Exercise 10.2

find the equation of the line which satisfy the given condition: The owner of a milk store finds that, he can sell 980 litres of milk each week at Rs. 14/litre and 1220 litres of milk each week at Rs. 16/litre. Assuming a linear relationship between selling price and demand, how many litres could he sell weekly at Rs. 17/litre?

Accepting the connection between selling cost and request is direct.   Allow us to accept selling cost per liter along X-pivot and request along Y-hub, we have two focuses \[\left(...

find the equation of the line which satisfy the given condition: The length L (in centimetre) of a copper rod is a linear function of its Celsius temperature C. In an experiment, if L = 124.942 when C = 20 and L= 125.134 when C = 110, express L in terms of C.

 Allow us to expect 'L' along X axis and 'C' along Y axis, we have two focuses \[\left( \mathbf{124}.\mathbf{942},\text{ }\mathbf{20} \right)\text{ }\mathbf{and}\text{ }\left(...

find the equation of the line which satisfy the given condition: Find equation of the line through the point (0, 2) making an angle 2π/3 with the positive x-axis. Also, find the equation of line parallel to it and crossing the y-axis at a distance of 2 units below the origin.

 Given:   \[\mathbf{Point}\text{ }\left( \mathbf{0},\text{ }\mathbf{2} \right)\] and \[\mathbf{\theta }\text{ }=\text{ }\mathbf{2\pi }/\mathbf{3}\] We realize that \[\mathbf{m}\text{ }=\text{...
