Please answer this fast. This was due October 6th and I need to get it done!!!!! The energy E of a moving object is called its
kinetic energy. It is calculated using the formula E = { mv2,
where m is the object's mass in kilograms and v is its
speed in meters per second. The units of kinetic energy are
kilograms - meters
abbreviated as kg • m²/s2.
seconda
a. Solve the given formula for m.
b. What is the mass of an object moving at 10 m/s with a kinetic
energy of 2500 kg · mº/s2?
. n
Answer:
Question a:
[tex]{ \rm{kinetic \: energy = \frac{1}{2} m {v}^{2} }} \\ [/tex]
• then let's make m the subject:
[tex]{ \rm{E = \frac{1}{2}m {v}^{2} }} \\ \\ { \rm{m {v}^{2} = 2E }} \\ \\ { { \green{ \boxed{ \boxed{ \bf{m = \frac{2E}{ {v}^{2} } }}}}}} \\ [/tex]
Answer: m = 2E/v²
Question b:
[tex]{ \rm{m = \frac{2E}{ {v}^{2} } }} \\ \\ { \rm{m = \frac{(2 \times 2500)}{ {10}^{2} } }} \\ \\ { \rm{m = \frac{5000}{100} }} \\ \\ { \boxed{ \boxed{ \rm{ \: m = 50 \: kg \: }}}}[/tex]

The questions is - What is the slope intercept? Then convert your answer to standard form.
please help me Im pretty sure the slope intercept is y=1 but I dont know what that would be as standard form would be
Answer:
y=1
Step-by-step explanation:
You're correct also graphed so you can see your answer is right
The graph is undedefined because it doesn't have a X and continues straight on one point. So for standard for you would put Y=1/undefined or just undefined

Find the slope of each line.
1)
2)
у
To find the slope of a line, remember:
[tex]slope=\frac{rise}{run}[/tex].
Also, the points that you choose to use to calculate your rise and your run must meet at an exact point, not in the middle of a block. In your graphs the points are the little blue dots, so that's already been done for you and that's what we'll use to calculate the slope!
Also, recall that the rise is how many blocks the line has changed vertically (so is one point lower/higher than another point)
The run is how many blocks the line has changed horizontally (so how many blocks over is the next point)
Therefore, for #1 we can see that the point on the right is over 3 blocks (run), and it goes down 1 block (rise).
So for #1, your answer is: [tex]slope=\frac{rise}{run}=\frac{-1}{3}[/tex] or [tex]-\frac{1}{3}[/tex]
For #2 we see that one point is higher by 3 blocks (rise) and it also goes over one block (run)
So, your answer to #2 is: [tex]slope=\frac{rise}{run}=\frac{3}{1}=3[/tex]
Hope this helps! :)

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).8, 20,50,...Find the 10th term.
The value of the 10th term of the geometric progression is 30517.578
Based on the information given,
First term = 8
Second term = 20
Common ratio = 20/8 = 2.5
The nth term of a geometric progression is calculated as:
= ar[tex]n[/tex] - 1
The 10th term will then be:
= 8 × (2.5)[tex]9[/tex]
= 8 × 3814.6973
= 30517.578
Therefore, the value of the 10th term of the geometric progression is 30517.578.

The 10th term of the geometric sequence is: 30,715.578.
In a geometric sequence, the quotient between consecutive terms is always the same, called common ratio q.
The equation for the nth term is:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.In this problem:
The first term is [tex]a_1 = 8[/tex].The common ratio is:[tex]q = \frac{50}{20} = \frac{20}{8} = 2.5[/tex]
Thus, the nth term is given by the following equation:
[tex]a_n = 8(2.5)^{n-1}[/tex]

June is the most coldest.
How?
Mention the temperatures
January=+6°F
June=-24°F
November=-2°F
Lowest is the coldest .(June is the coldest month)
January = 6°F
June = -24°F
November = -2°F

Using the line of random numbers to run one simulation,
what proportion of students tried out for a sport?
O 0.40
A study reported that about 40% of high school students
have tried out for a sport at their school. To find out if this
applies to Jessica's school, she surveyed an SRS of 20
students. Nine of them said that they had tried out for a
sport. To see if this result is surprising, a simulation is to
be conducted to estimate the probability of obtaining a
sample result as high as this one.
Let 0-3 represent students who tried out for a sport and
4-9 represent students who did not try out for a sport.

suppose another line for a chair lift is placed at a constant distance c below the gondola line. what is the equation of the new line? is the new line also parallel to the hill? explain.
Answer:
Yes They are Parallel.
Step-by-step explanation:
The required equation of the line y = ax + c as of the old line and also the line is parallel to the hill.
Given that,
Suppose another line for a chair lift is placed at a constant distance c below the gondola line. the equation of the new line and is the line parallel to the hill is to be discussed.
A line is a straight curve connecting two points or more showing the shortest distance between the initial and final points.
Here,
The required new line is placed at a constant distance c below the gondola line,
If the line has a constant distance from the other line that implies that the line is parallel, and the equation of the line is given as,
y = ax + c
Thus, the required equation of the line y = ax + c as of the old line and also the line is parallel to the hill.

A student wrote a photography manual which she plans to sell online for $ 13 per copy. Her total expenses were $ 55. Write a linear equation to show the relationship between x , the number of manuals the student sells, and y , the profit the student earns.
Answer:
y = 13x - 55
Step-by-step explanation:
So this is what we know
Selling price = $13 per copy
Expenses = $55
The formula for profit in this case is:
Profit = total selling price - expenses
In which y is the profit
The total selling price is 13x. x here is for the number of manuals she sells
The expenses are $55.
This then becomes y =13x - 55
