Calculate the speed of a wave with the frequency of 100 hz and wavelength of 250 m, please.
masya89 [10]

Answer:

25000m/s

Step-by-step explanation:

The following formula is used to calculate the speed or velocity of a wave.

V = f * w

Where V is the velocity (m/s)

f is the frequency (hz)

w is the wavelength (m)

First, determine the frequency.

Calculate the frequency of the wave.

Next, determine the wavelength.

Calculate the wavelength of the wave.

Finally, calculate the wave speed.

Using the formula above, calculate the wave speed.

The volume of a cylinder is 770 cm. It's height is 5 cm. Find its approximate radius.
Alinara [238K]

Hey there,

The equation for the volume of a cylinder is V = πr²h.

The first step into finding the radius is to plug in what you already know into the equation:

  • 770 = πr²5

We divide both sides by 5:

  • 154 = πr²

Now we divide both sides by π:

  • 49.0197224723 = r²

Finally we just do the square root of 49.0197224723:

  • 7.0014086063 = r

The radius therefore would be about 7cm.

Hope I helped,

Amna

The cost for the raw materials of marble countertops, can be represented by the function , where is the area of the countertops.
Lady_Fox [76]

Answer:

m(c(a)) = 4.8875a

Step-by-step explanation:

The missing parameters are:

c(a) = 4.25a --- Cost of marble countertops

m(c) = 1.15c --- Cost of retail markup

Required

The cost of marked up price

This implies that we calculate m(c(a))

We have:

c(a) = 4.25a

m(c) = 1.15c

m(c) = 1.15c can be written as:

m(c(a)) = 1.15*c(a)

Substitute: c(a) = 4.25a

m(c(a)) = 1.15*4.25a

m(c(a)) = 4.8875a

Hence, the cost of marked up price is: m(c(a)) = 4.8875a
