Step-by-step explanation:
h(n)=2n-1; find h(3y)
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
m
=
μ
Δ
x
.
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
=
0.06
kg
2.00
m
=
0.03
kg
m
.
If a 1.00-mm section is cut from the string, the mass of the 1.00-mm length is
Δ

=
(
0.03

)
0.001
m

kg
.
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.

y = 6x + 11
2х - Зу = 7
9514 1404 393
Answer:
(x, y) = (-2.5, -4)
Step-by-step explanation:
Since you are given an expression for y, it is convenient to substitute that into the second equation.
2x -3(6x +11) = 7
2x -18x -33 = 7
-16x = 40 . . . . . . add 33
x = -40/16 = -2.5
Using the equation for y, we find ...
y = 6(-2.5) +11 = -15 +11 = -4
The solution is (x, y) = (-2.5, -4).

STEP2
WRITE 28y AS A SUM
STEP3
FACTOR OUT 3x2 + 24xy
SO IT'S
[tex]y \times (3x \times (x + 8y) + 4xy + 32y {}^{2} )[/tex]
STEP4
FACTOR OUT 4xy + 32y2
SO IT'S
[tex]y \times (3x \times (x + 8y) + 4y \times (x + 8y) \: )[/tex]
STEP5
FACTOR OUT (3x × ( x + 8y ) + 4y × ( x + 8y ) )
SO THE ANSWER IS

For those who are good with equations....(unlike me when it comes to this)
Answer:
a = 5
Step-by-step explanation:
When the coefficients of the variables are equal with different constants, then you will get an equation which is never true.
For this particular equation, when a on the right side has a coefficient of 5, you will get the equation: 4(a - 2) + a = 5a - 4.
When you distribute the factors in the parenthesis and add the like terms of a together, 4(a - 2) + a will become 5a - 8. This is because 4(a - 2) + a = 4(a) + 4(-2) + a = 4a - 8 + a = 5a - 8.
Now when you simplify 5a - 8 = 5a - 4 by subtracting 5a from both sides, you will get an equation with unlike constants. For instance 1 = 0.
Now:
5a - 8 = 5a - 4
-5a -5a
-8 = -4
This is never true, so therefore, there is no solution.
Answer:
It is 5

What is the equation of the line that has a slope of -6/5 and goes through the point (5, -4)?
Answer:
Step-by-step explanation:
Given
slope =6/5
point =(5, -4)
So
the equation of the line =
(y-y1)=m(x-x1)
Where X1=5,y1=-4,m=6/5
Put the values
(Y+4)=6/5(x-5)
5(Y+4)=6(x-5)
5y+20=6x-30
5y-6x=-30-20
-6x+5y=-50
6x-5y=50.
So the equation of the line is 6x-5y=50.
