The amount of kinetic energy required to move a couch is most likely to be a function of the weight of the couch.
What is kinetic energy?In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity.

Answer:
85 messages
Step-by-step explanation:
The system of equations for this is
35 + .10x
18 + .3x
where x = the number of text messages
Usually, you would use substitution or elimination to solve this problem. However, because the answer choices were given, you can just plug in the values.
When you plug in 85, or x = 85, you get 43.5 for both equations because
35 + .10(85) = 43.5 18 + .3(85) = 43.5
Therefore, the answer would be 85 messages becuase both plans will cost the same when you send 85 text messages!

24x,12
The GCF is [_]?
Answer:
GCF is 2 x 2 x 3 = 12Step-by-step explanation:
to get the GCF of 24 and 12
you have to factor each value, then choose all the copies of
factor and times or multiply them.
so,
24 = 2 2 2 3
12 = 2 2 3
GCF = 2 2 3
therefore, the GCF is 2 x 2 x 3 = 12

Answer:
5.3
Step-by-step explanation:
1.8x = 9.4
x = 5.3
The value of x that makes the equation true is 5.3, the correct option is D.
What is an Equation?An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.
The equations are useful in determination of unknown parameters.
The equation is,
0.3x + 5. 14 = 2.1x - 4.4
The equation is made of two expressions,
The expression 1 is : 0.3x + 5. 14
The expression 2 is : 2.1x - 4.4
The value of x that makes the equation true has to be determined.
0.3x + 5. 14 = 2.1x - 4.4
Grouping the like terms on one side.
5.14 +4.4 = 2.1x -0.3x
Solving the variables and constants
9.54 = 1.8 x
Dividing 1.8 on both sides of the equation.
x = 9.54 /1.8
x = 5.3
The value of x at which the equation is true is 5.3.

What's a better show, Trailer Park Boys or Adventure Time?
Answer:
adventure time 100%
Step-by-step explanation:
Both are the best shown in their place.
Trailer Park Boys:A mockumentary sitcom television series from Canada called Trailer Park Boys was created by Mike Clattenburg. The television series, which is a continuation of Clattenburg's 1999 movie of the same name, chronicles the misadventures of a group of trailer park residents, some of whom are ex-convicts, who reside in the fictitious Sunnyvale Trailer Park in Dartmouth, Nova Scotia. After making its Showcase debut on April 22, 2001, the program initially aired for seven seasons before coming to an end with an hour-long special on December 7, 2008. Three additional movies based on the TV show have been produced: The Movie (October 6, 2006); Countdown to Liquor Day (September 25, 2009); and Don't Legalize It (April 18, 2014).Adventure Time:Pendleton Ward produced the American fantasy animated television series Adventure Time[c] for Cartoon Network. The show centers on the exploits of Finn (Jeremy Shada), a young kid, and Jake (John DiMaggio), a dog with the magical ability to change size and shape at will. They engage with Princess Bubblegum (Hynden Walch), the Ice King (Tom Kenny), Marceline (Olivia Olson), BMO (Niki Yang), and other characters while living in the post-apocalyptic Land of Ooo.

3.8.10) Inclusions are defects in poured metal caused by contamitants. The number of (large) inclusions in cast iron follows a Poisson distribution with a mean of 2 per cubic millimeter. Deter mine the following:
(a) Probability of at least one inclusion in a cubic millimeter.
(b) Probability of at least 3 inclusions in 4.0 cubic millimeters.
(c) Volume of material to inspect such that the probability of at least one inclusion is 0.98
(d) Determine the mean inclusion per cubic millimeter such that the probability of at least one inclusion is 0.98.
Answer:
a) P(X>=1) = 0,7293 or P(X>=1) = 72,93 %
b) P(X>=3) = 0,5686 or P(X>=3) = 56,86 %
c) y = 0,8494 mm³
d) λ = 1,69897 inc per mm³
Step-by-step explanation:
a) P(X>=1) = 1 - P(X=0)
P(X = 0) = λ⁰ * e∧⁻λ / 0! where λ = 2 in/mm³
P(X = 0) = e∧-2 ⇒ P(X = 0) = 0,2706
Then
P(X>=1) = 1 - 0,2706
P(X>=1) = 0,7293 or P(X>=1) = 72,93 %
b) 3 inc. in 4 mm³ = 2*4/3 λ = 2,67 inc. per mm³
P(X>=3) = 1 - P(X=1 ) - P(X=2)
P(X=1) = λ¹ * e∧-λ / 1! ⇒ P(X=1) = 2,67 *e∧- 2,67/1
P(X=1) = 0,1846
P(X=2) = λ² * e∧-λ / 2! ⇒ P(X=2) = (2,67)² * e ∧ - 2,67/2
P(X=2) = 7,1289* 0,06925/2 ⇒ P(X=2) = 0,2468
Then
P(X>=3) = 1 - 0,1846 - 0,2468
P(X>=3) = 0,5686 or P(X>=3) = 56,86 %
c) P(X>=1) = 0,98
and λ = 2*y where y is the quantity of material
P(X=0) = 1 - P(X>=1)
P(X=0) = 1 - 0,98 P(X=0) = 0,02
0,02 = (2*y)⁰ * e ∧ -2*y /0!
0,02 = 1 * e ∧ -2*y
Taking log on both sides of the equation
log (0,02) = -2*y - 1,69897 = - 2*y
y = 0,8494 mm³
d) P(X >=1 ) = 1 - P( X = 0)
0,98 = 1 - P( X = 0)
P( X = 0) = 0,02
0,02 = λ⁰ * e ∧ - λ / 0!
0,02 = e ∧ -λ
Taking log on both sides of the equation we get:
log ( 0,02 ) = - λ
- 1,69897 = - λ
λ = 1,69897 inc. per mm³

What is the value of the expression below when w = 3. 4w^2 - 7w - 8
Step-by-step explanation: The prime factorization of 4320 is
2•2•2•2•2•3•3•3•5
To be able to remove something from under the radical, there have to be 2 instances of it (because we are taking a square i.e. second root).
√ 4320 = √ 2•2•2•2•2•3•3•3•5 =2•2•3•√ 30 =
± 12 • √ 30
√ 30 , rounded to 4 decimal digits, is 5.4772
So now we are looking at:
w = ( -40 ± 12 • 5.477 ) / -34
Two real solutions:
w =(-40+√4320)/-34=(20-6√ 30 )/17= -0.757
or:
w =(-40-√4320)/-34=(20+6√ 30 )/17= 3.110

Answer:
66 and 66Step-by-step explanation:
opposite angles are equal
12x - 18 = 8x + 10
combine similar terms:
12x - 8x = 10 + 18
4x = 28
x = 28/4
x = 7
plugin the value of x=7 back into the equation to solve the angle
= 12x - 18
= 12(7) - 18
= 66
= 8x + 10
= 8(7) + 10
= 66

Answer:
No, because one x-value corresponds to two different y-values ⇒ D
Step-by-step explanation:
The relation of x and y can be a function if every x has only one value of y (x not repeated)
Examples:
The relation {(3, 5), (-4, 6), (0, 5)} is a function because every x has only one value of yThe relation {(3, 5), (-4, 6), (3, -5)} is not a function because x = 3 has two values of y 5 and -5Let us check the given table
∵ At x = 2, y = 1
∵ At x = 3, y = 4
∵ At x = 4, y = 4
∵ At x = 5, y = 2
∵ At x = 5, y = 5
∵ x = 5 has two values of y 2 and 5
→ That means x is repeated
∴ Not every x has only one value of y
∴ The table does not represent a function
∴ The right answer is D
What is the slope of a line perpendicular to the line whose equation is
15x + 12y = -144. Fully reduce your answer.
Step-by-step explanation:
Hey there!
Let the unknown slope be M2.
The given equation is;
15x + 12y = -144
From equation;
[tex]slope( m) = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]
[tex]m = \frac{ - 15}{12} [/tex]
[tex]m = \frac{ - 5}{4} [/tex]
For the condition of perpendicular lines;
[tex]m \times m2 = - 1[/tex]
[tex] \frac{ - 5}{4} \times m2 = - 1[/tex]
[tex] - 5m2 = - 4[/tex]
[tex]m2 = \frac{ - 4}{ - 5} [/tex]
Therefore, the slope is 4/5.

Please help omg. ASAP.
Answer:
We have to find the equation of the red line
To get the equation of the line in the slope-intercept form,
we need its slope and its y-intercept
Finding the Slope
we know that the slope of a line is the rise of the line / run of the line between 2 points
here, the 2 points are already marked on the graph
So, slope = rise / run
we notice that the line rises only 2 units and runs 8 units between the points: (-5 , 3 ) and (3 , 5)
Slope = rise / run
now that we know the values of rise and run, we can plug the values to get the slope
Slope = 2 / 8
Slope = 1 / 4
Finding the y-intercept
We will now look at the point (-5 , 3) , we know that the slope is 1/4.
which means that every time the line moves 1 unit to the right, it also moves 1/4 units up
So, until the point (-1 , 4), the line has finally ascended 1 unit and now is at a proper coordinate
We can see that the line is only 1 unit to the left of the y-axis, so the y-coordinate of the line after moving 1 unit to the right is the y-intercept
since the line ascends 1/4 units every time it moves 1 unit to the right,
the ordinate of the line at the y-axis will be 1/4 more than the last ordinate (which was 4)
y-intercept = (4 + 1/4)
y-intercept = 17 / 4
Equation of the line
From the question, we know that the general form of the slope-intercept form is :
y = mx + b (where m is the slope and b is the y-intercept)
y = (1/4)x + (14/4)
y = (x + 14) / 4
