Question 1069185: If y is directly proportional to the five-halves power of x, and y has the value 58.6 when x is 19.4:
Round your answers to 3 significant digits.
(a) Find the constant of proportionality, k.
k =
(b) Write the equation y equals f left-parenthesis x right-parenthesis using k from a.
y =
(c) Find y when x = 26.2.
y =
(d) Find x when y = 83.6.
x = Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! y=kx^(5/2)
58.6=k*19.4^(5/2)
k=58.6/19.4^(5/2)=0.0354
-----------
y=(0.0354)x^(5/2)
when x=26.2, y=124.38; 3 sig digits 124
when x=83.6, y=2470.57 3 sig digits 2470
