At a temperature of t degrees​ Fahrenheit, sound travels s feet per​ second, where s equals 21.9 StartRoot 5 t plus 2457 EndRoot
mafiozo [28]

Answer:

32.63 F

Step-by-step explanation:

The function:

s = 21.9 \; \sqrt{ 5 t + 2457 }

represents sound travels s at feet per​ second, where t is the temperature at Fahrenheit degrees​.

We know that sound traveled at a rate of 1121 ​ft/sec. To find the temperature we need to replace with s value and isolate t for the above function.

1121 = 21.9 \; \sqrt{ 5 t + 2457 }

\frac{1121}{21.9} = \sqrt{ 5 t + 2457 }

51.19^2 = 5 t + 2457

2620.13 - 2457 = 5 t

\frac{163.13}{5} = t

32.63 \; F= t
