GCF is defined as the Greatest Common Factor. It i<span>s the greatest factor that divides two numbers. In order to find the GCF between the 2 numbers given, we need to find their prime factors first. If you have listed it already, the two common numbers are 2 and 5. So, multiply 2 by 5 and we get 10.
Therefore, the correct answer for this would be the last option, 10. Hope this answer helps.</span>

Answer:
The equation for height is
Step-by-step explanation:
we are given
An iron ball is bobbing up and down on the end of a spring
So, height function must be trigonometric in nature
So, we can use formula
now, we can find A , B and D
Calculation of A:
maximum height 46 inch
minimum height =18 inch
so,
Calculation of B:
It takes the ball 2 seconds to go from its maximum height to its minimum height
So, half of time period is 2 sec
now, we can use period formula
we can find B
Calculation of D:
Max=46
min=18
now, we can plug these values into formula
and we get
Answer:
The speed of a wave depends on the characteristics of the medium. For example, in the case of a guitar, the strings vibrate to produce the sound. The speed of the waves on the strings, and the wavelength, determine the frequency of the sound produced. The strings on a guitar have different thickness but may be made of similar material. They have different linear densities, where the linear density is defined as the mass per length,
μ
=
mass of string
length of string
=
m
l
.
In this chapter, we consider only string with a constant linear density. If the linear density is constant, then the mass
(
Δ
m
)
of a small length of string
(
Δ
x
)
is
Δ

=

For example, if the string has a length of 2.00 m and a mass of 0.06 kg, then the linear density is
μ

If a 1.00-mm section is cut from the string, the mass of the 1.00-mm length is

The guitar also has a method to change the tension of the strings. The tension of the strings is adjusted by turning spindles, called the tuning pegs, around which the strings are wrapped. For the guitar, the linear density of the string and the tension in the string determine the speed of the waves in the string and the frequency of the sound produced is proportional to the wave speed.

Answer:
Step-by-step explanation:
Given: The anchor for the wire is 93 m away from the base of the turbine.
It connects to the turbine 236 m above the ground.
Let x be the angle of elevation for the guy wire
