Given an ODE

with initial condition

, the general process is to write the ODE as an integral equation,

By setting

for all

, we get the following recurrence for

.

From this we work towards finding a pattern for

so that we can find a solution of the form

.

Write this as the integral equation,

First step:



Second step:



Third step:



Fourth step:



You should already start seeing a pattern. Recall that

Multiplying this by 2 gives

which matches the solution we have for

except for that first term. So subtracting that, we find a solution of

with a domain of

.
Hopefully this gives some insight on how to approach the other two problems.
Answer:
Since the graph described will form a straight line, the concept of similar triangles can be used when comparing the slopes on AB and AC. We just imagine a triangle formed by the line segments and their corresponding x and y components. We can notice that their angles don't actually change so we know that the two triangles formed are proportional. This would mean that getting the slope (Δy/Δx) would yield us the same number.
PART B
The initial value of the graph is 60 meters and this represents the initial position of the shark (it is located 60 meters below the ocean surface).
100/1-60/0= 40
The slope of the graph is and this represents how fast (speed) the shark can dive. We know this because dividing meters over the number of minutes would give us meters/minute and this is describing the speed.
