Evaluate p^2 - r^2 for p = 10, r = -4 and t = 5. 116 92 84

P² - r²

subtitute p =10 and r= -4

10² - (-4)² = 100 - 16 = 84

Ibelieve the total for the tip could be $21.90

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
