5 pieces. 4.65÷0.85=5. so u divide and ur answer is 5
Answer:
An object moving along the x-axis is said to exhibit simple harmonic motion if its position as a function of time varies as
x(t) = x0 + A cos(ωt + φ).
The object oscillates about the equilibrium position x0. If we choose the origin of our coordinate system such that x0 = 0, then the displacement x from the equilibrium position as a function of time is given by
x(t) = A cos(ωt + φ).
A is the amplitude of the oscillation, i.e. the maximum displacement of the object from equilibrium, either in the positive or negative x-direction. Simple harmonic motion is repetitive. The period T is the time it takes the object to complete one oscillation and return to the starting position. The angular frequency ω is given by ω = 2π/T. The angular frequency is measured in radians per second. The inverse of the period is the frequency f = 1/T. The frequency f = 1/T = ω/2π of the motion gives the number of complete oscillations per unit time. It is measured in units of Hertz, (1 Hz = 1/s).
The velocity of the object as a function of time is given by
v(t) = dx(t)/dt = -ω A sin(ωt + φ),
and the acceleration is given by
a(t) = dv(t)/dt = -ω2A cos(ωt + φ) = -ω2x.
Answer:
Step-by-step explanation:
the solution to the system
= find the intersection of two lines
method( one )
solve the equations ( find(x , y) )
( 1 ) y = -x +3
( 2 ) y = x - 3
now , we let ( 1 ) + (2 )
we have 2y =0 ,thus y = 0
from ( 1 ) y = - x +3 , we know y = 0 ,
we rewrite ( 1 ) as 0 = -x + 3,thus x = 3
method( two)
see the intersection point of two lines
so the ans is B.(3 , 0)
Answer:
tbh that doesnt make sense the easiest way to et the first one is to do 955 divided by 90.
Step-by-step explanation:
A graph for the data (time and distance) shown in the given table is plotted in the image attached below.
<h3>What is a graph?</h3>
A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
<h3>What is a linear function?</h3>
A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
This ultimately implies that, the data of a linear graph are directly proportional and as such as the value on the x-axis increases or decreases, the values on the y-axis also increases or decreases.
In this exercise, you're required to plot a graph for the data (time and distance) that are recorded for an object that is starting from rest.
By critically observing the graph (see attachment) which models the data in the given table, we can infer and logically deduce that the linear function is given by:
y = 67.814x
