Explanation Given: The number of people N (measured in thousands) who participate in boating can be described by the function: N ( x ) = 1.99 x 2 − 6.76 x + 1098.4 where x is the mean income (measured in thousands) and x ≥ 10 . Calculation: Consider the provided inequality, N ( x ) = 1.99 x 2 − 6.76 x + 1098.4 The values of N ( x ) at different x are: N ( 10 ) = 1229.8 N ( 30 ) = 2686.6 N ( 50 ) = 5735.4 And, N ( 70 ) = 10376.2 N ( 90 ) = 16609 So, the coordinates are ( 10 , 1229

You are given a plane Π in R3 defined by two vectors, p1 and p2, and a subspace W in R3 spanned by twovectors, w1 and w2. Your task is to project the plane Π onto the subspace W.First, answer the question of what the projection matrix is that projects onto the subspace W and how toapply it to find the desired projection. Second, approach the task in a different way by using the Gram-Schmidtmethod to find an orthonormal basis for subspace W, before then using the resulting basis vectors for theprojection. Last, compare the results obtained from both methods
