Answer:

Wavelength of sound wave corresponding to 20 Hz frequency will be 17.95 m

Explanation:

We have given that range of human hearing extends from 20 Hz and 20000 Hz

Velocity of sound wave is given 359 m /sec

We have to find the wavelength of the sound wave corresponding to 20 Hz

We know that velocity of sound wave is given by v=\lambda f, here v is velocity \lambda is wavelength and f is frequency

So 359=\lambda \times 20

\lambda =17.95m

So wavelength of the sound wave corresponding to 20 Hz frequency will be 17.95 m

Find the Maclaurin series for f(x) using the definition of a Maclaurin series. [Assume that f has a power series expansion. Do n
jenyasd209 [6]

The statement about pointwise convergence follows because C is a complete metric space. If fn → f uniformly on S, then |fn(z) − fm(z)| ≤ |fn(z) − f(z)| + |f(z) − fm(z)|, hence {fn} is uniformly Cauchy. Conversely, if {fn} is uniformly Cauchy, it is pointwise Cauchy and therefore converges pointwise to a limit function f. If |fn(z)−fm(z)| ≤ ε for all n,m ≥ N and all z ∈ S, let m → ∞ to show that |fn(z)−f(z)|≤εforn≥N andallz∈S. Thusfn →f uniformlyonS.

2. This is immediate from (2.2.7).

3. We have f′(x) = (2/x3)e−1/x2 for x ̸= 0, and f′(0) = limh→0(1/h)e−1/h2 = 0. Since f(n)(x) is of the form pn(1/x)e−1/x2 for x ̸= 0, where pn is a polynomial, an induction argument shows that f(n)(0) = 0 for all n. If g is analytic on D(0,r) and g = f on (−r,r), then by (2.2.16), g(z) =

Increasing the speed of your vehicle influences the risk of being involved in a traffic collision because it _________.
anzhelika [568]

Answer:

Explanation:

When you're driving and you increase the speed of your car, it influences the chances of being involved in a traffic collision because it reduces the amount of time to adjust before a collision happens, and increasing the speed also contribute to the intensity of collision. Hence, making it difficult for anyone to survive.
