The amount of time in seconds it takes for a swimmer to hear a single, hand-held, starting signal is given by the formula below, where (x,y) is the location of the starter (in meters), (0.p) is the location of the swimmer (in meters), and C is the air temperature (in degrees Celsius). Assume that the starter is located at the point (4,-2). Answer parts a and b below. √√x² + (y-p)² t(x,y.p.C)= 331.45+0.6C a. Calculate t(4, -2,30,20) and t(4, -2,20,20). Could the difference in time change the outcome of a race? t(4, -2,30,20) = (Round to five decimal places as needed.) Ay p Swimmer Starter (4,-2)

Transcribed Image Text:The amount of time in seconds it takes for a swimmer to hear a single, hand-held, starting signal is given by the formula below, where (x,y) is the location of the
starter (in meters), (0,p) is the location of the swimmer (in meters), and C is the air temperature (in degrees Celsius). Assume that the starter is located at the
point (4,-2). Answer parts a and b below.
t(x,y.p.C) =
√²+(y-p)²
331.45+0.6C
a. Calculate t(4, -2,30,20) and t(4, -2,20,20). Could the difference in time change the outcome of a race?
