From a train station, one train heads north, and another heads east. Some time later, the northbound train has traveled 32 kilometers, and the eastbound train has traveled 24 kilometers. The two trains, measured in a straight line, are kilometers apart.​

Step-by-step explanation:

the eastbound train had travelled 12 miles

Explanation: using Pythagoras theorem, we know that

X^2 = a^2 + b^2

Where ^ stands for raised to power.

Let

a stand for the train going towards North and

b stands for the train going towards east.

X stands for the total distance between train a and b = 20 miles.

By Pythagoras rule

X^2 = a^2 + b^2

20^2 = 16^2 + b^2

400 = 256 + b^2 so that

b^2 = 400 - 256 = 144

b = √144

b = 12 miles.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
