be written as

The slope of this line is 0.
The slopes of two parallel lines are always equal. So, the slope of the required line is also 0. It passes through the point (-1,1) so the equation of the line is:




Therefore, the equation of the required line is 1.
