a. 0
b. 2
c. 3
d. 5

Look at the pattern here.
1 = 1 x 1
1 + 3 = 2 x 2
1 + 3 + 5 = 3 x 3
1 + 3 + 5 + 7 = 4 x 4

Which of the following options equal to?

1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 =

a. 6 x 6
b. 10 x 10

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
