Use polar coordinates to find the limit. [If (r, θ) are polar coordinates of the point (x, y) with r ≥ 0, note that r → 0+ as (x, y) → (0, 0).] (If an answer does not exist, enter DNE. Do this on paper. Your instructor may ask you to turn in this work.) lim_(\(x text(,) y\) -> \(0 text(,) 0\)) (x^6 + y^3)/(x^2 + y^2)

For f(x)=2x+1 and g(x)= x^2 -7, find (f•g)(x)

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126
