Calculation:
Enter the day values on
Figure (1)
The scatter plot will be as follows.
Figure (2)
b)
To find: The equation of best fit sine curve and superimposed it on the scatter plot.
The equation is
Calculation:
Use the
The equation is,
The superimposed graph is as follows.
Figure (3)
Figure (4)
Therefore, the equation is
c)
To find: The approximate number of days from apogee to apogee.
The approximate number of days from apogee to apogee is
Calculation:
The number of days from apogee to apogee is the period of the sine regression which is
Therefore, this is very close to the fact that the moon orbits the Earth once every
d)
To find: The approximate distance at perigee.
The approximate distance at perigee is
Calculation:
Use the
The perigee is about
Therefore, the approximate distance at perigee is
e)
To find: The date on which on which Moon is 359000 km from Earth and also explain the reason.
The date is day
Calculation:
The distance of
Therefore, the date is day

Roman and Shanice come along in a truck to help pull her out. They attach one end of a tow strap to the front of the car and the other end to the truck's trailer hitch, and the truck starts to pull. Meanwhile, Roman and Shanice get behind the car and push. The truck generates a horizontal force of 377 lb on the car. Roman and Shanice are pushing at a slight upward angle and generate a force of 119 lb on the car. These forces can be represented by vectors, as shown in the figure below. The angle between these vectors is 20.2°. Find the resultant force (the vector sum), then give its magnitude and its direction angle from the positive x-axis. 119 lb 20.2° 377 lbarrow_forward
