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>
Answer: the third one down
26 miles times 5,280 feet
Step-by-step explanation:
Look at the units. Miles over miles will cancel, leaving feet... 1 mile is 5,280 feet, because a mile is bigger than a foot, and there are 5,280 feet per 1 mile.

Answer:
6
Step-by-step explanation:
3x-4=14
3x=14+4
3x=18
x=6
Diagonal angles have the same measure - not sure what u mean by oposite.
