(3,452 * 2) = round trip = 6,904.
6,904 * 3 = total distance = 20,712.
Therefore, the final answer is 20,712 miles.
In order to figure out the horizontal distance Raymond travels using his zip cable, we may simply apply Pythagoras theorem which is, for a right triangle:
hypotenuse² = base² + height²
base = √(hypotenuse² - height²)
base = √(65² - 52²)
base = 39 yards
Raymond will travel a horizontal distance of 39 yards.
Let x be the length of the train.
On the basis of the observer;
Speed of the train = x/6
On the basis of the bridge;
Total distance covered by any point of the train= 350+x
Speed = (350+x)/20
Equating the two expressions of speed;
x/6 = (350+x)/20
20(x) = 6(350+x)
20x = 2100+6x
(20-6)x = 2100
14x = 2100
x= 2100/14 = 150 m
Speed = x/6 = (350+x)/20 = 150/6 = 500/20 = 25 m/s.
Therefore,
Length of train = 150 m
Speed of train = 25 m/s
Answer:
f(g(x)) = 
Step-by-step explanation:
If f(x) = x + 7 and g(x)=1/x
f(g(x)), plug in g(x) in f(x)
g(x) = 1/x
first we plug in 1/x for g(x)
f(g(x)) = 
Plug in 1/x for x in f(x)
f(x) = x + 7
f(g(x)) = =
<span>The horizontal axis in the coordinate plane is called the x-axis. The vertical axis is called the y-axis. The point at which the two axes intersect is called the origin. The origin is at 0 on the x-axis and 0 on the y-<span>axis</span></span>
