Answer:
The submarine would be 900 below the ocean surface after 12 minutes assuming it started its descent at the surface of the ocean.
Step-by-step explanation:
The formula for distance traveled (in this case the distance a submarine descends) over a period of time is:
d
=
r
⋅
t
where
d
is the distance traveled (or descended),
r
is the rate of travel and
t
is the time.
In this problem we are told the rate,
r
is 75 feet per minute. And, we are told the time,
t
, to calculate for which is 12 minutes.
4 goes into 26 6 times with a remainder of 2.
26 ÷ 4 = 6 2/4
6 2/4 = 6 1/2
Your answer is 6 1/2

= 2(4x^2 - 25)
= 2(2x + 5)(2x - 5)
