Answer:
Initial height of the anchor is 75 meters.
Step-by-step explanation:
We are given the following in the question:
where, I is the anchor's elevation in meter after t seconds dropped from the ship.
We have to find the initial height of anchor that is we have to put t = 0 in the equation.
Putting t = 0, we get,
Thus, initial height of the anchor is 75 meters.
The answer is the last option:
Explanation:
1. You have that the equation of the line is:
Where is the slope of the line and
is the intercept with the y-axis.
2. Therefore, you must find .
3. Then, you must substitute the points given in the problem and the slope into the equation of the line and solve for , as following:
