Answer:
The height of the building is 153.664 meter.
Step-by-step explanation:
Consider the provided function.

Here t represents the time v₀ represents the initial velocity, s₀ represents the initial height and s(t) represents the height after t seconds.
It is given that the splash is seen 5.6 seconds after the stone is dropped.
That means after 5.6 seconds height s(t) = 0, Also the initial velocity of the stone is 0.
Substitute respective values in the above function.



As height can't be a negative number so the value of s₀ is 153.664.
Hence, the height of the building is 153.664 meter.
One class is 45 minutes.
That's 90 minutes per week.
8 weeks times 90 minutes is 720 minutes.
720 minutes divided by 60 minutes in the hour is 12 hours. Answer C.
The key word here that you see is "about". Which means it is close but not exact. So when his teacher said that a liter is about .473 and his parents said it was "about" .5, you were rounding or estimating. .473, rounded to the nearest tenths is .5. Because "73" in .473 is closer to .5 or .500 than it is to .4 or .400.
Answer: B) 8•10^-1
Use the commutative property to reorder the terms.
(4•2)•(10^4 • 10^-5 )
Multiply the numbers. Multiply the terms with the same base by adding their exponents.
8•10^4-5
Calculate the difference and you get 8•10^-1
