malfutka [58]

The statement that are important when representing functions are:

It is important to explain what your variable represents and to include units.

Functions may depend on more than one variable.

<h3>What is are functions?</h3>

A function can be described as the relation between a set of inputs that have one output each. it help to display the relationship between inputs in a case whereby each input is related to exactly one output.

We can denote the function by f(x) where x is the input.

The angle θ=π/6 is in standard position and has a terminal side that coincides with the graph of a proportional relationship rep

victus00 [196]

Answer:

a) $k \approx \frac{\sqrt{3}}{3}$ , b) $\left(\frac{\sqrt{3}}{3}, \frac{1}{3} \right)$

Step-by-step explanation:

a) The constant of proportionality is:

$k = \frac{y}{x}$

$k = \tan \theta$

$k = \tan \frac{\pi}{6}$

$k \approx \frac{\sqrt{3}}{3}$

b) The ordered pair is:

$\left(\frac{\sqrt{3}}{3},\frac{\sqrt{3}}{3}\cdot \frac{\sqrt{3}}{3} \right)$

$\left(\frac{\sqrt{3}}{3}, \frac{1}{3} \right)$

The Lisbon’s new heat pump cost $4,500.

Alex73 [517]

Answer:

4.1 years.

Step-by-step explanation:

We have been given that The Lisbon’s new heat pump cost $4,500. They bought it to replace their old furnace and air conditioner which cost about $2,800 a year to run. The heat pump will save them approximately 39% a year.

Yearly cost was 2800 at first and the pump will save 39% of 2800. So annual saving with new heat pump will be:

$\frac{39}{100}*2800=0.39*2800$

Let x be the number of years in which heat pump will pay for itself, so saving in x years will be:

$0.39*2800*x$

Now let us equate the savings by new heat pump with cost of heat pump to find the number of years (x).

$0.39*2800*x=4500$

$1092*x=4500$

$x=\frac{4500}{1092}$

$x=4.1208791208791209\approx 4.1$

Therefore, the heat pump will pay for itself in 4.1 years.
