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>

wat
Answer:
6,000 meters
Step-by-step explanation:
Length of one lap d = 400 m
Lee's speed = u = 7.2 km/h. Shelby's speed v = 9 km/h
After time t, Shelby will run x meters to cover exactly 3 more laps than Lee.
So x = vt
and
x - 3d = ut
Note t = x/v, then
x - 3d = x*u/v
x (1 - u/v) = 3d
x = 3d/(1 - u/v) = 3*400/(1 - 7.2/9) = 6,000 meters
Answer:
x⁶ +30x⁵ +375x⁴ +2500x³ +9375x² +18750x +15625
Step-by-step explanation:
The expansion is the sum of C(6, k)·x^(6-k)·5^k for k=0–6, where ...
... C(6, k) = 6!/(k!(6-k)!)
For k = 0–6, C(6, k) = {1, 6, 15, 20, 15, 6, 1}
Then the expansion is ...
... x⁶ +6·5¹·x⁵ +15·5²·x⁴ +20·5³·x³ +15·5⁴·x² +6·5⁵·x +5⁶
