Alright, so she drives 64.5*5 (for 5 days)=322.5 miles each week. She then uses 322.5miles/1 * 1gallon/21.5 miles (we have 1 gallon/21.5 miles because 1 gallon=21.5 miles and we have the gallon at the top to cross the miles out)=15 gallons. The cost per gallon is 2.85 (we add 2.85 for each gallon), and we have 15 gallons, so 2.85dollars*15l=42.75 dollars is our answer

Tatiana [17]

Answer:

<u>The area of the circular garden is 28.3 square feet</u>

Step-by-step explanation:

Let's recall that the area of a circle is π * r², therefore if the diameter of the circular garden is 6 feet, the area is:

Diameter = 6 feet ⇒ radius = (6/2) = 3 feet

Area of the circular garden = π * 3²

Area of the circular garden = 3.1416 * 9

Area of the circular garden = 28.2744

<u>Area of the circular garden = 28.3 square feet</u>

1a) f(x) = I x+2 I. This is a piece-wise graph ( V form)
      x = 0 →f(x) =2 (intercept y-axis)
      x = -2→f(x) = 0 (intercept x-axis)
      x = -3→f(x) = 1 (don't forget this is in absolute numbers)
      x = -4→f(x) = 2 (don't forget this is in absolute numbers)
Now you can graph the V graph

1b) Translation: x to shift (-3) units and y remains the same, then
      f(x-3) = I x - 3 + 2 I = I x-1 I
     the V graph will shift one unit to the right, keeping the same y. Proof:
     f(x) = I x-1 I . Intercept x-axis when I x-1 I = 0, so x= 1
