serious [3.7K]

Answer: $2549

<u>Step-by-step explanation:</u>

A = P(1 + r)ˣ  ; where P is Principal, r is rate, and x is time

Given:

  • P = 1509
  • r = 6%  = 0.06
  • x = 9

A = 1509(1 + 0.06)⁹

   = 1509(1.06)⁹

   = 1509(1.6895)

   = 2549.42

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
