Is it possible for a segment to have more than one bisector? Explain your reasoning.

Answers

Yes.

A bisector of a line segment is a line which divides the line segment into two equal parts.
A bisector of a line can divide the line in many different ways forming different angles.
A bisector is said to be a perpendicular bisector if the angle at the intersection of the two lines is 90 degrees.
But, there are several other bisectors that are not perpendicular bisectors.

Therefore, it is possible for a segment to have more than one bisector.

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

A ladder is leaning against a wall. The top of the ladder is 9 feet above the ground. If the bottom of the ladder is moved 3 feet farther from the wall, the ladder will be lying flat on the ground, still touching the wall. How long, in feet, is the ladder?

Answers

So technically they are asking you to find the hypotenuse of a right angle triangle the height is 9ft and the length is 3ft so the formula is
A² +b²=c²

the a² and B² Being the height and length and label the third side c²

so..
9²+3²=c²
9×9+3×3=c²
81+9=c²
40=c²
√40=√c²
6.32=c
therefore the ladder is 6.32

well i think that is how you answer

check the picture below

[tex]\bf \textit{using the pythagorean theorem}\\\\ r^2=x^2+y^2\implies r=\sqrt{x^2+y^2} \\\\\\ r=\sqrt{x^2+9^2}\implies r=\sqrt{x^2+81}\impliedby \textit{leaning ladder} \\\\\\ r=\sqrt{(x+3)^2+0^2}\implies r=\sqrt{(x+3)^2}\impliedby \textit{flat ladder}\\\\ -------------------------------\\\\[/tex]

[tex]\bf \sqrt{x^2+81}=\sqrt{(x+3)^2}\implies x^2+81=(x+3)^2 \\\\\\ x^2+81=x^2+6x+9\implies 81-9=6x\implies 72=6x\implies \cfrac{72}{6}=x \\\\\\ \boxed{12=x}\\\\ -------------------------------\\\\ \textit{now, the ladder "r" is }\sqrt{(x+3)^2}\implies \sqrt{(12+3)^2}\implies 15[/tex]

Write the standard form of the line that contains a y-intercept of -3 and passes through the point (3, 0). Include your work in your final answer. Type your answer in the box provided or use the upload option to submit your solution.

Answers

We have two points, (3,0) and (0,-3).  So we can find the slope of the line:

m=(y2-y1)/(x2-x1)

m=(-3-0)/(0-3)

m=-3/-3

m=1  so far for the line y=mx+b we have:

y=x+b, b is the y intercept which we were told is -3 so

y=x-3

The above is called the slope-intercept form of a line, y=mx+b, the standard form of a line is ax+by=c, so we need to get both variables on one side of the equation..

y=x-3  subtract x from both sides

-x+y=-3

While the above may be acceptable to some, technically the coefficient of x should be expressed as a positive value, so we should divide the above "solution" by -1 to get:

x-y=3
Final answer:

The equation of the line in standard form that has a y-intercept of -3 and passes through the point (3, 0) is y = x - 3.

Explanation:

The standard form of a line can be found using the formula y = mx +b, where 'm' is the slope and 'b' is the y-intercept. The y-intercept in this problem is -3, but we need to find the slope to complete the standard form of the line. Since our line passes through the point (3,0) and (0,-3), the slope, m, can be found by using the formula (y2-y1)/(x2-x1), which gives us a slope of 1. So the equation of our line in standard form is y = x - 3.

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

Answers

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.

Final answer:

To find the solutions of the equation 4x^4 - 4x^2 = 8, we can rearrange the equation and solve the resulting quadratic equation. The solutions are x = ±√2.

Explanation:

To find the solutions of the equation 4x^4 - 4x^2 = 8, we can rearrange the equation to get 4x^4 - 4x^2 - 8 = 0. This is a quadratic equation in terms of x^2. We can solve this quadratic equation by factoring or by using the quadratic formula.

Factoring the equation, we get (2x^2 - 4)(2x^2 + 2) = 0. Setting each factor equal to zero, we have 2x^2 - 4 = 0 and 2x^2 + 2 = 0.

Solving each equation separately, we get x^2 = 2 and x^2 = -1. Taking the square root of both sides, we get x = ±√2 and x = ±i. Therefore, the solutions of the original equation are x = ±√2.

Step-by-step explanation:

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)

Answers

The formula is
A=p (1+r/k)^kt
A future value 3000
P present value 150
R interest rate 0.025
T time?
3000=150 (1+0.025/12)^12t
Solve for t
3000/150=(1+0.025/12)^12t
Take the log
Log (3000/150)=log (1+0.025/12)×12t
12t=Log (3000/150)÷log (1+0.025/12)
T=(log(3,000÷150)÷log(1+0.025÷12))÷12
T=119.95 years

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

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?

Answers

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.

How many equations are needed to solve for 1 unknown variable?

Answers

The number of equation/s that are needed in order to solve the problem is equal to the number of the varying variables involved. In this regard, we would say that to solve for 1 unknown variable, only 1 equation is needed. 

For number of variables greater than 1, as stated above, the number of equations should be equal to that number. However, it has to be noted that the equations should be independent and not the multiplicative of another. 

For the concept of multiplicity,

x + y = 0 and 2x + 2y = 0 are just the same equations.
