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?

Answers

Answer 1

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

The area of a rectangular painting is 8613 cm?.
If the length of the painting is 99 cm, what is its width?

Answers

Answer:

The width is 87 cm

Step-by-step explanation:

The area of a rectangle is given by

A = l*w

8613 = 99 * w

Divide each side by 99

8613 / 99 = 99 w /99

87 = w

The width is 87 cm

Answer:

Step-by-step explanation:

Given

The area of a rectangular painting=8613 cm^2

Length of painting=99cm

Solution

Area of the rectangular painting=8613

Length×width=8613

99×width=8613

Width=8613/99

Width =87cm

Convert 1AA from hexadecimal to decimal.

Answers

1AA = 426

What an odd class...

Answer:

426 in decimal.

Step-by-step explanation:

Step 1) Count the digits in 1AA, which in this case is 3 digits, and convert each digit to Hex.

Step 2) Starting from the last number in Step 1, multiply the first number with 1, the second number with 16, and the third number with 256.

Step 3) Add up all the numbers you got in Step 2 to get the answer.

Following the instructions above, your math should look like this:

10 x 1 = 10

10 x 16 = 160

1 x 256 = 256

10 + 160 + 256 = 426

Thus, we got the following answer:

1AA = 426

If a function is defined by the formula y=1/2x + 3 and its domain is given by the set {-4,0,8}, then which of the following sets gives the function's range?

Answers

Answer:

y = {1, 3, 7}

Step-by-step explanation:

Given

y = ½x + 3

Domain: {-4, 0, 8}

Required

Determine the range of the function

To do this, we simply substitute each value of the domain in the given expression

We start with the first

Substitute -4 for x in y = ½x + 3

y = ½ * -4 + 3

y = -2 + 3

y = 1

Then 0

Substitute 0 for x in y = ½x + 3

y = ½ * 0 + 3

y = 0 + 3

y = 3

Lastly, 8

Substitute 8 for x in y = ½x + 3

y = ½ * 8 + 3

y = 4 + 3

y = 7

Hence, the range of the function is:

y = {1, 3, 7}

Answer: slope is [tex]\frac{7}{2}[/tex] or 3.5

Step-by-step explanation:

Slope =  [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{4-(-3)}{7-5}[/tex] = [tex]\frac{7}{2}[/tex]

Answer:

[tex]\boxed {\boxed {\sf m= \frac{7}{2} \ or \ 3.5 }}[/tex]

Step-by-step explanation:

The slope formula is the change in y over the change in x.

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

In this formula, (x₁, y₁) and (x₂, y₂) are the points given. We are given the points (5, -3) and (7,4). Therefore,

[tex]x_1=5 \\y_1= -3\\x_2=7 \\y_2=4[/tex]

Substitute the values into the formula.

[tex]m=\frac{4--3}{7-5}[/tex]

Solve the numerator.

4 - -3 = 4+3 = 7

[tex]m=\frac{7}{7-5}[/tex]

Solve the denominator

7-5=2

[tex]m=\frac{7}{2}[/tex]

[tex]m=3.5[/tex]

The slope between the points is 7/2 or 3.5

The solution for set B could be graphically represented with a number line that contained an unshaded circle surrounding the integer 5 and all values to the right of 5 or greater than 5 would be shaded.

If you placed the two number lines close to each other, you would see that they do not intersect.

Suppose that the amount of snowfall per storm in Lincoln is normally distributed with µ = 4.2 inches and standard deviation µ = 2.3 inches (totally made up data). If the mayor decides that only the top 5% of storms should have school cancelled, what is the cutoff snowfall for school to be cancelled?

Answers

Answer:

7.9835

Step-by-step explanation:

Given that :

Mean snowfall per storm (µ) = 4.2 inches standard deviation (s) = 2.3 inches

Only the top 5% of storm should result in school being canceled :

Cut off snowfall for school to be canceled '

P(Z ≥ 5%) ; p(Z ≥ 0.05) = 1.645

Using the z relation :

Z = (x - m) / s

1.645 = (x - 4.2) /2.3

x - 4.2 = 2.3 * 1.645

x - 4.2 = 3.7835

x = 3.7835 + 4.2

x = 7.9835

Cut off snowfall for school to be canceled 7.9835

Find endpoints on a standard normal distribution with the given property. The area between is about 0.88 . Round your answers to three decimal places and place the endpoints in increasing order.

Answers

Answer:

-1.555 and 1.555

Step-by-step explanation:

For a standard normal distribution:

P(- Ƶ ≤ Z ≤ Ƶ) = 0.88

The normal distribution on the curve is symmetrical about Z = 0

Thus

P( -Ƶ ≤ Z ≤ 0) = P( 0 ≤ Z ≤ Ƶ)

However;

This implies that:

P( -Ƶ ≤ Z ≤ 0)  +  P( 0 ≤ Z ≤ Ƶ) = 0.88

2P ( 0 ≤ Z ≤ Ƶ)  = 0.88

P( 0 ≤ Z ≤ Ƶ) = 0.44

P(Z ≤ Ƶ) - P( Z ≤ 0) = 0.44

Since P(Z ≤ 0) = 0.50

P(Z ≤ Ƶ) = 0.44 + 0.50

P(Z ≤ Ƶ) =  0.94

From the probability value table

z = 1.555

Thus the endpoints are:

-1.555 and 1.555
