The speed s in m/s of an athlete can be modeled by the
function
s = 9.8 – 9.8e-0.88t
where t is the time (in seconds) after the
athlete starts running. Graph this model and use the graph to
estimate the speed of the athlete 2 seconds after his launch.
Round your answer to the nearest whole m/s.
speed m/s

Answer:

Step-by-step explanation: The equation is s = 9.8 – 9.8e-0.88t and we need to find the speed if t or time = 2 so to solve this equation algebraically you would;

[tex]s = 9.8-9.8e-0.88(2)[/tex]

[tex]s = 9.8-9.8e-1.76[/tex]

[tex]s = 8.04-9.8e[/tex]

and after graphing it you would get

[tex]-18.5991619189[/tex]

which after rounding and using absolute value would be

[tex]s=18.6[/tex]
