19 feet
convert 2 into an improper fraction
2 =
hence the length of the wall is 19 feet
The depth of a scuba diver can be modeled by the equation d 0.5t (3.5t- 28.25), where d is the depth in meters of the diver and
t is the time in minutes. Find the time it takes for the diver to reach the surface. Give your answer to the nearest minute.
1 answer:
We know that
using a graph tool
see the attached figure
<span>The diver reaches the surface when d = 0
</span>so
<span>0.5t (3.5t- 28.25)=0---------> the solution is
0.5t=0--------> t=0
and
</span><span>(3.5t- 28.25)=0----------> 3.5t=28.25--------> t=28.25/3.5--------> t=8.07 minutes
</span><span>
the time it takes for the diver to reach the surface is when the depth is zero
the time is 8 minutes
the answer is
8 minutes</span>

Hey there! I'm happy to help!
If you raise a fraction to an exponent, you apply that exponent to the numerator and the denominator. This would give us .
Have a wonderful day! :D
