Answer:
x = -16
5x = -80
1. divide 5 on both sides.
2. x = -16
Answer:
7×+14=56

V =

r^2h/3
V = 3.14 x 4^2 x 6/3 (remember r is 1/2 of the diameter)
V = 3.14 x 16 x 2
V = 100.5

= 1533</span>
When the dept of the water is 3/5 of the height of the cone, the radius of the water's surface is 3/5 of the radius of the cone: 1.2 ft. The rate of change of depth is equal to the rate of change of volume divided by the area of the surface:
dh/dt = (dV/dt)/A = (dV/dt)/(π·r²)
= (3/2 ft³/s)/(π·(1.2 ft)²)
= 25/(24π) ft/s ≈ 0.3316 ft/s
