Answer: He cannot see a ship that is 4.5 miles away.
Step-by-step explanation:
Since we have given that

Here, h is the eye level above the water
d is the distance away.
If h = 12 feet
We will get :

Hence, it is 10.39 feet away when eye level is 12 feet above the water.
Therefore , he cannot see a ship that is 4.5 miles away.
Answer:
4x^2 - 1 = 0
Step-by-step explanation:
x = 1/2, x = -1/2
2x = 1, 2x = - 1
2x - 1 = 0, 2x + 1 = 0
( 2x - 1 )( 2x + 1 ) = 0
4x^2 - 1 = 0
Answer: 0.77
Step-by-step explanation:
17/22 = 0.7727
To the nearest hundredth in math means to round off to two decimal places, so here, 2 is less than 5, and so the final answer is
= 0.77
