U = potential energy of a spring at a certain position
k = the spring constant, specific to the spring, with units N/m.
x = distance the spring is stretched or compressed away from equilibrium
Potential Energy: Elastic Formula Questions:
1) A spring, which has a spring constant k = 7.50 N/m, has been stretched 0.40 m from its equilibrium position. What is the potential energy now stored in the spring?
Answer: The spring has been stretched x = 0.40 m from equilibrium. The potential energy can be found using the formula:
U = 1/2kx2
U = 1/2(7.50 N/m)(0.40 m)2
U = 0.60 N∙m
U = 0.60 J

f(x)=4^x and g(x)=4^x+2
State the type of transformation from f(x) to g(x) in the problem above and including its distance moved.
Answers
Given:
The two functions are:
[tex]f(x)=4^x[/tex]
[tex]g(x)=4^x+2[/tex]
To find:
The type of transformation from f(x) to g(x) in the problem above and including its distance moved.
Solution:
The transformation is defined as
[tex]g(x)=f(x+a)+b[/tex] .... (i)
Where, a is horizontal shift and b is vertical shift.
If a>0, then the graph shifts a units left.If a<0, then the graph shifts a units right.If b>0, then the graph shifts b units up.If b<0, then the graph shifts b units down.We have,
[tex]f(x)=4^x[/tex]
[tex]g(x)=4^x+2[/tex]
The function g(x) can be written as
[tex]g(x)=f(x)+2[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]a=0,b=2[/tex]
Therefore, the type of transformation is translation and the graph of f(x) shifts 2 units up to get the graph of g(x).
Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 125 millimeters, and a standard deviation of 7
millimeters.
If a random sample of 44 steel bolts is selected, what is the probability that the sample mean would be greater than 127.1 millimeters? Round your
answer to four
decimal places
Answers
Answer:
P(X > 127.1) = 0.0233
Step-by-step explanation:
We are given;
Population mean; μ = 125 mm
Sample mean; x¯ = 127.1 mm
Sample size; n = 44
Standard deviation; σ = 7 mm
Formula for test statistic is;
z = (x¯ - μ)/(σ/√n)
z = (127.1 - 125)/(7/√44)
z = 2.1/1.0553
z = 1.99
From z-table attached;
P(X > 127.1) = P(z > 1.99) = 1 - 0.97670 = 0.0233

Line A
Explanation:
Both lines have different patterns, but they both show that the amount of gallons of water increases as time increases. Line A moves more differently than line B. Line A shows an increase in that water is filling up quicker than line B. If you were to put points on a graph for both lines, you would figure out that the container for line A is filling up more quickly than the container in line B.
Answer:
Tank B
Step-by-step explanation:
Tank B is further than the point for tank A and it is lower than tank A so that means that it is filling up faster with less amount of water in it.

Answers
Given:
The sets are [tex]A=\{1,3,5,6\}[/tex] and [tex]B=\{0,7\}[/tex].
To find:
Whether A and B are disjoint sets or not.
Solution:
Two sets are called disjoint sets if there are no common elements between them.
We have,
[tex]A=\{1,3,5,6\}[/tex]
[tex]B=\{0,7\}[/tex]
Clearly, there is not common elements between the set A and set B.
Therefore, the sets A and B are disjoint sets.

How many lines of symmetry does the flower
have?
Answers
Answer:
6
Step-by-step explanation:
Each line can be placed directly in the middle of each pedal and continues down to middle of pedal across from it and same thing for the divit in between each pedal
The number of lines of symmetry does the flower have is to be considered as the 6.
Calculation of the number of lines of symmetry:In terms of geometry, symmetry refer to the balanced and proportionate similarity that should be found in two halves of an object. It represents one-half to be the mirror image of the other half.
So here we can see that there are 6 parts so here the number of lines of symmetry should be 6.

y = 45 / 2x + 50
Step-by-step explanation:
The best equation for the line of the best fit would be y = 45 / 2x + 50.
The slope would be 45 / 2 and the y-intercept would be ( 0 , 50 ).
I used the points, ( 0 , 50 ) and ( 4 , 140 ) to get the equation, slope, and the y-intercept.
I used those points because they were the most accurate ones that I know for now.
Also, remember the formula is, "y = mx + b."

In how
many ways can the letters of the word TABLE be arranged
so that the vowels are always together and seperated
Answers
Answer:
48 ways
Step-by-step explanation:
Treat the vowels as 1 unit by itself which in this case is A & E.
Imagine filling in 4 slots:
_ _ _ _ , since A&E are treated as 1 letter.
Thus we have 4 ways to fill in 1st slot, 3 ways for 2nd, 2 for 3rd and 1 for last.
which makes 4 * 3 * 2 * 1 = 24.
However, do note A&E can be arranged as AE or EA meaning,
we need to multiply by 2 factorial.
24 * 2 = 48
