Let y = safe load in pounds and x = length in feet of a horizontal beam. a constant of proportionality k exists such that y=k/x . y varies inversely as x. determine the constant k for a beam with y = 2,000 pounds and x = 15 feet. a. 133.3 b. 3,000 c. 30,000

Option c. 30,000

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form or

Let

y ----> safe load in pounds

x ----> length in feet of a horizontal beam

we have

For

Remember that

substitute

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
