Answer:
(0,0)
Step-by-step explanation:
x value of vertex = -b/2a
ax^2+bx+c
-2x^2+0x+0 sinc you have no value of b & c in your quadratic function
-b = 0
2a = (2)(-2)
-b/2a = (0/-4) = 0
x value of the vertex = 0
plug 0 in for all values of x in the function to find y coordinate value
-2(0)^2 = 0
(x,y) = (0,0)
Whole-wheat bread = $2.06/lb
We need the cost of 3.8 lbs of whole-wheat bread.
So, we simply need to multiply the cost with the amount needed.
(cost per pound) × (amount of bread)
($2.06) × (3.8)
Simplify.
$7.828
Round to the nearest tenths.
$7.83
So, 3.8 pounds of whole wheat bread costs $7.83
