First, Multiply 77.1 by 8 to find how many feet the submarine has dived.
77.1 × 8 = 616.8
Since the question is asking the submarines position "in relation to the surface," this number needs to be negated.
616.8 ⇒ -616.8
<h2>Answer:</h2>
<u>The submarine is at </u><u>-616.80 ft</u><u> in relation to the surface, so </u><u>option B</u><u> is correct.</u>
F(x)= (x+1)^2
f(-2)= ((-2)+1)^2
= (-1)^2
= 1
The ratio of the model's height to actual height of tower is 1:725
Step-by-step explanation:
Given
Actual height of Sears Tower =
= 1450 feet
Height of Model =
= 24 inches
We can divide the actual height by the model's height to find the scale
Let z be the ratio of the height of the model to the actual height

The ratio should be in same unit.
We know that
1 ft = 12 inches
Then

Hence,
The ratio of the model's height to actual height of tower is 1:725
