Answer:
A. Here the y-intercept is (0,4) and means at time 0 hours the fish is displaced 4 feet.
B. For every hour, the fish is displaced 60 more feet.
C. The domain is [0, 12].
Step-by-step explanation:
Part A:
The y-intercept is where the function intersects the y-axis. It is the point (0,b) and is always the starting value in real world situations since time begins at x=0. Here the y-intercept is (0,4) and means at time 0 hours the fish is displaced 4 feet.
Part B:
The average rate of change is the slope of the function found using the formula . Use the points (0,4) and (1,64).
For every hour, the fish is displaced 60 more feet.
Part C:
The domain is the set or group of x values in the function. Time starts at 0 and goes until the fish traveled 724 feet. What time is this at?
The function has the equation y = 60 +4. Find the time by substituting y=724.
724=60x+4
720 = 60x
12=x.
The domain is [0, 12].

Answer:
4.68° south east 317.36 km
Step-by-step explanation:
We can find the angle between the two distances (vectors) because according to the diagram, we can draw two right triangles between them.
The complement of the 36 degree angle is 54 (90-36=54), and the complement of the 68 angle is 22, (90-68=22) the sum of 22 and 54 is 76. So the angle between the two distances is 76.
Then we apply the cosine law
then we apply the sin law
and because in any triangle, the sum of the inside angles is equal to 180
180= 76+C+(68+Y)
y=180-76-C-68
So the emergency plane has to travel 317.36 km, 4.68° southeast.
