1/2 I think. I'm not sure, but I think it's 1/2. Because if you divide 14 by two you get seven. Seven is HALF of 14.
Answer:
77 feet below sea level.
Step-by-step explanation:
Since y is the time the submarine is ascending, we can plug it in for y and find our answer. We can create an equation where D is the depth and y is time ascending: D = -230 + 17y
Substitute 9 for y:
D = -230 + 17(9)
D = -230 + 153
D = -77
The depth of the submarine after 9 minutes will be 77 feet below sea level. Hope this helps, and Brainly will be highly appreciated.

Answer:
h = 7.1 cm
Step-by-step explanation:
To find the height of the triangle, we can first find the area of the triangle using the Heron's formula:

Where a, b and c are the sides of the triangle and p is the semi perimeter of the triangle:

So the area of the triangle is:


Now, to find the height, we can use the following equation for the area of the triangle:

The height draw in the figure is relative to the side of 17 cm, so this side is the value of base used in the formula. So we have that:



Rounding to the nearest tenth, we have h = 7.1 cm
