The height of a rider on the London Eye Ferris wheel in London can be modeled by the function h(t) = A * cos(B * t), where t represents time in minutes. The Ferris wheel stands 135 meters tall with a diameter of 120 meters. It takes half an hour (30 minutes) to complete one revolution.

1. At t = 0 minutes, the rider is not at the bottom of the wheel but at the midpoint of the wheel's diameter, so the rider's height is equal to the radius of the wheel, which is half of its diameter. Therefore, the rider's height at t = 0 minutes is 120/2 = 60 meters.

2. To determine the time it takes for the rider to reach the top, we need to find the period of the cosine function. The period (T) is the time it takes for one complete cycle of the function. In this case, the period is equal to the time it takes for the Ferris wheel to make a full revolution, which is 30 minutes. So, the rider reaches the top after half of the period, which is T/2 = 30/2 = 15 minutes. At that time, the rider's height is equal to the sum of the radius of the wheel and its height, which is 60 + 135 = 195 meters.

3. The period of the cosine function is T = 30 minutes.

4. The vertical shift of the function represents the average height of the rider throughout one complete cycle. In this case, the average height is the sum of the radius and the height of the Ferris wheel divided by 2, which is (60 + 135)/2 = 97.5 meters. Therefore, the vertical shift of the function is 97.5 meters. The amplitude of the function is half of the vertical distance between the maximum and minimum values, which is (135 - 60)/2 = 37.5 meters.

5. The equation of the cosine function is h(t) = 97.5 + 37.5 * cos((2π/30) * t). To find the rider's height at t = 21 minutes, we substitute t = 21 into the equation: h(21) = 97.5 + 37.5 * cos((2π/30) * 21) ≈ 185.11 meters.

In summary, the rider's height at t = 0 minutes is 60 meters. It takes 15 minutes for the rider to reach the top, at which point their height is 195 meters. The period of the function is 30 minutes. The vertical shift is 97.5 meters, and the amplitude is 37.5 meters. Using the cosine function, the rider's height at t = 21 minutes is approximately 185.11 meters.

Answer:

m = -48

Step-by-step explanation:

m - 11 = -59 (add 11 on both sides)

m = -48

Hope this helps!!

Answer:

m = -48

Step-by-step explanation:

m - 11 = -59

you add the 11 to both sides crossing it out from the left side and then you get an equation that looks like this.

m = -59 + 11

Now you can just solve it like a simple subtraction problem, -59 + 11 = -48

the rate of customers the Uber driver serves is approximately 1.875 persons per hour.

To calculate the rate of customers the Uber driver serves in units of persons per hour, we need to consider the average time it takes to complete a ride and the proportion of short distance and long distance riders.

Let's denote:

S = Proportion of short distance riders (0.9)

L = Proportion of long distance riders (0.1)

T_s = Average time for a short distance ride (20 minutes)

T_l = Average time for a long distance ride (40 minutes)

T_waiting = Average waiting time between rides (10 minutes)

First, we calculate the average time per ride:

Average time per ride = (S * T_s) + (L * T_l)

                    = (0.9 * 20) + (0.1 * 40)

                    = 18 + 4

                    = 22 minutes

Next, we calculate the average number of rides the Uber driver can complete in an hour:

Rides per hour = 60 minutes per hour / (Average time per ride + T_waiting)

             = 60 / (22 + 10)

             = 60 / 32

             = 1.875 rides per hour

The toy cars Anna must sell for her revenue to equal her expense is 4 toy cars. The result is obtained by using the concept of calculating algebra.

To calculate the algebra with one variable, sum up all the same variable and count the value.

Anna want to sell toy car at a craft fair. Each car is sold at a price of $ 12. The material for each car cost $ 3.50 and the table rental at the fair is 34 dollar for the day.

Find the toy cars must Anna sell for her revenue to equal her expense!

We have

Let's say

Revenue = Expense

a × $12 = (a × $3.5) + $34

12a = 3.5a + 34

12a - 3.5a = 34

8.5a = 34

a = 4 toy cars

Hence, Anna must sell 4 toy cars so that her revenue is equal to expense.

Answer:

Millie is 11. Molly is 8.

Step-by-step explanation:

Step 1: Subtract 3 from 19. The reason why you do this is to make sure that you don't have an extra 3 lying in there for the next few steps.

19-3=16

Step 2: Divide 2 from 16. You do this because there are two sisters.

16÷2=8

8 will then become Molly's age

Step 3: Add 3 to 8. This will give you Millie's age because she is 3 years older than Molly.

3+8=11

In conclusion, Millie is 11 and Molly is 8.

The cost of the fabric needed to make the square table cloth is $3.75

Firstly, it's essential to understand that the cost of the fabric is calculated per square foot. This means that the more square feet of fabric you use, the higher the cost will be. Therefore, the first step is to measure the dimensions of the tablecloth.

For instance, if the tablecloth is 5 feet long and 3 feet wide, the total area would be 15 square feet.

Next, you can multiply the total square footage of the tablecloth by the cost of the fabric per square foot.

In this case, if the cost of the fabric is $0.25 per square foot, the cost of the fabric needed for the tablecloth would be

=> 15 (total square feet) x 0.25 (cost per square foot) = $3.75.

Answer:

y = -x

Step-by-step explanation:

(0, 0) and ( -100, 100)

m= (y2-y1)/(x2-x1)

m=(100-0)/( -100 -0)

m = 100/ -100

m = -1

y - y1 = m(x - x1)

y - 0 = -1(x - 0)

y - 0 = -x + 0

y = -x

Answer:

The answer is 12.

Step-by-step explanation:

The area of an obtuse triangle can be found using the formula: Area = (1/2) * base * height.

To find the base and height of the triangle, we need to identify a right angle within the triangle. One way to do this is by drawing an altitude from one vertex to the opposite side.

Once we have the right angle, we can determine the base and height. The base is the length of the side to which the altitude is drawn, and the height is the length of the altitude itself.

Unfortunately, the given information does not provide any measurements or angles of the triangle. Therefore, we cannot calculate the area of the obtuse triangle accurately.  Hence, the answer cannot be determined with the given information.

Step-by-step explanation:

For the first line, you are copying the dimensions from the figure to the blanks. The dimensions on the figure are (4a +1), and (8), both in centimeters. When you have filled in that line, it will read ...

  2((4a +1) +8) cm

__

For the second line, you must collect terms and use the distributive property to eliminate parentheses from the above expression.

  2((4a +1) +8) cm = 2(4a +9) cm = 2(4a) +2(9) cm

  = 8a +18 cm

__

The third line simply sets this expression equal to the given perimeter, 42:

  8a +18 = 42

_____

Additional comment

To solve this equation, you can subtract 18 from both sides:

  8a +18 -18 = 42 -18

  8a = 24 . . . . . . . . . . . simplify

Then divide both sides by 8.

  8a/8 = 24/8

  a = 3

Finally, the length of the rectangle is ...

  4a +1 = 4(3) +1 = 12 +1 = 13

The rectangle is 13 cm long and 8 cm high. Its perimeter is ...

Using the given difference equation y(k) - (4/1)y(k-1) - (8/1)y(k-2) = 3u(k), and assuming initial conditions y(-2) = 0 and y(-1) = 0, we can solve for the first 50 values of y(k) using the iterative method explained above. The input function u(k) is given as u(k) = (2/1)^k u(k), where u(k) is the unit step function.

To solve the given difference equation, we need to find the solution for y(k) using the given initial conditions and the input function u(k).

The given difference equation is:

y(k) - (4/1)y(k-1) - (8/1)y(k-2) = 3u(k)

We are given the input function u(k) = (2/1)^k u(k), where u(k) is the unit step function.

To solve this difference equation, we'll start by setting up the initial conditions. Let's assume y(-2) = 0 and y(-1) = 0. Then we can find the solution for y(k) iteratively using the given difference equation and the input function u(k).

Using the initial conditions and the difference equation, we have:

k = 0:

y(0) - (4/1)y(-1) - (8/1)y(-2) = 3u(0)

y(0) - (4/1)(0) - (8/1)(0) = 3(1)

y(0) = 3

k = 1:

y(1) - (4/1)y(0) - (8/1)y(-1) = 3u(1)

y(1) - (4/1)(3) - (8/1)(0) = 3(2)

y(1) = -3

k = 2:

y(2) - (4/1)y(1) - (8/1)y(0) = 3u(2)

y(2) - (4/1)(-3) - (8/1)(3) = 3(4)

y(2) = 30

We continue this process for k = 3, 4, ..., 50 to find the solution for y(k).
