Answer:
The slope of your body is -17
Step-by-step explanation:
In order to find slope we have to use this equation:
The two points we are given are (10, 0) and and (0, 170). Let's input these values into our equation
Now let's simplify: = -17
The slope of your body is -17
hence,
65=5(1-3^n)/1-3
( multiply by -2 on both sides )
130=5(1-3^n)
26=1-3^n
27=3^n
from here, you can use lg to solve for n.
lg 27 = lg 3^n
lg 27 = n lg 3
n = lg 27 ÷ lg 3
hence, n = 3
Since the real track has a gauge of 3 feet but the model railroad track has a gauge of 3/4 inches, the scale factor must be 1/4, because you must follow the rule
"true measurement * scale factor = model measurement"
In fact, we have
This implies that the original driving wheels height, 44 inches, must be scaled down to
inches.
