Answer:

Initial height of the anchor is 75 meters.          

Step-by-step explanation:

We are given the following in the question:

l(t)=-2.4t+75

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,

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

Thus, initial height of the anchor is 75 meters.

A woman standing on a hill sees a flagpole that she knows is 40 ft tall. the angle of depression to the bottom of the pole is 14
NemiM [27]
Let distance form the pole = x  and height of the hill = y ft

now we can set up 2 equayions 
tan 18 = (40-y)/x
tan 14 = y/x

from second equation y = sxtan14  so we have:-
 tan 18  = ( 40 - x tan 14) /  x

x tan 18 = 40 - x tan 14
x(tan 18 + tan 14) = 40

x   = 40 / (tan18 + tan 14)  =  69.66 feet Answer

SVETLANKA909090 [29]
Starting January 1, 2015, there are 364 remaining nights.
From 1,001 nights, it will be 637 nights left.

In 2016, there are 366 nights. Subtract it to 637 nights left, you will get 271 nights left.
In 2017, 271 is lesser than 365.
From January to August, the nights left is 28.
<span>
So the date will be September 28, 2017.</span>
