Hi
24% of 80 is 19.2
100% ⇒ 80
24% ⇒ x
100x = 24·(80)
100x = 1920
x = 1920/100
x = 19.2
Answer: (-0.4, 6.8)
The graph is attached
Step-by-step explanation:
We can find the axis of symmetry using the formula x = -b/2a
x = - -4/2(-5)
x = 4/-10
x = 0.04
Substitute for x and calculate y
y = 
y = 6.8
Here you have to use proportionality,
1 feet is 12 inches so 40 feets is 480 inches
Then the real locomotive is 480/16=30 times wider then the model
And then a window on the real locomotive is 30 times wider then the model..
