In Problems 40–44, find the linear, (x, y), and quadratic, (x, y), Taylor polynomials valid near (1,0). Compare the values of the approximations (0.9,0.2) and (0.9,0.2) with the exact value of the function (0.9,0.2). 40. (x, y) =√x + 2y

Adifferent website gives the cost for the first train as £56.88 and the second train as £20.11 with a £9.50 charge for cycle storage for the whole trip. how much would the journey cost you?

Which ordered pair is a solution to the system of linear equations? 2x + 3y= 6 –3x + 5y = 10

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
