(I'm assuming that this isn't multiple choice since you didn't include the answer choices.)
Falling at the rate of 2.5 m/s for 45 seconds, the anchor fell
(2.5 m/s) x (45 s) = 112.5 meters .
If it wound up only 40 meters underwater, then it must have fallen
(112.5 m - 40 m) = 72.5 meters
from its storage position on the big cruise ship,
before it ever reached the water.
Since it was falling at the rate of 2.5 m/s, it took
(72.5 m) / (2.5 m/s) = 29 seconds
to get down to the water surface after it started dropping.
Answer:
+ 25
Step-by-step explanation:
To complete the square
add ( half the coefficient of the x- term )²
the coefficient of the x- term is 5 and 5² = 25, hence
x² + 10x + 25 = (x + 5)² ← perfect square
