The kinetic energy of a body of mass 2 kg is 25 J. Its speed is??
Step-by-step explanation:
Kinetic Energy (K. E) = 25 J
Mass ( m) = 2 kg
Velocity or speed (v) = ?
We have the formula that
[tex]ke \: = \frac{1}{2} m {v}^{2} \\ or \: 25 = \frac{1}{2} \times 2 \times {v}^{2} \\ or \: 25 = {v}^{2} \\ or \: {5}^{2} = {v}^{2} \\ therefore \: v \: = 5 \: m |s[/tex]
it's speed is 5 m/s .
Hope it helps. :)
The speed of the body is 5 m/s
Applying the formular of kinetic energy
Kinetic energy: This can be defined as the energy posses by a moving body or that depends on the speed of a body.
The formular for kinetic energy is
E = mv²/2.................... Equation 1
Where E = Kinetic energy of the body, m = mass of the body, v = veocity/ speed of the body.
make v the subject of equation 1 above
v = [tex]\sqrt{2E/m}[/tex]................ Equation 2
From the question,
Given: E = 25 J, m = 2 kg
Substitute these values into equation 2
v = [tex]\sqrt{2*25/2}[/tex]
v = [tex]\sqrt{50/2}[/tex]
v = [tex]\sqrt{25}[/tex]
v = 5 m/s.
Thus, the speed of the body is 5 m/s

A concert had 6,000 audience members in attendance on the first night and the same on the second night. On the first night, the concert exceeded expected attendance by 20%, while the second night was below the expected attendance by 20%. What was the difference in percent of concert attendees and expected attendees for both nights combined?
Answer:
4%
Step-by-step explanation:
I added a screenshot of work, hopefully this helps you!
The difference in the percentage of concert attendees and expected attendees for both nights combined is 4%.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
Given that,
Number of audience attendants on the first and second night = 6,000
Let's say the excepted number of the audience on the first night was x then,
20% higher than x ⇒
1.2x = 6000
x = 5000
Error = 6000 - 5000 = 1000
Let's say the excepted number of the audience on the second night was x then,
20% lower than x ⇒
0.8x = 6000
x = 7500
Error = 7500 - 6000 = 1500
Combined expectation = 5000 + 7500 = 12500
Percentage = (1500 - 1000)/12500
Percentage = 0.04 → 4%
Hence "The difference in the percentage of concert attendees and expected attendees for both nights combined is 4%".

Two cards are drawn at random from a standard deck of cards. What is the probability of not
drawing a 10 or a Queen? Round the answer to the nearest hundredth of a percent.
Answer:
0.85
Step-by-step explanation:
A standard deck of cards has 52 cards. There are 4 10s and 4 Queens in the deck. There 8 cards that are 10s or Queens.
52 - 8 = 44
There are 44 out of 52 cards that are not 10s or Queens.
p(not 10 or Queen) = 44/52 = 0.85

There are 12 tomato plants in a garden. Each plant has 7 branches ad each branch has 4 tomatoes growing on it. If one-third of the tomatoes are picked, how many tomatoes were picked
Answer:
112
Step-by-step explanation:
4*7=2828*12=336336*(1/3)=112If one-third of the tomatoes are picked, the number of tomatoes that were picked is 112 tomatoes.
Number of picked tomatoes:Number of picked tomatoes=(Growing tomatoes× Tomatoes branch× Tomatoes plant)× One-third
Number of picked tomatoes=(4×7×12)×1/3
Number of picked tomatoes=336×1/3
Number of picked tomatoes=112 tomatoes
Inconclusion if one-third of the tomatoes are picked, the number of tomatoes that were picked is 112 tomatoes.

Judging by the table and how x = 1 and y = 2, you can estimate that y is twice as much as x.
This is supported by the equation, if you take 2 and multiply it by x (1) and take 3 and multiply it by y (2), then add the 2x1 (2) and 3x2 (6), you should get 8.

✑ Let's Know about A.M ( Arithmetic Mean )
In statistics , a single number can be calculated from a group of data which shows the character of the whole data. This number is called the average of the while data. An average is also called the arithmethic mean or simply mean which is a measure of central tendency.
☄ To calculate the average of the given type of data ( discrete series ) , follow the steps given below :
Make the table of 3 columns .Write down the items or observations ( x ) in the first column in ascending order and the corresponding frequency ( f ) in the second column.Multiply the data ( x ) by their corresponding frequency ( f ) and write down the product in third column of fx.Find the sum of f - column and fx - column separately.Divide the sum of fx by the sum of f , the quotient so obtained is the required mean.✐ Remember :
[tex] \underline{ \boxed{ \sf{mean \: = \frac{Σfx}{Σf} \: or \: \frac{Σfx}{n}}}} [/tex]
Where , Σf = N = Sum of the frequency and the symbol ' Σ ' ( sigma ) means " summation of " .

A car is traveling at a speed of 72 kilometers per hour. What is the car's speed in kilometers per minute? How many kilometers will the car travel in 2 minutes?
Do not round your answers.
72/60 to get the speed per minute which is 1.2 miles per minute. From there you can just multiply by 2 to get how far the car will travel in two minutes which is 2.4 kilometers. Not rounded btw.
SGA is doing a fundraiser to sell candles for project graduation. Small candles cost $4.00 and large candles cost $6.00. They have at most 50 candles, and want to make at least $100. Which system of linear inequalities represents the situation? x: The number of small candles y: The number of large candles
Given:
Cost of small candles = $4.00
Cost of large candles = $6.00
They have at most 50 candles, and want to make at least $100.
To find:
The system of linear inequalities represents the situation.
Solution:
Let x be the number of small candles and y be the number of large candles.
At most 50 candles means total candles must be less than or equal to 50.
[tex]x+y\leq 50[/tex]
Want to make at least $100. It means, the total sales must be greater than or equal to $100.
[tex]4x+6y\geq 100[/tex]
Therefore, the inequalities in the system of linear inequalities are [tex]x+y\leq 50[/tex] and [tex]4x+6y\geq 100[/tex].

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−1 intersect are the solutions of the equation 4x = 2x−1. (4 points)
Part B: Make tables to find the solution to 4x = 2x−1. Take the integer values of x between −4 and 4. (4 points)
Part C: How can you solve the equation 4x = 2x−1 graphically? (2 points)
(10 points)
Answer:
Part A: So the solution for 4 = 2x-1 is -2. Why they're intersecting is because x is -0.5 in both cases. 2/4, as we already know, is 0.5. Since, this -2/4, we can just make 0.5 negative, so -0.5. -0.5 times 4 = -2, so x is -0.5. For y = 2x-1, multiply -0.5 by 2, which would get you -1. Then after that subtract 1, for -2.
Part B:
Well, notice how none of the entries for y = 4x and y = 2x-1 match. That would mean the answer wouldn't be an integer. (Attachment is the table)
Part C:
First, graph both y = 4x and y = 2x-1. After that, find where the two equations' y-coordinates are the same (So, on a graph, where they intersect.). The y-coordinate in common is your answer.
Answer:
A: the intersection represents the answer because the place where it intersects is where the equations have the same x values.
B: they intersect at the point (0,1)
C: plot the equations on an online graph and solve, Its almost impossible to draw an accurate continuing graph for an exponential equation. I recommend desmos.

Answer:
g(f(x)) = x . . . so the functions are inverses
Step-by-step explanation:
Two functions f and g are inverses of each other if ...
g(f(x)) = x or f(g(x)) = x
We are asked to evaluate g(f(x)). That will be x if the functions are inverses.
g(f(x)) = g((x+1)/2) = 2((x +1)/2) -1 = (x +1) -1
g(f(x)) = x . . . . the functions are inverses

Answer:
m∠ABE = 62°
Step-by-step explanation:
Since, the given quadrilateral is a kite, diagonals will intersect at 90°.
Therefore, m∠AEB = m∠CEB = 90°
m∠BAE = 28° [Given]
m∠BCE = 58° [Given]
From ΔABE,
m∠BAE + m∠BEA + m∠ABE = 180°
28° + 90° + m∠ABE = 180°
m∠ABE = 180° - 118°
= 62°
Therefore, measure of angle ABE = 62°.
