Answer:
Thanks very much ^^
Step-by-step explanation:
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>
The gardens perimeter is 12 meters.
Explanation:
- The garden has a 4m length and a 2m width. The perimeter of any given rectangle is two times the sum of the length and the width of the same rectangle.
- Perimeter = 2 × (length of the rectange + width of the rectangle)
Perimeter = 2 × (4m + 2m) = 2 × (6m) = 12 meters.
- So the gardens perimeter is equal to 12 meters.
- Ramond needs to buy a fence for a garden whose parameter is 12 meters.
