The equation for the height exists h = 31 sin((8π)t + π/2) + 35.
How can the height of the wristband be modeled?The model for the height can be emanated from the general formula of the sine function, then
y = A sin(Bt - C) + D
Maximum point = 70 - 4 = 66 at t = 0
Minimum point = 4
Amplitude, A = (66 - 4) ÷ 2 = 31
D = 4 + 31 = 35
At t = 0, we have;
66 = 31 × sin(B × 0 - C) + 35
31 = 31 × sin(- C)
sin(- C) = 1
C = -π/2
1 minute = 60 seconds
1 second = 1 minute/60
15 seconds = (15/60) minutes
Period = 15 seconds = 15/60 minutes
Period = 2π/B
Therefore, 15/60 = 2π/B
1/4 = 2π/B
B = 2π/(1/4) = 8π
y = Height of the function
Let h denote the height of the wristband.
The equation for the height exists h = 31 sin((8π)t + π/2) + 35.

By using the concept of linear progression and some algebraic handling, we conclude that Joe will earn an amount of $ 31 700 in the 14th year.
How to determine the future income of a worker
According to the statement, we have a case of linear progression as income increases at same rate in time. Linear progressions are described by this formula:
c' = c + r · t (1)
Where:
c - Initial amountc' - Current amountr - Increase ratet - TimeFirst, we calculate the increase rate:
r = (29 600 - 22 600)/10
r = 700
Now we proceed to find when Joe will earn an annual income of $ 31 700:
31 700 = 22 600 + 700 · t
t = 13

By trigonometric solution of triangles we conclude that the actor is staying at the balcony of the second floor.
In which floor of the hotel does an actor stay in a balcony?
This problem presents an application of trigonometric resolution of triangles to find the floor where the actor is in terms of the height of the building. Based on the picture seen in the image, we find that all known dimensions of the triangle , three angles and a side, are:
A = 140°, B = 30°, C = 10°, p = 6 m
First, we must find the length of side AP by law of sines:
b / sin 30° = 6 / sin 10°
b = 6 × sin 30° / sin 10°
b ≈ 17.276 m
Second, the height of the building is found by trigonometric functions:
h = (17.276 m) · sin 40°
h ≈ 11.105 m
Therefore, the floor where the actor stays is:
3.8 + 3 · n = 11.105
3 · n = 7.305
n = 2.435
n = 2
By trigonometric solution of triangles we conclude that the actor is staying at the balcony of the second floor.

The graphs of f(x) and g(x) are transformed function from the function y = x^2 and the solution of the set of inequalities is (±1.581, -0.5)
How to modify the graphsThe complete question is in the attached image (the first graph)
From the graph, we have:
f(x) = x^2 - 3 and g(x) = -x^2 + 2
To derive y ≤ x^2 - 3, we simply change the equality sign in the function f(x) to less than or equal to.
To derive y > -x^2 + 2, we simply change the equality sign in the function g(x) to greater than
How to identify the solution setThe inequalities of the graphs become
y ≤ x^2 - 3 and y > -x^2 + 2
From the graph of the above inequalities (see attachment 2), we can see that the curves of the inequalities intersect at (±1.581, -0.5)

Identify the theorem or postulate that is related to the measures of the angles in the pair, and find the unknown angle measures.
m∠3=(50x−100)∘, m∠5=(25x+25)∘
Using the corresponding angles postulate:
m∠3 = 150°
m∠5 = 150°
What is the Corresponding Angles Postulate?According to the corresponding angles postulate, corresponding angles, ∠3 and ∠5 are congruent to each other.
Thus, we would have the following equation:
m∠3 = m∠5
Plug in the values
50x - 100 = 25x + 25
50x - 25x = 100 + 25
25x = 125
x = 125/25
x = 5
m∠3 = 50x − 100 = 50(5) − 100 = 150°
m∠5 = 25x + 25 = 25(5) + 25 = 150°

c) Sketch a graph to illustrate your answers.
The maximum height of the object is 15.4 m and occurs at 0.295 sec. The object touches ground at 2.06 seconds
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
A ball is thrown upward from the top of a building 15 meters high, at a velocity of 2.8m/sec. Hence:
s = -4.9t² + 2.8t + 15
The maximum height is at s'(t) = 0, hence:
-9.8t + 2.8 = 0
t = 0.295 s
s = -4.9(0.295)² + 2.8(0.295) + 15 = 15.4 m
The object reaches ground when s = 0, hence:
0 = -4.9t² + 2.8t + 15
t = 2.06 seconds
