Variations i) Direct Variation ii) Inverse VariationQ. 1: If y varies directly as x, and y = 8 when x=2, find Q. 2: If y `prop` x, and y = 7 when x = 3 find Q. 3: If R `prop` T, and R = 5 when T = 8, find the equation connection R and T. Also find R when T = 64 and T when R = 20. Q. 4: If R `prop` TCant see the pdf file? Click here

^{2}, and R = 8 when T = 3, find R when T = 6. Q. 5: If V `prop` R^{3}, and V = 5 when R = 3, find R when V = 625. Q. 6: If w varies directly as u^{3}and w = 81 when u = 3. Find w when u = 5 Q. 7: if y varies inversely as x and y = 7 when x = 2, find y when x = 126. Q. 8: if `y prop 1/x` and y = 4 when x = 3, find x when y = 24. Q. 9: if `w prop 1/z` and w = 5 when z = 7, find w when `z = 175/4`. Q. 10: if `A prop 1/r^2` and A = 2 when r = 3, find r when A = 72. Q. 11: if `a prop 1/b^2` and a = 3 when b = 4, find a when b = 8. Q. 12: if `V prop 1/r^3` and V = 5 when r = 3, find V when r = 6 and r when V = 320. Q. 13: if `m prop 1/n^3` and m = 2 when n = 4, find m when n = 6 and n when m = 432.Problem loading Video or seeking questions?
