The distance between them is 75 miles
after 1 hour the train will go 125 miles
125 miles.....1 hour
75 miles..........x hour
x=75/125=75/125*60=36 minutes
d is the answer
in short, you simply pick a few random "x" values, to get the "y", and that's your point, for example say x = 2, then y = -(2)² - 4 => y = -8, that gives us the point of (2, -8), and so on.
we can start off by finding the vertex, the U-turn of the graph, and then just pick a point to its left side and a point to its right side, and we can get the vertex of that by
and since it's a vertical parabola, the axis of symmetry comes from the x-coordinate of the vertex, namely x = 0, check the picture below.
Answer:
15.7
Step-by-step explanation:
Circumference = πd
π = 3.14
d = diameter (5 feet)
C = 3.14(5)
C = 15.7
Answer:
2 4/5 feet
Step-by-step explanation:
let 'x' = height of fire hydrant
7/20 = x/8
cross-multiply:
20x = 56
x = 56/20 or 14/5, which is 2 4/5
