<h2>Answer:</h2>

$38 783.2

<h2>Step-by-step explanation:</h2>

The equation is:

25 000* $1.05^{9}$

(1.05 because 5% is 0.05 of the whole)

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.

Find a positive angle less than 360° that is coterminal with the given angle.

Naddik [55]

Answer:

The positive angle less than 360° that is coterminal with -215° has a measure of 145°.

Step-by-step explanation:

From Geometry, we know that angles form a family of coterminal angles as function of number of revolutions done on original angle. We can represent the set of all coterminal angles by means of the following expression:

$\theta_{c} = \theta_{o} + 360\cdot i$ , $i \in \mathbb{Z}$ (1)

Where:

$\theta_{o}$ - Original angle, in sexagesimal degrees.

$\theta_{c}$ - Coterminal angle, in sexagesimal degrees.

$i$ - Coterminal angle index, no unit.

If we know that $\theta_{o} = -215^{\circ}$ and $i = 1$ , then the coterminal angle that is less than 360° is:

$\theta_{c} = -215^{\circ} + 360\cdot (1)$

$\theta_{c} = 145^{\circ}$

The positive angle less than 360° that is coterminal with -215° has a measure of 145°.
