A Ferris wheel 80 meters in diameter turns continuously, completing a single rotation once every 8 minutes. You must board the Ferris wheel at its lowest point from a platform located 5 meters above the ground. If you board the Ferris wheel at t=0, write and sketch a sinusoidal function to model your height above the ground after t minutes on the Ferris wheel. How high above the ground will you be after 5 minutes? How many minutes into the ride will it be when you first reach 35 meters above the ground?
Step-by-step explanation:
General form of a sine or cosine wave is:
y = ±A sin((2π/T) t) + B
y = ±A cos((2π/T) t) + B
where A is the amplitude, T is the period, and B is the vertical offset or midline.
The Ferris wheel is 80 meters in diameter or 40 meters in radius.
A = 40
The Ferris wheel turns once every 8 minutes.
T = 8
The lowest point is 5 meters above the ground, so the center of the Ferris wheel is 45 meters above the ground.
B = 45
At t=0, you're at the lowest point, so use -cos.
Therefore, the equation is:
y = -40 cos(2π/8 t) + 45
y = -40 cos(π/4 t) + 45
When t = 5:
y = -40 cos(5π/4) + 45
y = 20√2 + 45
y ≈ 73.3 meters
When y = 35:
35 = -40 cos(π/4 t) + 45
-10 = -40 cos(π/4 t)
1/4 = cos(π/4 t)
π/4 t ≈ 1.318
t ≈ 1.68 minutes

Answer:
Step-by-step explanation:
cos x° = [tex]\frac{27}{30}[/tex] = 0.9 ⇒ x° ≈ 25.8°
The value of x will be 25.8°. Option D is correct. Trigonometric formulas of cos is used in the given formula.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.
From ΔABC it is obtained that;
[tex]\rm cos \theta = \frac{Base}{Hypotenuse} \\\\ os \theta = \frac{B}{H} \\\\ cos \ x^0=\frac{27}{30}\\\\ x^0=25.8^0[/tex]
The value of x will be 25.8°.

Sophia works in a clothing store and earns $40 per day. She earns an extra $5 for each outfit she sells. If Sophia wants to earn at least $70 per day, which inequality shows the minimum number of outfits, n, that she should sell? (5 points) 40 + 5n ≤ 70, so n ≤ 6 40 + 5n ≥ 70, so n ≥ 25 40 + 5n ≤ 70, so n ≤ 25 40 + 5n ≥ 70, so n ≥ 6
Answer:
In order to find this answer, you will need to be able to make an inequality.
Step 1: Sophia makes $40 so start with that. 40
Step 2: Sophia also makes $5 per every outfit that she sells, so add that plus your variable (n). 40+5n
Step 3: Determine if Sophia wants to make more, equal to or more, less, or less than or equal to than what she wants to make per day. 40+5n *draw a greater than or equal to sign.
Step 4: Sophia wants to make more than or equal to what she makes per day. You will need to find what she wants to make more than. In this she wants to make more than or equal to $70.
Equation: 40+5n *greater than or equal to sign* $70
Step-by-step explanation:
Answer:
40 + 5n ≥ 70, so n ≥ 6
Step-by-step explanation:
40 + 5n ≥ 70
5n ≥ 30
n ≥ 6

1. The area of a rectangular garden is 8064 m2.
If the width of the garden is 84 m, what is its length?
Length of the garden:
2. The perimeter of a rectangular window is 288 cm.
If the length of the window is 87 cm, what is its width?
Width of the window:
Answer:
Length of the garden: 96m
Width of the window: 56cm
Step-by-step explanation:
Answer:
L=96m
W=57cm
Step-by-step explanation:
General formula of the area of rectangle would be
Length * Width = Area
Length * 84 = 8064
By dividing both sides of equation by 84
Length = 8064/84 = 96m
General formula of the perimeter of rectangle would be
Perimeter = 2(Length + Width)
288 = 2(87 + Width)
By dividing both sides of equation by 2
144=87+Width
By substracting 87 from both sides of equation
144-87=Width
Width = 57cm

whats the surface area of this shape?
Answer:
168 square units
Step-by-step explanation:
From left to right, top to bottom
1. 5 x 10 = 50
2. 5 x 8 = 40
3. 5 x 6 = 30
For the triangles since there is 2 of them and there the same we play it like there is 1 square
4 & 5. 8 x 6 = 48
Now add all them
50 + 40 + 30 + 48
50 + 40 = 90
30 + 48 = 78
90 + 78 = 168
Answer:
168 square units
Step-by-step explanation:
5*10 = 50 (left rectangle)
8*6 = 48 (top and bottom triangles, not dividing by 2 as there is two of that exact shape)
5*8 = 40 (middle rectangle)
6*5 = 30 (right rectangle)
Add them all up
50+48+40+30 = 168.
