Answer:

(a) x = 0

(b) x = -300

(c) x = -450

Explanation:

Given

See attachment for complete question

Solving (a): The elevation at the surface level:

Let x represents the elevation

At the surface level, the elevation is 0.

So:

x = 0

Solving (b): Swim down 300ft:

A downward movement will be represented as negative.

So, the new elevation is:

New = Old - Distance\ Moved

Where

Old = 0 --- previous value of x

Distance\ Moved = 300

This implies that:

x = 0 - 300

x = - 300

<em>The new elevation is -300ft</em>

<em></em>

Solving (c): Swim down 150ft:

A downward movement will be represented as negative.

So, the new elevation is:

New = Old - Distance\ Moved

Where

Old = -300 --- previous value of x

Distance\ Moved = 150

This implies that:

x = - 300-150

x = -450

<em>The new elevation is -450ft</em>

  • <em>Preschool:</em> Where the individual understands the difference between initiative and guilt.
  • <em>Pre-Adolescence:</em> Where the individual learns about industriousness and inferiority.
  • <em>Adolescence:</em> Where the individual struggles between identity and confusion.
  • <em>Young Adulthood:</em> Where the individual deals between intimacy or isolation
  • <em>Middle-Adulthood:</em> Where the individual confronts the challenge of trying to make the difference.
