Answer:
1.2
Step-by-step explanation:
Gradient = y2-y1/x2-x1
Coordinates = (4,6), (-16,-18)
-18 - 6/-16 - 4
-24/ -20
= 1.2
Hope it helps.
Answer:
for 2. I don't think it can be a triangle
The pressure at a certain height is the pressure at sea level plus the hydrostatic pressure.
P = 80 psi + ΔP
where
ΔP = ρgh
ρ is the density of water equal to 62.4 lbm/ft³
ΔP = (62.4 lbm/ft³)(1 lbf/lbm)(4*10 + 2 ft)(1 ft/12 in)² = 18.2 psi
Thus,
P = 80 + 18.2
<em>P = 98.2 psi</em>
The answer to your problem is 54.
