Step-by-step explanation:

3 +6d+2d=24

3+8d=24

8d=21

d = 21/8

Step 4 one does not divide both sides by by 14

See solutions for detail.

Step-by-step explanation:

a. $\frac{dV}{dt}$ is the instantaneous rate of change of volume given with respect to time, t.

The volume's rate of change is written as a function of time.

- $\frac{dh}{dt}$ is the rate of change in the height of water in the tank with respect to time, t.

b. $\frac{dV}{dt}-$ is the only constant. Water flows into the constant at a constant rate, say 6cm^3 per minute.

c. $\frac{dV}{dt}$ is positive. Volume water in the take is increasing from time to time.

-The volume at time t=1 is greater than the volume at t=0, hence, it's a positive rate of change.

d. $\frac{dh}{dt}$ is a positive rate. The initial height of water in the tank is zero.

-The final height at time t is 0.25h. The height is increasing with time.

Hence, it is positive.
