Answer:

c = 16.392\,\frac{USD}{ft^{2}}

Step-by-step explanation:

The surface area of the cone shaped roof is:

A_{s} = \pi\cdot (10\,ft)\cdot (6\,ft)

A_{s} \approx 188.496\,ft^{2}

The cost of roofing per square feet is: (USD stands for US dollar)

c = \frac{3089.76\,USD}{188.496\,ft^{2}}

c = 16.392\,\frac{USD}{ft^{2}}

Georgia [21]

Answer:

The Given situation is In 2005, the shabelle river in Somalia rose an estimated 5.25 inches every hour for 15 hours.

Increase in water level is represented by the function,f(x)=5.25 x.

or replacing f(x) by y we get ,y= 5.25 x

This is equation of straight line passing through the origin.

As x is number of hours , so x> 0,(0,∞] Which is it's domain.

As x> 0, so Range is those values of y for which x is defined.

x= \frac{y}{5.25},So Range is y>0 i.e (0,∞}

As the function has no breaking point , that is when you plot the graph on coordinate axis there is no breaking point.So , it is everywhere continuous i. e for all values of x.
