for the simple harmonic motion equation d = 9cos(pi/2)(t), what is the maximum displacement from the equilibrium position ?
belka [17]

Answer:

The maximum displacement from the equilibrium position is 9

Step-by-step explanation:

We are given

equation for the simple harmonic motion equation

y=9cos(\frac{\pi}{2}t)

we can use trig formula

y=Acos(Bt)

The maximum value of this equation is always A

So, firstly, we will compare and find A

A=9

so,

The maximum displacement from the equilibrium position is 9

Which pair of undefined terms is used to define a Ray?
REY [17]

Answer:

The undefined terms which are used to define a ray is:

Point and a line.

Step-by-step explanation:

The undefined terms in coordinate geometry are:

Line, Points and Plane.

since a line do not have any length, Point has a location but no size.

A line has no width and it extends infinitely and is one dimensional.

and a plane extends infinitely in both the dimensions.

<em>Ray:</em>

<em>A ray is part of a line, has one fixed endpoint, and extends infinitely along the line from the endpoint.</em>

Hence, the undefined terms which are used to define a ray is:

Point and a line.

 Simplify. (8(2x^3 y^5 )^3)/((4x^4 y^6 )^4 ) Show your work for each step.
omeli [17]
1)
     8(2^3 x^9y^15)
= ----------------------
    4^4 x^16 y^24

      x^9 y^15
= -------------------
    4 x^16 y^24

             1
= -------------------
    4 x^7 y^9

2)

2^(6x - 12) = (2^-5)^(3x+12)
2^(6x - 12) = 2^(-15x-60)
6x - 12 = -15x - 60 
21x = -48
    x = -48/21
    x = -16/7

The volume of a cube is 1953.1 25 cm³ find the length of the side round your answer to the nearest 10th
34kurt

Answer:

s = ∛( 1953.125 cm³ ) = 12.5 cm

Step-by-step explanation:

The volume of a cube is V = s³, where s represents the length of one edge.

Here, V = s³ = 1953.125 cm³, and we need to solve for s.  Do this by taking the cube root of both sides:

s = ∛( 1953.125 cm³ ) = 12.5 cm
