In this question , it is given that a weather balloon is launched from a height of 475 feet above sea level. the balloon rises at a constant rate of 85 feet per minute.
Here we use the slope intercept form, which is
[tex] y = mx+b [/tex]
Where, y is the height h, x is the time, t. And m represents slope, which is 85.
b represents the initial height , which is 475 feet.
On substituting these values, we will get
[tex] h = 85t+475 [/tex]
And at t = 16 minutes, we will get
[tex] h = 85(16) +475 = 1835 feet [/tex]
