Resolva cada equação seguinte e marque a opção correta* x = - 7/2 = - 3,5 x = 1 k = 133 x = - 2 x = 7 x = 2 x = 10 x = 9/2 = 4,5

-2x + 9 = 0

x/ 2 + 3 = 8

x - 8 = - 3x

3 + 2x - 4 = 13

k/7 = 19

7x + 8 = 3x

2x + 7 =0

- 3x + 1 = -2

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
