veronica works each day and earns more money per hour the longer she works. write a function to represent a starting pay of $20 with an increase each hour by 5%. determine the range of the amount veronica makes each hour if she can only work a total of 8 hours.

20 ≤ x ≤ 28.14
20 ≤ x ≤ 29.55
20 ≤ x ≤ 26.80
20 ≤ x ≤ 25.53

The range of the amount Veronica makes each hour if she can only work a total of 8 hours is 20 ≤ x ≤ 29.55

Solution:

Let us assume that Veronica worked x hours

The starting pay is

Each hour increase is

So the function is

Now if she works 8 hours, she will earn,

So, the range will be 20 ≤ x ≤ 29.55

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

where is the rest of the
