Answer:
She earns $6.50 from the Smiths which is 25 cents more than she earns at the Nelsons.
Step-by-step explanation:
To solve this problem you must find the hourly rate she earns at the Smiths. This will allow you to compare to the hourly rate that is given for the Nelsons. To find the Smiths hourly rate divide $39 by the 6 hours she babysat there. This will have the hourly rate. 39/6=6.5. This means she earns $6.50 an hour for the Smiths. When comparing the rates it is clear that she earned 25 cents more at the Smiths.
The area equals 38 because the total area is 40 and the area of the white part is 2 and 40-2=38 so the area of the green area is 38
Answer:
(Since polinomial functions are continuous)
(As this quadratic function has an absolute minimum, represented by its vertex)
Step-by-step explanation:
Graphically speaking, quadratic functions are represented by parabolas. In this case, we have a parabola in factorized form. From Theory of Functions, we get that domains of function represents the set of values of 
so that exist an image, whose set is known as range is represented by values of 
.
is represented by horizontal axis in the figure, whereas is represented by the vertical axis. By using this approach we get that domain and range of the function are, respectively:
(Since polinomial functions are continuous)
(As this quadratic function has an absolute minimum, represented by its vertex)
