The value of the rational expression of equation is A = -1/5
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
A = ( 2x - 1 ) / ( x + 5 )
when x = 0
Substituting the values in the equation , we get
A = ( 2 ( 0 ) -1 ) / ( 0 + 5 )
On simplifying , we get
A = -1/5
Hence , the equation is solved and A = -1/5 when x = 0

You decide to put $150 in a savings account to save for a $3,000 down payment on a new car. If the account has an interest rate of 2.5% per year and is compounded monthly, how long does it take you to earn $3,000 without depositing any additional funds?
(I know it's 119.954 years, but I have no idea how to get that)
Answer:
It take 119.954 years to earn $ 3000 without depositing any additional funds.
Step-by-step explanation:
Given:
Principal Amount, P = $ 150
Amount, A = $ 3000
Rate of interest, R = 2.5% compounded monthly.
To find: Time, T
We use formula of Compound interest formula,
[tex]A=P(1+\frac{R}{100})^n[/tex]
Where, n is no time interest applied.
Since, It is compounded monthly.
R = 2.5/12 %
n = 12T
[tex]3000=150(1+\frac{\frac{2.5}{12}}{100})^{12T}[/tex]
[tex]\frac{3000}{150}=(1+\frac{2.5}{1200})^{12T}[/tex]
[tex]20=(1+\frac{2.5}{1200})^{12T}[/tex]
Taking log on both sides, we get
[tex]log\,20=log\,(1+\frac{2.5}{1200})^{12T}[/tex]
[tex]1.30103=12T\times\,log\,(1.002083)[/tex]
[tex]T=\frac{1.30103}{12\times\,log\,(1.002083)}[/tex]
[tex]T=119.954[/tex]
Therefore, It take 119.954 years to earn $ 3000 without depositing any additional funds

Is it possible for a segment to have more than one bisector? Explain your reasoning.
Final answer:
Yes, a segment can have more than one bisector. A bisector divides a segment into two equal parts.
Explanation:
Yes, a segment can have more than one bisector. A bisector of a segment is a line, segment, ray, or plane that divides the segment into two equal parts. Each bisector intersects the segment at its midpoint. Since the definition of a bisector doesn't specify uniqueness, there can be infinitely many bisectors of a given segment, especially in a two-dimensional plane.
For example, if you have a horizontal line segment, you could have one vertical bisector that divides it in the middle, but you could also have an infinite number of bisectors at various angles that also pass through the midpoint. Thus, there are multiple bisectors for any given line segment. Thus, consider two points A and B on a straight line segment AB. According to geometric principles, you can draw a perpendicular bisector that would be unique in the sense that it's the only line that both bisects AB and is perpendicular to it

Which of the following functions illustrates a change in amplitude?
A. y = 3cos4x
B. y = 1+sinx
C. y = -2-cos(x - pi)
D. y = tan2x
Answer:
Correct option is A.
Step-by-step explanation:
Given the following functions we have to choose the option which illustrates a change in amplitude.
Multiplying a sine or cosine function by a constant changes the graph of the parent function i.e results in change in the amplitude of function. Amplitude is the measure of distance from the sinusoidal axis to the maximum or the minimum.
Option A: y = 3cos4x
The parent function is f(x) = cos x.
The amplitude of function changes from 1 to 3.
Option B: y = 1+sinx
The parent function is f(x) = sin x
The amplitude remains same i.e 1
Option C: y = -2-cos(x - pi)
Here also remains same.
Option D: y = tan 2x
The tangent function does not have an amplitude because it has no maximum or minimum value.
Hence, correct option is A.
Answer:
y= 3cos4x

Find the greatest perfect square that is factor of the number. 650
The greatest perfect square that is a factor of 650 is 25
What is Perfect Square?A perfect Square is defined as an integer multiplied by itself to generate a perfect square, which is a positive integer. Perfect squares are just numbers that are the products of integers multiplied by themselves,
What is Prime Factorization?Prime Factorization is defined as any number that may be expressed as a product of prime numbers that has been said to be prime factorized. Any integer with exactly two factors 1 and the number itself. is said to be a prime number.
Given the number is 650
To determine the greatest perfect square that is a factor of the number 650.
We need to write 650 as the product of its prime factors, which is 650.
⇒ 650 = 2×5×5×13
So the pair is 5×5 which is 5² or 25
Hence, the greatest perfect square that is a factor of 650 is 25

Two women start at the same point. they walk in opposite directions for 3 meters, then turn right and walk another 4 meters. how far apart are they?
The total distance between the two women would simply be the sum of the hypotenuse formed by the triangular path they created.
For each women:
c^2 = a^2 + b^2
c^2 = 3^2 + 4^2
c^2 = 9 + 16
c^2 = 25
c = 5 m
Therefore the distance between the two is:
distance between the two women = 2 * c
distance between the two women = 10 m

Describe the transformation f(x) = √x + 1 − 5 in words. The parent function f(x) = √x has been shifted 1 unit and 5 units.
Answer:
We are given,
The transformed function is [tex]f(x)=\sqrt{x+1}-5[/tex].
So, we can see that,
The parent function is [tex]f(x)=\sqrt{x}[/tex].
Then, we have,
The parent function is translated 1 units to the left to give [tex]\sqrt{x+1}[/tex].
Then, it is translated 5 units downwards to give the function [tex]\sqrt{x+1}-5[/tex].
Hence, we have,
The parent function [tex]f(x)=\sqrt{x}[/tex] is translated 1 unit to the left and 5 units down.The parent function f(x) = √x has been shifted 1 unit left and 5 units down
The parent function of a square root function is represented as:
[tex]f(x) = \sqrt x[/tex]
When the function is shifted 1 unit left, we have the following equation
[tex]f(x) = \sqrt {x + 1}[/tex]
When the function is shifted 5 units down, we have the following equation
[tex]f(x) = \sqrt {x + 1} - 5[/tex]
Hence, the parent function f(x) = √x has been shifted 1 unit left and 5 units down

Amersham station is the highest station in the London Tube at 147 meter above sea level. Waterloo station is the lowest station at 21 meters below sea level. What is the height difference?
Final answer:
The height difference between Amersham station (147 meters above sea level) and Waterloo station (21 meters below sea level) is 168 meters.
Explanation:
To find the height difference between Amersham station, which is the highest station in the London Tube at 147 meters above sea level, and Waterloo station, the lowest at 21 meters below sea level, we simply add the two values together, treating the below sea level as a negative altitude.
147 meters (Amersham altitude above sea level) + (-21 meters) (Waterloo altitude below sea level) = 168 meters.
Therefore, the height difference between Amersham and Waterloo stations is 168 meters.
