1.A wave has a frequency of Hz and a wavelength of 30m. What's it's speed? 2. If the speed of a wave is 140m/s and it's frequency in 3 Hz, what is it's wavelength?

3. An ocean wave has a length of 15 meters. A wave passes a fixed location every 4 seconds. What is the speed of the wave?

4.A sound wave in air has a frequency of 260 Hz and travels at a speed of 330 m/s. What is the wavelength of this wave?

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
