Answer:
0.00318 ft/s
Explanation:
Volume of the inflatables swimming pool, V = πr²h
V = πr²h
a) (dh/dt) = (dh/dV) × (dV/dt)
V = πr²h
(dV/dh) = πr²
(dh/dV) = (1/πr²)
So, we require the rate of change of depth when diameter = 8 ft, radius = (diameter)/2 = 4 ft
(dh/dt) = (dh/dV) × (dV/dt)
(dh/dV) = (1/πr²) = (1/π(4²)) = 0.0199 ft⁻²
(dV/dt) = 0.12 gal/s = 0.016 ft³/s
(dh/dt) = (0.0199 × 0.016) = 0.00318 ft/s

Answer:
Explanation:
component of force along the ramp
= 370 cos θ where θ is the slope of the ramp with respect to ground.
sinθ = 1.4 / 5
θ = 16 degree
370 cos16
= 355.67 N
Work done
= component of force along the ramp x length of the ramp
= 355.67 x 5
= 1778.35 J
Answer:
False
Explanation:
According to USA today "Though nearly 60% of the 18 to 21 year olds surveyed said they have a job, and 70% of the 22 to 26 year olds said the same, many seem to rely on mom and dad to fund non-essential expenses. Nearly 75% of the 18 to 21 year olds and more than 40% of 22 to 26 year olds said their parents pay their monthly cell phone bill. Just 54% of 22 to 26 year olds own or lease their own car; and 43% of 22 to 26 year olds are living at home with their parents."
