G Suppose that we have a quadrature Qn using n+1 function evaluations that approximates the integral Z b a f(x)dx with the error Z b a f(x)dx − Qn(f) = a1 · sin(1/n) + a2 · (sin(1/n))2 + a3 · (sin(1/n))3 + . . . . Using Qn, Q2n and Q4n, perform 2 steps of Richardson’s extrapolation, i. e., write down the formula for the resulting method and express its error in terms of a power of 1/n.

Jessica is a custodian at oracle arena.she waxes 20 m2 of the floor in 3/5 of an hour. jessica waxes the floor at a constant rate.at this rate how many sqaures meters can she wax per hour

What is the missing constant term in the perfect square that starts with x^2 -20x

The data shown in the table below represents the weight, in pounds, of a little girl, recorded each year on her birthday. age (in years) weight (in pounds) 2 32 6 47 7 51 4 40 5 43 3 38 8 60 1 23 part a: create a scatter plot to represent the data shown above. sketch the line of best fit. label at least three specific points on the graph that the line passes through. also include the correct labels on the x-axis and y-axis. part b: algebraically write the equation of the best fit line in slope-intercept form. include all of your calculations in your final answer. part c: use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.
