The rate of interest is given by the equation R = 3.5 %
What is Simple Interest?Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.
Simple Interest = ( Principal Amount x Rate x Time Period ) / 100
Given data ,
Let the rate of interest be represented as R
Now , the simple interest I = $ 175
The principal amount invested P = $ 2,500
The time period T = 2 years
Simple Interest = ( Principal Amount x Rate x Time Period ) / 100
Rate of Interest = (Simple Interest x 100 ) / Principal Amount x Time Period )
Substituting the values in the equation , we get
Rate of Interest R = ( 175 x 100 ) / ( 2500 x 2 )
Rate of Interest R = 17500 / 5000
Rate of Interest R = 3.5 %
Hence , the interest rate is 3.5 %

The graph that has a slope of negative three halves and a y-intercept of 2 is the graph of a line passing through the points (0,2) and (3,0).
What is the slope?
One of the most important things to understand about lines is the definition of slope. The slope is the 'steepness' of the line, also commonly known as rise over run. We can calculate the slope by dividing the change in the y-value between two points over the change in the x-value.
To find the slope of the line, you can use the point-slope formula which is (y2-y1)/(x2-x1) = m,
where m is the slope and (x1,y1) and (x2,y2) are points on the line.
So using the given points in the question, we get (0-2)/(3-0) = -2/3 = -0.66 = -3/2.
And the y-intercept is the point where the line crosses the y-axis, which is 2 in this case.
Hence, the graph that has a slope of negative three halves and a y-intercept of 2 is the graph of a line passing through the points (0,2) and (3,0).

During 2012, Texas had listed on FracFocus, and industry tracking disclosure site, nearly 6000 oil and gas wells in which the fracking methodology was use to extract natural gas. Fontenot et al. (2013) reports on a study of 100 private water wells in or near the Barnett Shales in Texas. There were 91 private wells located within 5 km of an active gas well using fracking, 4 private wells with no gas wells located within a 14 km radius, and 5 wells outside of the Barnett Shale with no gas well located with a 60 km radius. They found that there were elevated levels of potential contaminants such as arsenic and selenium in the 91 wells closest to natural gas extraction sites compared to the 9 wells that were at least 14 km away from an active gas well using the fracking technique to extract natural gas.

what is the solution of √2x+4 - √x = 2
please show with work done!
Answer:
x=1
Step-by-step explanation:
To solve the equation, we'll need to get the square roots on one side and the non-square root terms on the other side.
First, we'll add √x to both sides to get:
√2x+4 - √x + √x = 2 + √x
√2x+4 = 2 + √x
Next, we'll square both sides to get rid of the square roots:
(√2x+4)^2 = (2 + √x)^2
2x+4 = 4 + 2√x + x
Then, we'll simplify the right side of the equation:
2x+4 = 4 + 2√x + x
2x+4 = 4 + x + 2√x
Now we'll subtract 4 from both sides
2x = x + 2√x
x = 2√x
Finally, we'll divide by x on both sides
1 = 2√x/x
x = √x
x = 1
Therefore, the solution of the equation is x=1
Answer:
To solve the equation √2x+4 - √x = 2, we can first square both sides of the equation to eliminate the square roots.
Squaring both sides gives: (√2x+4)^2 - (√x)^2 = 2^2
Simplifying the left side gives: 2x+4 - x = 4
Next, we can add x to both sides of the equation to get:
2x+4 = 4 + x
then we can subtract 4 from both sides of the equation to get:
2x = x
then we can divide both sides by x
2 = 1
However, it is not possible to divide by zero, so x = 0 is not a valid solution.
This equation is an extraneous solution because the assumption that x is not equal to 0 led to a valid solution, but when x = 0, the equation is not defined.
Therefore, the solution of √2x+4 - √x = 2 is x = any value except 0.

Which of the following is a logarithmic function?
Oy=log, X
Oy=3*
Oy=x+3
O y=x³
y = log (x)
Step-by-step explanation:Logarithmic functions are the inverse of exponential functions. Logarithmic is usually shortened to log.
Logarithmic Operation
Logarithmic functions help solve exponential equations. For example, the exponential function: bˣ = a, could be difficult to solve. To find x, we can use the log operation. By taking the log of both sides we can change this exponential function into a log function. In log form, the function becomes [tex]log_{b} (a)=x[/tex]. This is pronounced, "log-base b of a equals x." If you plug this into a calculator or use a different technique to solve, you can find x and solve the original exponential function.
Common Log and Natural Log
Although logarithmic functions can have any base, some are more frequent than others. One such base is base 10. If the base of the log is 10, then we do not write the 10, it is just implied. This log is called common log. The answer choice y = log (x) is common log. Another common base is Euler's constant, e. Log with the base of e is called natural log. Natural log is written as ln (x).
Prove that the limit x tends to 1 (2x^4-6x^3+x^2+3)÷(x-1)=-8
Answer:
full answer in below
Step-by-step explanation:
To prove that the limit of (2x^4-6x^3+x^2+3)÷(x-1) as x approaches 1 is equal to -8, we can use the definition of a limit and the fact that (x-1) is not equal to zero at x=1.
The definition of a limit states that:
If we have a function f(x) and a number L, then the limit of f(x) as x approaches a is L, if and only if, for every ε > 0, there exists a δ > 0 such that for every x:
|f(x) - L| < ε when 0 < |x - a| < δ
So, to prove that the limit of (2x^4-6x^3+x^2+3)÷(x-1) as x approaches 1 is -8, we need to show that:
|(2x^4-6x^3+x^2+3)÷(x-1) + 8| < ε when 0 < |x - 1| < δ
We know that (x-1) is not equal to zero at x=1, so we can safely divide both sides of the equation by (x-1) and simplify it to:
|2x^4-6x^3+x^2+11| < ε when 0 < |x - 1| < δ
Now, we can choose ε = 0.1 and δ = 0.1, so we have:
|2x^4-6x^3+x^2+11| < 0.1 when 0 < |x - 1| < 0.1
If we plug in x=1, we have:
|2(1)^4-6(1^3)+(1)^2+11| < 0.1
which simplifies to:
|11| < 0.1
and we see that this is true, since |11| = 11 is less than 0.1.
We can also plug in some values around x=1, for example x=0.99 and x=1.01:
|2(0.99)^4-6(0.99)^3+(0.99)^2+11| < 0.1
and
|2(1.01)^4-6(1.01)^3+(1.01)^2+11| < 0.1
In both cases, we can see that the inequality is true, and the absolute value of the expression on the left side is less than 0.1.
Therefore, we have shown that for any ε > 0, there exists a δ > 0 such that for every x:
|(2x^4-6x^3+x^2+3)÷(x-1) + 8| < ε when 0 < |x - 1| < δ
And thus, by the definition of a limit, we have proven that the limit of (2x^4-6x^3+x^2+3)÷(x-1) as x approaches 1 is -8.

Answer:
y-int = -1
x-int = -4
HA: y = -2
VA: x = -5
Step-by-step explanation:
For the y-intercept, you need to look where the graph intersects with the y-axis. In this case, the graph intersects at -1.
For the x-intercept, you need to look where the graph intersects with the x-axis. In this case, the graph intersects at -4.
The horizontal asymptote is a y value the graph approaches but does not pass or touch. In this case, the y value is -2.
The vertical asymptote is a x value the graph approaches but does not pass or touch. In this case, the x value is -5.
The cork in a wine bottle should not exceed 8.77KPa of normal stress. If the shear stress induced by the friction of its perimeter with the bottle is 4.98KPa, which is the maximum allowed ratio between the cork length H and the cork radius R?
The maximum allowed ratio for the cord such that the maximum allowable normal stress is 8.77 kilopascals is equal to 2.081.
How to determine the maximum allowed ratio of a cork in a wine bottle
Let assume that the cork is made of a ductile material, in this case we find that the normal stress (σ), in kilopascals, and shear stress (τ), in kilopascals, are described below:
Normal stress
σ = F / A
Shear stress
τ = (3 · V) / (2 · A')
Where:
V - Shear force, in kilonewtons.F - Normal force, in kilonewtons. A - Transversal area, in square meters. A' - Transversal shear area, in square meters.Let assume that cork is at static equilibrium and at inminent motion, then the shear and normal forces are, respectively:
F = P
V = P / 2
And the transversal areas are introduced below:
A = π · R²
A' = 2 · R · H
Where:
R - Radius of the cork, in meters.H - Height of the cork, in meters.If we know that σ = 8.77 kPa and τ = 4.98 kPa, then the maximum allowed ratio between the cork height and the cork radius is:
8.77 = P / (π · R²)
8.77 = [1 / (π · R)] · (P / R)
4.98 = 1.5 · (0.5 · P) / (2 · R · H)
4.98 = [0.75 / (2 · H)] · (P / R)
Then, we eliminate P / R of the two equations:
8.77π · R = 13.24 · H
H / R = 8.77π / 13.24
H / R = 2.081

For this specific case,
[tex]\boxed{P_n = 20000(0.98)^n}[/tex]
b) Population in 2025 will be the population after 25 years:
[tex]P_{25} = 20000(0.98)^{25} = \boxed{12,069}[/tex]
Step-by-step explanation:
In general, if the population at year 0 is P and it decreases by 2% each year then the population after one year will be given by
P - decrease in one year
Decrease in population for 1 year = 2% of P [tex]= 0.02P[/tex]
So P(after 1 year) :
[tex]P - 0.02P\\\\ = P(1-0.02) \\\\= 0.98P[/tex]
After 2 years the population will be population after 1 year (0.98P) - decrease in population for 1 year (0.02 x 0.98P)
So population at end of 2 years would be
[tex]0.98P - 0.98P(0.02)\\\\= 0.98P(1-0.02)\\\\=0.98P(0.98)\\\\= P(0.98)^2[/tex]

How to obtain the mean of a data-set?The mean of a data-set is obtained as the sum of all the elements in the data-set divided by the number of elements in the data-set.
The scores for this problem are given as follows:
83, 70, 83, 80 and x.
(in which x is the score of the fifth test).
The least score that you could get on the last test and still earn a C is found when the mean is of 70, hence>:
(83 + 70 + 83 + 80 + x)/5 = 70
316 + x = 350
x = 350 - 316
x = 34.
With the final test counting twice, you would have the equivalent to six scores, which would be given as follows:
83, 70, 83, 80, x and x.
Hence the least score would be obtained as follows:
(83 + 70 + 83 + 80 + 2x)/6 = 70
316 + 2x = 420
2x = 104
x = 104/2
x = 52.

All of the employees at the acmesoft company are either programmers or salespeople. The programmers are always tell the truth, the salespeople always lie. Threes Acmesoft employees - A, B, and C-were standing together in the hallway. A visitor passed by and asked A. "Are you a programmer or a salesperson?" A mumbled an answer that the visitor could not hear clearly. The visitor then asked B, "what did A say?" B replied. "A said that he is a salesperson."At this point, the third employee, C, said ,"Don't believe B; he is lying! What are B and C?
1/ B and C are both programmers
2/ B is a programmer and C is a salesperson
3/ B is a salesperson and C is a programmer
4/ B and C are both salesperson
Answer:
Step-by-step explanation:
3/ B is a salesperson and C is a programmer.
The correct option is: 2/ B is a programmer, and C is a salesperson
Let's analyze the statements and determine what B and C are:
A mumbled a response that the visitor couldn't hear clearly. We don't have any information from A's response.
B said, "A said that he is a salesperson." Since we know that salespeople always lie, we can infer that B is lying about A's response. Therefore, if A is a programmer (telling the truth), then B must be a salesperson.
C said, "Don't believe B; he is lying!" If we already determined that B is a salesperson (lying about A's response), then C is suggesting that B's statement is false, which means A's response is the opposite of what B said. So if B claimed that A is a salesperson (which was a lie), then A must be a programmer (telling the truth).
Based on the above analysis:
A is a programmer.
B is a salesperson.
C is a programmer.
So, the correct option is: 2/ B is a programmer, and C is a salesperson.
