Answer:
[(cosθ-1)^2]/(sinθ)^2
Step-by-step explanation:
(cotθ-cscθ)^2
(cotθ)^2-<em>2cscθcotθ</em>+<u>(cscθ)^2</u>
(cosθ/sinθ)^2-2<em>(cosθ/(sinθ)^2) +</em><u>1/(sinθ)^2</u>
All have same denominator, (sinθ)2, add/subtract
((cosθ)^2-2cosθ+1)/(sinθ)^2
Factor the top
[(cosθ-1)^2]/(sinθ)^2
Answer: 5.824 m / min
Step-by-step explanation:
Change in position = -2.1m to -38.6m
Distance = |-38.6 m - (-2.1m) |
=|-36.5| m
= 36.5 m
Time = 

The average change in Michelle's position each minute = 

Hence, the average change in Michelle's position each minute = 5.824 m / min
The motion of the mass as it moves on the bottom of the spring is a
repetitive motion.
Reasons:
The general form of the equation of the simple harmonic motion of the
mass is <em>d</em> = a·sin(ω·t)
Where;
d = The distance of the mass from the rest position
a = The maximum displacement of the mass from the equilibrium position = 6 cm
ω = The frequency of rotation
t = The time of motion
ω = The frequency of rotation

Where;
T = The time to complete one cycle (the period of oscillation) = 4 seconds

Combining the above values gives the modelling equation as follows;

Answer:
y= -7
Step-by-step explanation:
I'm not sure if this is what you are looking for but here you go!
If the equation is set equal to zero.
2+(5+y)=0 This is the original expression, we need to find the value for y.
5+y= -2 We move the two to the right to remove it from the left side of
the equation.
y= -7 We repeat the same thing as we did in the last step, except
with the value 5. This then gives us our y-value, which is -7.
I hope this helps!
