Answer:

The correct option is 4.

Step-by-step explanation:

The volume of a cylinder is

$V=\pi r^2h$

where, r is radius of the base and h is height of the cylinder.

It is given that the radius of the cylindrical sandbox is 2 ft and the volume of cylindrical sandbox is 18.84.

$18.84=(3.14)\times (2)^2\times h$ $[\because \pi=3.14]$

$18.84=(3.14)\times 4\times h$

$18.84=12.56\times h$

$\frac{18.84}{12.56}=h$

$1.5=h$

The height of the sandbox is 1.5 ft. Therefore the correct option is 4.

The annual energy consumption of the town where Camilla lives increases at a rate that is proportional at any time to the energy

vesna_86 [32]

Answer:

The town's annual energy consumption will be of 6.57 trillons of BTU after 9 years.

Step-by-step explanation:

The annual energy consumption of the town where Camilla lives increases at a rate that is proportional at any time to the energy consumption at that time.

This means that the consumption after t years is given by the following differential equation:

$\frac{dC}{dt} = kC$

In which k is the growth rate.

The solution is, applying separation of variables:

$C(t) = C(0)e^{kt}$

In which C(0) is the initial consumption.

The town consumed 4.4 trillion British thermal units (BTUs) initially.

This means that $C(0) = 4.4$

So

$C(t) = C(0)e^{kt}$

$C(t) = 4.4e^{kt}$

5.5 trillion BTUs annually after 5 years.

This means that $C(5) = 5.5$ . We use this to find k. So

$C(t) = 4.4e^{kt}$

$5.5 = 4.4e^{5k}$

$e^{5k} = \frac{5.5}{4.4}$

$e^{5k} = 1.25$

$\ln{e^{5k}} = \ln{1.25}$

$5k = \ln{1.25}$

$k = \frac{\ln{1.25}}{5}$

$k = 0.0446$

So

$C(t) = 4.4e^{0.0446t}$

After 9 years?

This is C(9). So

$C(9) = 4.4e^{0.0446*9} = 6.57$

The town's annual energy consumption will be of 6.57 trillons of BTU after 9 years.
