State Government wants to connect the state road to the national highway from a town. There are 3 possible locations in the town A,B and C to connect to the National Highway whose locations are given by coordinates (3,8)(3,8),(5,7)(5,7),(6,9)(6,9) . The National Highway connects the 2 points (2,1)(2,1),(10,7)(10,7) and You, being the contractor, have the freedom to select any one of the 3 possible locations in the town.
Hint Always select the shortest path to construct the road.

8. A bird is flying along the straight line 2�−6�=442y−6x=44. In the same plane, an aeroplane starts to fly in a straight line and passes through the point (4,12)(4,12). Consider the point where aeroplane starts to fly as origin. If the bird and plane collides then enter the answer as 1 and if not then 0. Note: Bird and aeroplane can be considered to be of negligible size.

A fitness trainer is analyzing the weight loss progress of his best client over a period of 6 months, to use it as for marketing. He recorded the weight of the client at the beginning and end of each month. Using straight line fitting, he came up with an equation �=−8�+98W=−8t+98, where W = Weight in Kg, t= time in months.
Now you want to check weather this equation is correct or not so you collected the data from the gym, the data is given in table below.
11. Equation that fitness trainer came up with �=−8�+98W=−8t+98 is well fitted to data. (Equation is said to be well fitted to data if the SSE is less than 5)

The equation used to measure the ��Cd (discharge coefficient) of the venturimeter value in the lab is:
�=��1−�42�ΔℎQ=1−β4cd2gΔh
��– discharge coefficientcd– discharge coefficient
�– ��β– Dd
A1– Pipe section
A2– Restriction area
Δℎ– head lossesΔh– head losses
Q– flow rate
Ramesh plotted the graph between Q on the y-axis and ΔℎΔh on the x-axis and claimed that ��1−�42�1−β4cd2g is the slope of the obtained straight line.
Suresh plotted the graph between ΔℎΔh on the y-axis and Q on the x-axis and claimed that 1−�4��2�cd2g1−β4 is the slope of the straight line.
Who is/are actually correct?
