The relationship between the number of hours a plumber works and the total work fee she charges is proportional. her fee for 5 hours of work is $350. which of the following could be combinations of values for the plumber's work hours and total work fee she charges?

Solution:

As given,  relationship between the number of hours a plumber works and the total work fee she charges is proportional.

The meaning of proportional is Ratio of number of hours a plumber works and the total work fee she charges is constant.

Using Unitary method

5 hours of work = $350

1 hours of work = $70

Let number of hours worked = x hours

Amount earned for x hours of work is represented by = $ y

For , x hours of work amount earned = 70 x (x=1,2,3...)

→y= 70 x

→→

step-by-step explanation:

find the angular size of the equatorial radius of the earth, if the horizontal parallax of the sun

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
