A big ship drops its anchor.

Question

The variable l models the anchor's elevation (in meters) relative to the water's surface t seconds after the ship drops its anchor.
l=-2.4t + 75
What is the initial height of the anchor?

Answer 1

The initial height of the anchor refers to the height at t=0 seconds, which can be found by substituting t=0 into the equation l=-2.4t + 75.

l = -2.4(0) + 75
l = 0 + 75
l = 75

Therefore, the initial height of the anchor is 75 meters.
