Well you should set up a proportion.

5lbs. 1lbs.

$5.50. $x

You then do 5.5 times 1 then divide that by 5 giving you $1.10.

.Q. The tangent to the curve y=6 ?(x) on the element (4,12) meets the axes at A and B. instruct that the gap AB may well be written in the form { ok?(13) } and state the fee of ok. Ans : Equation of the Curve : y=6 ?(x) factors Given : (x1,y1) = (4,12) Slope of the Tangent (m) = dy/dx = d{6 ?(x)} / dx = 6 * d{?(x)} / dx = 6*{a million/ [2?(x)] } = (3/?(x)) = (3/?(4)) = 3/2 (4 is a element on the line) prepare : Equation of the Tangent : (y-y1) = x (x-x1) exchange the values : => (y-12) = {3/2}*(x-4) => 2*(y-12) = 3*(x-4) => 3x-2y = -24+12 => 3x-2y + 12 = 0 Equation of the Tangent : 3x-2y + 12 = 0 As Given A and B meets the axes : So anticipate : permit the criteria Be A(x,0) and B(0,y) confirm element A(x,0) : y = 0 hence : 3x-2y + 12 = 0 => 3x-2(0) + 12 = 0 => x = -4 element : A(-4,0) confirm element B(0,y) : x = 0 hence : 3x-2y + 12 = 0 => 3(0)-2y + 12 = 0 => y = 6 element : B(0,6) element Given : A(-4,0) and B(0,6) prepare : Distance formulation (AB) :D = ?{(x2-x1)^2+(y2-y1)^2} => D = ?{(0-[-4])^2+(6-0)^2} =>D=?(sixteen+36) =>D = ?(fifty two) =>D=?(13*4) =>D = 2*?(13) Distance formulation (AB) : 2*?(13) unit. -------(a million) Given in the question : ok.13^(a million/2) --------(2) the gap desperate is in this sort .(for this reason proved) fee of ok : 2 {comparing (a million) and(2)} I desire you will enjoy my answer.
