Step-by-step explanation:
Answer:
(a) 13536.10J
(b) 27072.20J
Step-by-step explanation:
(a) Height of tank (h) = 4 feet = 4/3.2808 = 1.22m
Volume of water in full tank = 4ft×5ft×4ft = 80ft^3
Volume of water in half tank = 1/2 × 80ft^3 = 40ft^3
Density of water = 62.4lb/ft^3
Mass of water = density × volume = 62.4 × 40 = 2496lb = 2496×0.45359kg = 1132.16kg
Work done to empty half of the tank = mgh = 1132.16×9.8×1.22 = 13536.10J
(b) Work done to empty all of the tank = 2 × work done to empty half of the tank= 2 × 13536.10J = 27072.20J
Answer: slope = 6
Step-by-step explanation: Your y’s are increasing by 12, while the x’s are increasing by 2. Therefore using rise/run, 12/2 = 6.
<span>The correct option is: A. f(x) = 4sin(x − π/2), because:
</span>
1. When you evaluate x=π/2 in the function f(x) = 4sin(x − π/<span>2), you obtain:
</span>
f(π/2) = 4sin(π/2− π/2)
f(π/2) = 4sin(0)
f(π/2) = 4(0)
f(π/2) = 0 (As you can see in the graphic)
2. If you evaluate x=π in the same function, then you have:
f(π) = 4sin(π− π/2)
f(π) = 4sin(π/2)
f(π) = 4 (As it is shown in the graphic)
