Answer: f(x)=5x^2-4x+5

Step-by-step explanation:

A quadratic function is as following; ax^2+bx+c

Joseph wants to line his garden with a fence that cost $2.25 per foot. The length of the garden is 6 yards and the width is 2.5
Galina-37 [17]

Answer:

$38.25

Step-by-step explanation:

Perimeter of a rectangle = 2W + 2L

(where W is the width and L is the length)

Given:

  • width = 2.5 yd
  • length = 6 yd

⇒ perimeter = (2 x 2.5) + (2 x 6)

                     = 5 + 12

                     = 17 yd

Given:

  • cost of fence = $2.25 per foot

⇒ total cost = 17 x 2.25

                    = $38.25

Bailey saves money at the end of each month. The function f(x) = 10x + 50 models the total amount he has saved after 'x' months.
kozerog [31]

Answer:

  • D) all non-negative integers

Step-by-step explanation:

The function f(x) = 10x + 50 models the total amount he has saved after 'x' months.

The domain is x-values, which is the number of the months.

x can only be zero or positive integers (since you can save after the month is complete), therefore the last option is correct.
