Answer:
Part A
5 m
Part B
The maximum displacement of the Ferris wheel from the midline
Step-by-step explanation:
Part A
The amplitude is the largest displacement of a body, moving in an oscillatory, or vibrational motion from its position of equilibrium or central position about which the body vibrates
In the Ferris wheel, the central position is the midline, between the maximum height and the minimum height
Therefore, the amplitude is the maximum displacement from the midline = The maximum height - ((The maximum height - The minimum height)/2 + The minimum height)
∴ The amplitude = 11 m - ((11 m - 1 m)/2) + 1 m) = 5 m
Part B
The amplitude represents the maximum and minimum distances the Ferris wheel moves above the midline.

Rotate triangle P 90° clockwise about the point (2, -1).
Please screenshot this and send me the answers cuz I really need help :(
Answer: (2,0), (2,1), and (6,1)
Step-by-step explanation: I just used the desmos graphing calculator to find the answer to your problem. I don't know any formulas to solve it so I just rotated the points by hand. I also made sure they were still equidistant from the point (2,-1) because if their distances from other points changed during the rotation, then the triangle would not be equal to the first triangle and the image would've been distorted.
I hope this helps! Have a nice day.

Step-by-step explanation:
the area of a circle is 81 pi m^2. what is the circumference, in meters? express your answer in terms of pi.
============================================================
Explanation:
The area 81pi square meters leads to the radius 9 meters
Use the formula A = pi*r^2 to see why this is the case. You plug in A = 81pi and solve for r to get r = 9.
-----------------
Once you know the radius, you can determine the circumference C
C = 2*pi*r
C = 2*pi*9
C = 2*9*pi
C = 18pi
The circumference is the perimeter, or distance, around the circle.
What is the value of x? (giving brainliest and thanks to all!)
Answer:
x = 12
Step-by-step explanation:
Given a line parallel to a side of the triangle and it intersects the other 2 sides then it divides those sides proportionally, that is
[tex]\frac{x}{24}[/tex] = [tex]\frac{5}{10}[/tex] ( cross- multiply )
10x = 120 ( divide both sides by 10 )
x = 12
Math question part 2 show work thanks Jim !!
Part (b)
The scale 1 cm = 2 m means we'll multiply whatever the cm distance is by 2 to get the meter distance in real life.
The shed is 3 cm by 3 cm on paper. It corresponds to 6 meters by 6 meters in real life.
----------
The cement pad is 6 meters by 10 meters in real life because it's originally 3 cm across and 5 cm vertical. We double each dimension as done before, and replace "cm" with "m".
----------
The hot tub is a circle so we don't get an exact measurement here. But we can determine a good estimate. It appears it's 2 cm across and 2 cm vertical. So that corresponds to 4 meters by 4 meters
=========================================
Part (c)
On paper, the distance is 4.5 cm since we count out 4 full squares plus half a square when going a horizontal distance from the cement pad to the pool.
Therefore, the distance in real life is 9 meters
1 cm = 2 m
4.5*(1 cm) = 4.5*(2 m)
4.5 cm = 9 m
==========================================
Part (d)
The flowerbed on paper has sides of 4 cm and 6 cm. Use the pythagorean theorem to find the hypotenuse is approximately 7.21 cm.
Double each dimension, and replace the 'cm' with 'm'
The side lengths of the actual flowerbed is 8 meters, 12 meters, 14.42 meters. That last value being approximate.
Add up the values to get the perimeter: 8+12+14.42 = 34.42
Answer: perimeter = 34.42 meters (approximate)
For two odd consecutive numbers, seven times the first number is 1 more than six times the greater number. What is the sum of those numbers?

Answer:
y = 3x + 1.
Step-by-step explanation:
The slope is 3 and the y-intercept is at y = 1.
Answer:
y = 3x + b
Step-by-step explanation:
Essentially the question is asking us to find the equation of the line in slope intercept form
Slope intercept form: y = mx + b
Where m = slope and y = y intercept
First let's find the slope
Slope = change in y over change in x
Looking at the line as y goes up 3 x goes up 1
hence slope (m) = 3/1 or just 3
Now let's find the y intercept
The y intercept is equal to the y value of the point where the line passes the y axis
The line passes the y axis at ( 0 , 1 ) and the y value of that point is 1
Hence, y intercept (.b ) = 1
Finally we substitute 3 for m and 1.for b in y = mx + b to get the equation of the line
We get y = 3x + 1.
What is the result when the number 82 is decreased by 8.6%? Round your answer to the nearest tenth.
Answer:
74.948
Step-by-step explanation:
Have a nice day
Answer:
74.948
Step-by-step explanation:
To decrease a number by a percentage, we can simply multiply the number by the reciprocal of the decrease.
To decrease 82 by 8.6 % , we can simply multiply 82 by 91.4%……..
82 x .914= 74.948
Rounded to nearest tenth……..74.9
David has a wooden board that is 6 feet long. How many pieces can be cut from the board if the length of each piece is 13 of a foot?
Answer:
We are dividing a slab of wood into equal pieces, so the obvious function would be to divide. And how long are the pieces going to be? 1/4 of a foot. so that gives us:
6 ÷ ¼.
Now, when we divide by a fraction, we flip the numerator and denominator and multiply, so the equation will look like:
6 * 4
Solve that, and you'll have your answer.
Step-by-step explanation:
Hope this answer helps you :)

3y = 60
y = 60/3
y = 20°
ALSO IN A PARALLELOGRAM ADJACENT SIDES SUM IS 180°
62 + 5x + 3 = 180°
5x + 65 = 180
5x = 180 - 65
5x = 115
x = 115/5
x = 23°

x = 4
4x + 14 = 3y + 9
4(4) + 14 = 3y + 9
16 + 14 = 3y + 9

3y = 30 - 9
3y = 21
y = 21/3
y = 7

0.4 kilowatt of electricity per hour. If
electricity costs $0.20 per kilowatt hour,
how much does it cost to run the player
for an hour?
Answer:

1. Shaded area is 14 cm. Find r to the nearest 0.01 cm.
Answer:
Step-by-step explanation:
Area of the quarter circle = 1/4 pi * r^2
Area of the quarter circle = 1/4 * 3.14 * r^2
Area of the triangle = 1/2 r * r = 1/2 r^2
Equation of Solution
1/4 3.14 * r^2 = 14 cm^2 + 1/2 * r^2 Subtract 1/2 r^2 from both sides
0.785 r^2 - 0.5 r^2 = 14 cm^2 Combine the left
0.285 r^2 = 14. cm^2 Divide by 0.285
r^2 = 14/0.285
r^2 = 49.1228 Take the square root of both sides
sqrt(r^2) = sqrt(49.1228)
r = 7.01
What is the volume of the cylinder shown? Use 3.14 for pi. 4cm is the radius and 9cm is the height.
Answer:
The formula is 4cm times 9cm which is 36cm. Then times that by pi which is 113.04. The answer is 113.04
Step-by-step explanation:
Answer:
Volume - 452.16 cm
Step-by-step explanation:
First we need to find the area of the circle.
Area of a circle - (3.14)r^2
Insert the radius in the formula -
(3.14) (4)^2
3.14 x 16
50.24 is the area of the circle
Now, we have to multiply this value by the height of the cylinder in order to find the volume.
50.24 x 9 = 452.16 cm

High population density can cause increases in competition for resources, such as food and shelter. The table shows the number of zebras living in four different regions.
A 3-column table has 4 rows. The first column has entries Region A, Region B, Region C, Region D. The second column is labeled Population of Zebras with entries 1,312, 630, 16,400, 17,800. The third column is labeled Area (kilometers squared) with entries 212, 314, 625, 902.
In which region is competition for resources most likely the greatest?
Region A
Region B
Region C
Region D
Answer:
C
Step-by-step explanation:
magic
The region with the competition for resources is region C with the highest population density
What is Population Density?The population density, or the number of people divided by the area's size, is determined by the number of people who reside there. Numerous creatures' distribution, growth, and migration can all be explained by population density.
Population density = number of people / the area they occupy
Given data ,
Let the population density be represented as P
Region Population Area
A 1,312 212
B 630 314
C 16,400 625
D 17,800 902
Now , the state with the highest population density will have the greater competition for the resources
So , The population density in Region A = 1312 / 212 = 6.19
The population density in Region B = 630 / 314 = 2
The population density in Region C = 16400 / 625 = 26.24
The population density in Region D = 17800 / 902 = 19.7
Hence , the region C has the highest population density
