Answer:
A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position
EXAMPLES:

A pendulum is a simple device consisting of a weight suspended from a fixed point, allowing it to swing back and forth under the force of gravity
Pendulum: A pendulum is a simple device consisting of a weight suspended from a fixed point, allowing it to swing back and forth under the force of gravity. The bob is typically attached to a string, rod, or wire that allows for free movement.
When a pendulum is set in motion, it swings back and forth in a regular and repetitive pattern.
The motion of a pendulum is governed by several factors, including the length of the pendulum, the mass of the bob, and the gravitational acceleration.
The swinging motion of a pendulum is influenced by two fundamental principles:
1. Period: The period of a pendulum is the time it takes for the pendulum to complete one full swing from one side to the other and back. The period depends on the length of the pendulum and is not affected by the mass of the bob. A longer pendulum will have a longer period, while a shorter pendulum will have a shorter period.
2. Oscillation: The pendulum oscillates due to the force of gravity acting on the bob. As the pendulum swings to one side, it gains potential energy, which is then converted into kinetic energy as it swings back. This energy transfer causes the pendulum to continue swinging back and forth.

A theater is showing 2 comedies, 1 musical, and 5 action films. Each movie has 3 matinee showtimes and 7 evening performances. Each type of movie and showtime is equally likely to be chosen. If 12,400 people see a movie, how many will be expected to choose a musical during an evening showtime? A 1,085 C 1,240 B 1,189 D 1,550
Answer: 1550
Step-by-step explanation:
Number of people to see the movie = 12400
Number of comedies = 2
Number of musical = 1
Number of action films = 5
The number of people that'll be be expected to choose a musical during an evening showtime will be:

I NEED THE TABLE WITH X AND Y ALSO THE GRAPH
if x+2y =3 and 2x+y=3 then find x²+y²
Answer:
x² + y² = 2
Step-by-step explanation:
Given
x + 2y = 3 → (1)
2x + y = 3 → (2)
Rearrange (2) expressing y in terms of x by subtracting 2x from both sides
y = 3 - 2x → (3)
Substitute y = 3 - 2x into (1)
x + 2(3 - 2x) = 3 ← distribute and simplify left side
x + 6 - 4x = 3
- 3x + 6 = 3 ( subtract 6 from both sides )
- 3x = - 3 ( divide both sides by - 3 )
x = 1
Substitute x = 1 into (3) and evaluate for y
y = 3 - 2(1) = 3 - 2 = 1
Thus
x² + y² = 1² + 1² = 1 + 1 = 2

a. When x = -1, what is the value of y?
Continue on the following page.
b. When y = 7, what is the value of x?
c. What is the y-intercept of the graph?
d. What is the x-intercept of the graph?
e. What is the slope of the line?
f. What is the equation of the line?
Answer:
a. y = 3
b. x = 1
c. y-intercept = 5
d. x-intercept = -2.5
e. 2
f. y = 2x + 5
Step-by-step explanation:
Based on the graph, we can see the point where x is -1, y = 3.
Based on the graph, we can see the point where y = 7, x = 1.
Based on the graph, we can see the y-intercept is 5.
Based on the graph, we can see the x-intercept is -2.5.
To calculate the slope of the line, I will be using the points (-1, 3) and (0, 5).
Slope = [tex]\frac{rise}{run}[/tex]
= [tex]\frac{5-3}{0-(-1)}[/tex]
= [tex]\frac{2}{1}[/tex]
= 2
The equation of a line is: y = mx + c where m is the slope and c is the y-intercept. Thus, the equation of the line in this case is: y = 2x + 5

value of a in terms of b and c is: [tex]\mathbf{a=bc}[/tex]
Option D is correct.
Step-by-step explanation:
We are given:
[tex]a=b^2c^2d \:and\: d=\frac{1}{a}[/tex]
We need to find a in terms of b and c
We have: [tex]a=b^2c^2d[/tex]
Put value of d [tex]d=\frac{1}{a}[/tex]
[tex]a=b^2c^2(\frac{1}{a})\\a^2=b^2c^2\\Taking \:squareroot\:on\:both\:sides\\\sqrt{a^2}=\sqrt{b^2c^2}\\a=bc[/tex]
So, value of a in terms of b and c is: [tex]\mathbf{a=bc}[/tex]
Option D is correct.
Which is an equation of a direct proportion?
A. =1/3−2
B. =3/
C. =−3+4
D. =−3
Answer:
D. y=-3x
Step-by-step explanation:
Direct Proportion
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
[tex]\displaystyle \frac{y}{x}=k[/tex]
Where k is the constant of proportionality.
Solving for y:
y=kx

Ms. deng can walk 1 mile in 20 minutes. her sister can walk 2 miles in 1 hour. who walks faster? why? show all work.
Answer:
she is faster
Step-by-step explanation:
first find how long sister takes to walk 1 mile - if she walks 2 miles in 1 hour she'll take less time to walk 1 mile, 2/2 = 1 mile
and 60mins/2 = 30mins
so sister walks 1 mile in 30 minutes and she walks 1 mile in 20 mins so she is faster by 10 mins

∑(t² × f(t)) = 22,738.51, ∑f(t) = 8

Answer:
C.None of the above
Step-by-step explanation:
Let's consider the first answer choice:
The times in the semifinals were faster on average than the times in the finals.
We don't have to calculate the mean values of each distribution because we can see visually that the center of the final round distribution is lower than the center of the semifinal round distribution.
Since lower times are faster, we can't say that the times in the semifinals were faster on average than the times in the finals.
Now, let's consider the second answer choice:
The times in the finals vary noticeably less than the times in the semifinals.
We can see visually that the final round distribution is more spread out than the semifinal round distribution. We could calculate MAD or IQR from these displays, but we can see that the range of the final round distribution is larger.
So we can't conclude that the times in the finals vary noticeably less than the times in the semifinals.

What is the solution to the open sentence?
4x – 4 = 2x + 2
Answer:
x =3
Step-by-step explanation:
4x – 4 = 2x + 2
Solving for x
Subtract 2x from each side
4x-2x – 4 = 2x-2x + 2
2x-4 = 2
Add 4 to each side
2x-4+4 = 2+4
2x = 6
Divide each side by 2
2x/2 = 6/2
x =3

PLEASE HELP FOR BRAINLIEST!!! Find the lengths of the dashed sides of the diagram below. Make sure your answers are fully simplified.
Answer:
BC = 4, CD = 6
Step-by-step explanation:
Simply apply the distance formula.
(4 - 0) + (4 - 4) = 4
|(6 - 4, 0 - 4)| = 2 + 4 = 6
We take the absolute value when one term is negative because distance always ignores negatives.
