A cable installer charges $40. an hour plus a $50.00 service charge. Figure the function c(h) = ?

Hitman42 [59]

Answer:

c(h) = 40*h + 50

Step-by-step explanation:

Let h be the variable that represents the number of hours

As the cable operator charges $40.00 for an hour so for h hours, the expression will be 40*h

And

Lastly, he has to charge $50.00 must as service charge,

As the number of hours is variable here so the function will be in terms of hours.

So the resulting function will be:

c(h) = 40*h + 50

balu736 [363]

Answer:

The area of each section of the circle is $A=25\pi\ m^{2}$

Step-by-step explanation:

we know that

Each section represent a quarter of circle

The area of a quarter of circle is equal to

$A=\frac{1}{4}\pi r^{2}$

we have

$r=10\ m$

substitute

$A=\frac{1}{4}\pi (10)^{2}$

$A=25\pi\ m^{2}$
