The speed of sound is 1088 feet per second at sea level at 32° f. write and solve an equation to find the distance sound travels in 8 seconds under these conditions.

It is given in the question that,

The speed of sound is 1088 feet per second at sea level at 32° f.

It means , in one second, sound travels a distance of 1088 feet.

And we have to find the distance travelled by sound after 8 seconds.

Therefore, after 8 seconds, the sound travels

the answer is d

step-by-step explanation:

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
