What is the kinetic energy of a 54 kg mass traveling at 15 meters per second?
kg * m/8
405
kg * m^2/8^2
6075
kg * m/8
420
kg * m^2/8^2
12,150
Given that an object with a mass of 54kg travels at 15m/s^2, determine the kinetic energy of the object.
KE = 0.5 x mv^2
M (mass) = 54kg
V (velocity) = 15m/s^2
Then, we plug the values in.
KE = 0.5 x 54(15^2)
Now, we solve.
KE = 0.5 x 54(225)
KE = 0.5 x 12150
KE = 6075
Now, that we have solved the formula, we can see that the kinetic energy of the object is 6,075J.
Thus, the kinetic energy of the object is 6,075J.

Answer:
Mark earns 12 dollars an hour, and Steven earns 15 dollars.
Mark earned 6*12=72 dollars, and Steven earned 15*5=75 dollars.
Step-by-step explanation:
Let's set Mark's salary as x.
Steven=x+3
Last Friday, Steven earned 5(x+3) dollars, while Mark earned 6x dollars.
We can write the sum of these salaries as:
5(x+3)+6x=147
5x+15+6x=147
11x+15=147
11x=132
x=12
Then, we can substitute x with 12.
Mark earns 12 dollars an hour, and Steven earns 15 dollars.
Mark earned 6*12=72 dollars, and Steven earned 15*5=75 dollars.
Answer: Mark earns 12 dollars an hour, and Steven earns 15 dollars.
Mark earned 6*12=72 dollars, and Steven earned 15*5=75 dollars

Find the volume of this prism 5cm,12,cm 15cm,6cm 8cm
Answer:
840 cm³
Step-by-step explanation:
In the figure attached, the prism is shown.
The prism can be divided into two rectangular prisms, one at the top, with dimensions 5 x 4 (= 12 - 8) x 6 cm, and the other one at the bottom with dimensions 15 x 6 x 8 cm.
Area of the first prism: 5*4*6 = 120 cm³
Area of the second prism: 15*6*8 = 720 cm³
Then, the volume of the complete prism is 120 + 720 = 840 cm³
The required total volume of the complete prism is 840 cm³.
We have to determine, The volume of the prism 5cm,12,cm 15cm,6cm 8cm.
According to the question,
The prism can be divided into two rectangular prisms,
First part at the top, with dimensions [tex]= 5 \times 4 \times( 12 - 8) = 5\times 4 \times 6 cm,[/tex]
And the other part one at the bottom with dimensions [tex]= 15 \times 6 \times 8 cm.[/tex]
Area of the first prism: [tex]5\times4\times6 = 120 cm^{3}[/tex]
Area of the second prism: [tex]15\times6\times8 = 720 cm^{3}[/tex]
Then, The Total volume of the complete prism is 120 + 720 = 840 cm³
Hence, The required total volume of the complete prism is 840 cm³.

What information relevant to calculating are do we have available for this triangle?
Answer:
Well, since we are not given any graphics or additional information, I'll resort to listing four triangle area formulas:
1) triangle area = (1/2) * base * height
2) Heron's Formula ("s" = semiperimeter, which is the sum of all 3 sides divided by two)
triangle area = square root [s * (s - side a) * (s - side b) * (s - side c)]
3) For 2 sides and the INCLUDED Angle:
Area = side 1 * sine (angle A) * side 2

Step-by-step explanation:
select the function that represents a parabola with vertex at (2,-1) and a point (5,8) on its curve
a.) f(x)=2(x+2)^2-1
b.) f(x)=(x+2)^2-1
c.) f(x)=(x-2)^2-1
d.) f(x)=2(x-2)^2-1
Answer:
Correct answer is c.) [tex]f(x)=(x-2)^2-1[/tex]
Step-by-step explanation:
The vertex form of a parabola can be written as following:
[tex]y = a(x-h)^2 + k ....... (1)[/tex]
[tex](h,k)[/tex] is the co-ordinate of vertex.
[tex]a[/tex] is a constant whose positive or negative value decides where the parabola opens (up or down).
[tex](x,y)[/tex] are the points on parabola.
[tex]y[/tex] and [tex]f(x)[/tex] are interchangeable terms. We can use any of them.
For convenience with the co-ordinates in [tex]xy-[/tex]plane, [tex]y[/tex] is used here.
We are given that vertex is at (2,-1) and there is a point (5,8) on the curve.
i.e. h = 2 and k = -1,
x = 5 and y = 8
Putting the four values in equation (1):
[tex]8 = a(5-2)^2 + (-1)\\\Rightarrow 8 = a(9) -1\\\Rightarrow 9 = 9a \\\Rightarrow a = 1[/tex]
Putting values of [tex]a[/tex] and [tex](h,k)[/tex] in equation (1) to find the equation of parabola:
[tex]y=(x-2)^2-1[/tex]
As told earlier as well, [tex]y[/tex] and [tex]f(x)[/tex] are interchangeable terms.
So, correct equation of parabola is option C) [tex]f(x)=(x-2)^2-1[/tex]
Lydia writes the equation below with a missing value.
y=5x-[]
She puts a value in the box and says that the equation represent a direct variation. Which explains whether the equation could represent a direct variation?
A.The equation has a minus sign, so it cannot represent a direct variation.
B.If she puts 5 in the box, she would have a direct variation.
C.If she puts 0 in the box, she would have a direct variation.
D.The equation is not of the form y = kx, so it cannot represent a direct variation.
Answer:
If she puts 0 in the box she would have a direct variation.
Step-by-step explanation:
Given : Lydia writes the equation y = 5x - __ with a missing value.
She puts a value in the box and says that the equation represents a direct variation.We have to choose the correct option from the given options that explain that the equation could represent a direct variation.When two variables are such that one is a constant multiple of other, we said they are in Direct variation.
That is in form of y = ax , here y and x are in direct variation.Consider the given equation y = 5x - __
For the equation to be in direct variation the value of missing term has to be 0.
then equation becomes,y = 5x
Thus, If she puts 0 in the box she would have a direct variation.
Option (a) is correct.
a new car, originally worth $35,795, depreciates at a rate of 17% per year. The value of the car can be represented by the equation y=35795(0.83), where x represents the number of years since purchase and y represents the value (in dollars) of the car. How much will the car be worth five years after it is first purchased? How do you know? describe your calculation process.
We have been given that a new car, originally worth $35,795, depreciates at a rate of 17% per year. The value of the car can be represented by the equation [tex]y=35795(0.83)^x[/tex], where x represents the number of years since purchase and y represents the value (in dollars) of the car.
To find the value of car of after 5 years, we will substitute [tex]x=5[/tex] in our given equation as:
[tex]y=35795(0.83)^5[/tex]
[tex]y=35795\cdot (0.3939040643)[/tex]
[tex]y=14099.79598[/tex]
Upon rounding to nearest tenth, we will get:
[tex]y\approx 14099.8[/tex]
Therefore, the car will be worth $14,099.8 after 5 years it is first purchased.
Since $14,099.8 is less than original value of car, therefore, we know hat value of car is depreciating and $14,099.8 is correct answer.
We also know that an exponential decay function is in form [tex]y=a(1-r)^x[/tex], where,
y = Final value after t years,
a = Initial value,
r = Decay rate in decimal form,
x= Time.
[tex]17\%=\frac{17}{100}=0.17[/tex]
[tex]y=35795(1-0.17)^x[/tex]
[tex]y=35795(0.83)^x[/tex]

A solid silver paperweight in the form of a square pyramid is shown below. If silver costs $0.12 per cubic centimeter, how much would it cost to manufacture 6 paperweights?
Answer:
It would cost $232.32, this answer is rounded.
Step-by-step explanation:
The formula for the volume of a square pyramid is:
[tex]V=a^2\frac{h}{3}[/tex]
So its just:
[tex]8.8^2\frac{12.5}{3} = 322.67 cm^3[/tex]
Then you just multiply the volume by the cost per cubic centimetre:
[tex]322.67cm^3*$0.12=$38.704[/tex]
After just multiply the cost of one by how many you want, which is 6:
[tex]38/704*6=232.32[/tex]
The cost to manufacture 6 paper weight is $232.32
Volume of a square pyramid:v = 1 /3 b²hwhere
b = base
h = height
Therefore,
v = 1 / 3 × 8.8² × 12.5
v = 1 / 3 × 77.44 × 12.5
v = 968 / 3
v = 322.666666667 cm³
1 cm³ = $0.12
322.67 cm³ = ?
cost of a paperweight = 322.67 × 0.12 = $38.72
Therefore,
1 paper weight = $38.72
6 paper weight = ?
cross multiply
cost of 6 paper weight = 6 × 38.72
cost of 6 paper weight = $232.32

Emmy used one-centimeter cubes to build a larger cube. The edges of Emmy's cube are 3 centimeters long. Tim has a cube-shaped box with edges that are 3 times as long as the edges of Emmy's cube. How much larger in volume is Tim's box than Emmy's cube?
Answer:
Tim's box volume is 27 times greater than Emmy's.
Step-by-step explanation:
The volume of a cube is given by the following expression:
volume = l³
Since Emmy's cube have a 3 centimeters long edge, then it's volume is:
volume1 = 3³ = 27 cm³
On the other hand Tim's cube has an edge that is 3 times as long as Emmy's, so it's 9 centimeters long. Therefore it's volume is:
volume2 = 9³ = 729 cm³
The relation between the volume is given by:
ratio = volume2/volume1 = 729/27 = 27
Tim's box volume is 27 times greater than Emmy's.
