Concept explainers
To find: The constant of variation and use it to write an equation, if y varies directly as the square root of x and inversely as z andy = 7.2 when x = 0.3 and z = 4, find y when
x = 1 and z = 40. Then solve the equation.
Answer to Problem 58SGA
Explanation of Solution
Given information: If y varies directly as the square root of x and inversely as z and y = 7.2 when x = 0.3 and z = 4, find y when x = 1 and z = 40
Calculation:
As y varies directly as the square root ofxand inversely as zgives you,
And:
This gives us:
Finally:
Thus,
