A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is the frequency of a wave that has a period of 40 seconds?

1/40 = 0.025 Hertz

A wave is moving at the rate of 40 cms. Its wavelength is 8 cm. What is the frequency of the wave?

It is 5 Hz.

What is the frequency of wave with time period 0.025 s?

f = 1/t = 1/0.025 = 40 Hz

What is wavelength of 40 hertz?

That would also depends on the speed of the wave. The relationship is: speed = frequency x wavelength.

If a wave has a velocity of 40 meterssecond and a frequency of 120 Hz what is its wavelength in meters?

The speed c = 40 meters per second and the frequency f = 120 Hz. The wavelength lambda = c / f. Lambda = 40 / 120 = 0.3333333333 meters.

What is the frequency of the wave moving at the rate of 40 cms. Its wavelength is 8 cm.?

Divide the speed by the wavelength.

A rectangular wave has a 60 percent duty cycle and a frequency of 50 Mhz how long is the signal low?

First of all there is no definition of retangular wave. Maybe your retangular is my square wave. and the answer is inconclusive unless you specify the 40% level.

How fast is a wave moving if it has a frequency of 10 Hz and there are 4 meters between crests?

10*4 = 40 metres per second

How the 40 meters wave length is equal to 7 mhz frequency?

It seems you are talking about radio waves. The wavelength (40 m) multiplied by the frequency (7 million / second) must equal the speed of light (300 million meters/second). It seems that in this example numbers, either the wavelength or the frequency, or both, are not expressed with a great accuracy. For example, if 40 meters is exact, the frequency would be close to 7.5 MHz.

What is the wavelength of an electromagnetic wave that travels 3 x 10 and has a frequency of 4 x 10?

wavelength=velocity/frequency (v/f). wavelength=(3x10/4x10)=30/40=.75 meters

When the frequency and wavelength are known answerer?

Frequency refers to how many waves pass a fixed point in a unit of time. Frequency is measured in Hertz, or Hz, and one Hertz means a single wave passes a given fixed point in one second. Wavelength refers to the length of an entire wave, so either from crest to crest or trough to trough. If you know how many waves pass a given point in a unit of time, which is frequency, and how long the waves are, which is wavelength, you can find the wave's speed. For example, if a wave has a frequency of 10 Hz, so ten waves pass a given point in a second, and it has a wavelength of four meters, you multiply the frequency by the wavelength to find that the waves are traveling at 40 meters per second.
