Answer:
2400
Step-by-step explanation:
half of 4800 is 2400
The vertex point would be (1,3)
explanation:
-b/2a:
-(-2)/2(1)
2/2=1
Plug 1 in for all the X’s
y=1^2-2(1)+4
y=3
licorice cost $6.59 a pound
how much would it cost to buy a quarter pound of licorice
$6.59 / 4 = 1.6475
a quarter pound of licorice
$1.65
Both distances 3966 and 4746 were done in 6 hours, so the speeds are:
speed against wind = 3966/6=661 km/h (difference of airplane and wind)
speed with wind = 4746/6=791 km/h (sum of airplane and wind)
The speed of airplane is greater than that of the wind, so this is a sum and difference problem.
Greater speed (plane) = (sum+difference)/2=(791+661)/2=726 km/h
Lesser speed (wind) = (sum-difference)/2 = (791-661)/2 = 65 km/h
$69.24 is the correct answer because 56.75 multiplied by 1.22 is 69.24
