In Exercises 15-42, translate each argument into symbolic form. Then determine whether the argument is valid or invalid. You may use a truth table or, if applicable, compare the argument’s symbolic form to a standard valid or invalid form. (You can ignore differences in past, present, and future tense.) If I’m at the beach, then I swim in the ocean. If I swim in the ocean, I swim I feel refreshed . ∴ If I'm not at the beach, then I don't feel refreshed .

Solution Summary: The author explains that each argument into symbolic form and determine whether it is valid or invalid.

If I’m at the beach, then I swim in the ocean.
If
I
swim
in
the
ocean,
I
swim
I
feel
refreshed
.
∴
If
I'm
not
at

beach,
then
I
don't
feel
refreshed

A mass is suspended by a spring such that it hangs at rest 0.5 m above the ground. The mass is raised 40 cm and released at time t = 0 s, causing it to oscillate sinusoidally. If the mass returns to the high position every 1.2 s, determine the height of the mass above the ground at t = 0.7 s. (include graph)
At a certain ocean bay, the maximum height of the water is 4 m above mean sea level at 8:00 a.m. The height is at a maximum again at 8:24 p.m. Assuming that the relationship between the height, h, in metres, and the time, t, in hours, is sinusoidal, determine the height of the water above mean sea level at 10:00 a.m.(include graph)
A Ferris wheel of diameter 18.5 m rotates at a rate of 0.2 rad/s. If passengers board the lowest car at a height of 3 m above the ground, determine a sine function that models the height, h, in metres, of the car relative to the ground as a function of the time, t, in seconds.(with graph)
