The change in x from A to B is positive. The line is going up, so the slope cannot be negative

How many times longer is the wavelength of a sound wave with a frequency of 20 waves per second than the wavelength of a sound w
sergejj [24]

The sound wave with a <u>frequency of 20</u> waves/sec is 800 longer than the wavelength of a sound wave with a <u>frequency of 16,000</u> waves/sec

<h3>Calculating wavelength </h3>

From the question, we are to determine how many times longer is the first sound wave compared to the second sound water

Using the formula,

v = fλ

∴ λ = v/f

Where v is the velocity

f is the frequency

and λ is the wavelength

For the first wave

f = 20 waves/sec

Then,

λ₁ = v/20

For the second wave

f = 16,000 waves/sec

λ₂ = v/16000

Then,

The factor by which the first sound wave is longer than the second sound wave is

λ₁/ λ₂ = (v/20) ÷( v/16000)

= (v/20) × 16000/v)

= 16000/20

= 800

Hence, the sound wave with a <u>frequency of 20</u> waves/sec is 800 longer than the wavelength of a sound wave with a <u>frequency of 16,000</u> waves/sec

wlad13 [49]
The future value of the investment in dollars s
V = p + prt
where 
p = principal, dollars
r = annual interest rate (in decimal form)
t = time, years

To determine p, write the formula as follows:
Factorize p out on the right side.
  V = p(1 + rt)
Divide each side b (1 + rt).
  \frac{V}{1+rt}=p

Answer:
p= \frac{V}{1+rt}
