2x+ 1 = 3x - 1 ;
1 + 1 = 3x - 2x ;
2 = x ;
x = 2 ;
Then, y = 2x2 + 1 = 5 ;
The equation which models the distance (d) of the weight from its equilibrium after time (t) is equal to d = -9cos(2π/3)t.
<h3>What is the period of a cosine function?</h3>
The period of a cosine function simply means the total length (distance) of the interval of values on the x-axis over which a graph lies and it's repeated.
Since the weight attached is at its lowest point at time (t = 0), therefore, the amplitude of equation will be negative nine (-9)
For the angular velocity at time period (t = 3s), we have:
ω = 2π/T
ω = 2π/3
Mathematically, the standard equation of a cosine function is given by:
y = Acos(ω)t
Substituting the given parameters into the formula, we have;
d = -9cos(2π/3)t.

Answer:
your answer is
<h2>a traepoizd </h2>
Step-by-step explanation:
<em><u>reason</u></em><em><u> </u></em>----
1 <em><u>parallelogram</u></em><em><u> </u></em>
- it is opposite side quadrilateral
- opposite angle
2 <em>rhombus</em><em> </em>
- four congruence side in rhombus
3 <em><u>traepoizd</u></em><em><u> </u></em>
- one pair of congruent sides that were not parallel. It also had one pair of parallel lines.
4 <em><u>kite</u></em><em><u> </u></em>
- two pair of quadrilateral adjacent

No I do not think that 12/60 and 16/40 are equivalent because onec you reduce both of the fractions it does not equal.
