Show the order of evaluation of the following expressions by parenthesizing all subexpressions and placing a superscript on the )to indicate order. For example, for the expression a + b * c + d the order of evaluation would be represented as ((a + (b * c)1)2 + d)3 a. a * b - 1 + c b. a * (b - 1) / c mod d c. (a - b) / c & (d * e / a - 3) d. -a or c = d and e e. a > b xor c or d <= 17 f. -a + b

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
