The height of a hot air balloon is tracked as it makes its trip from launch to the landing site. Look at the graph to determine
what is happening at each labeled segment of the graph,
Height
Time
Which label corresponds to the segment showing the balloon descending but not landing?

step-by-step explanation:

the first 5 right here the next 5 i will upload as separate question

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
