Answer:

bottom right

Step-by-step explanation:

Basically we have to rewrite C = 2πr so that r is the subject. To do so, we divide the entire equation by 2π which gives us r = C / 2π.

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.

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

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

$51.19^2 = 5 t + 2457$

$2620.13 - 2457 = 5 t$

$\frac{163.13}{5} = t$

$32.63 \; F= t$
