A severe storm has moved into your area and the weather sirens have begun to go off. The frequency of the sirens ranges between 200 HZ and 2,000 Hz. What is the range of wavelength emitted sounds? (the velocity of sound in air is 340 m/s)
017 to
0.59 to 5.9 m
0.59 to 1.7 m
0.17 to 5.9 m

$450 i think. hope this ☺

i don’t see a picture

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
