variation and graphs

Suppose z varies directly as the fourth power of w. if z = 80 when w = 2, find z when w = 3. When w = 3, z = 405.
Consider the equation s = 5d^2. How does the value of s change if d is doubled? Multiplied by 4.
write the variation equation m = kn^5 in words. m varies directly as n to the fifth power.
Complete with "inversely," "directly," or "neither." the time it takes to run a given distance varies ____ as the rate. inversely.
What is a inverse variation function? A function with a formula of th form y = k/x^n, with k not equal to 0 and n > 0.
given the equation y = k/x^3, suppose that y = 4 hen x = 3. find y when x = 5. y = 108/125
consider y = 6/x. Find the rate of change from x = 1 to x = 2. -3.
