Abe wants to sell artisanal drinks during the holidays. He produces 160 litres of the drink and sells a part of it at 10% profit. He sells the rest of the drink at 6% profit.What quantity of the drink did he sell at 10% profit if he gained 9% profit on the entire 160 litres? |
|
Answer» ong>Solution :- Let us ASSUME that, abe sell X litre of drink at 10% profit . A/q, → 1.1x + 1.06(160 - x) = 1.09 * 160 → 1.1x + 1.06*160 - 1.06x = 1.09 * 160 → 1.1x - 1.06x = 160(1.09 - 1.06) → 0.04x = 160 * 0.03 → 4x = 480 → x = 120 litres (Ans.)

(ii) In the graph as shown in the Fig., the change in y when x changes from 0 to 2 is(a) 4(6) - 2(c) - 3(d) 262.11-0 1 2 3 4 5 6 |
|
Answer» ong>Answer: tangent line to f(x)=1/x at x=2 provides a GOOD approximation to f for x near 2 . (b) At x=2.1 , the value of y on the tangent line to f(x)=1/x is 0.475 . The actual value of f(2.1) is 1/2.1 , which is approximately 0.47619 . A tangent line to the graph of a function at a point (\(a,f(a)\)) is the line that secant lines through (\(a,f(a)\)) approach as they are taken through POINTS on the function with \(x\)-values that approach \(a\); the slope of the tangent line to a graph at \(a\) measures the RATE of change of the function at \(a\) In general, for a differentiable function f , the equation of the tangent line to f at x=a can be used to approximate f(x) for x near a . Therefore, we can write f(x)≈f(a)+f′(a)(x−a) for x near a . We call the LINEAR function L(x)=f(a)+f′(a)(x−a)(4.2.1) the linear approximation, or tangent line approximation, of f at x=a . This function L is also known as the linearization of f at x=a. To show how useful the linear approximation can be, we LOOK at how to find the linear approximation for f(x)=x−−√ at x=9. |
