Answer: -11 meters
Step-by-step explanation:
so for the waters surface, we are going to call that 0. if bob is at 15 meters below 0, then -15+4=-11, so he would be at-11 meters in relation to the waters surface.

For a segment AB, the coordinates of the middle point C are:
xc=(xa+xb)/2,
yc=(ya+yb)/2.
Now, you know points A and C. Thus we get:
xb=2×xc-xa
yb=2×yc-ya
With numerical values:
xb=2×2-(-1)=4+1=5
yb=2×3-(-5)=6+5=11
Answer: B(5, 11)
Answer:
h = 2A/b
Step-by-step explanation:
Step 1: Write out triangle formula
A = 1/2bh
Step 2: Multiply 2 on both sides to get rid of fraction
2A = bh
Step 3: Divide both sides by <em>b</em> to isolate <em>h</em>
2A/b = h
Step 4: Rearrange
h = 2A/b
