The equation below represents a candle that is burning where y represents the height of the candle in inches and x represents the time in hours. y=6−12x What does the x-intercept represent in context? Question 4 options: the starting height of the candle is 12 inches the starting height of the candle is 6 inches it will take the candle 12 hours to completely burn away it will take the candle 6 hours to completely burn away

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
