Your Teacher is wondering if the absolute value of a number can ever be negative. Is she correct? Why or Why not? Use specific examples and sound mathematical reasoning to support your answer

Answers

Answer 1
The absolute value of a number can never be negative; it is always positive. It is a distance past 0. Therefore it cannot be in the negatives.
Answer 2
Absolute value can never be negative. The definition of absolute value is the distance a number is from 0 expressed as a numerical value. You can’t have negative distance therefore you can’t have negative absolute value.

(for example if you walk backwards, you’re still walking forwards in a given direction so that wouldn’t be negative distance traveled.)

Answer:

The answer is 402.

Step-by-step explanation:

First thing to do is substitute the variables.

6(3)^2+(9(8)-2)+8

Now, multiply and subtract what is in the parenthesis.

6(3)^2+(72-2)+8

6(3)^2+70+8

Now, multiply once again.

A price increases from $50 to $120. What is the percentage change?

Answers

Answer: 140%

Step-by-step explanation:

From the question, we are informed that price increases from $50 to $120. The percentage change will be:

= (New price - Old price)/Old price × 100

= (120 - 50)/50 × 100

= 70/50 × 100

= 1.4 × 100

= 140%

What is the value of x in the figure below? In this diagram, AABD - ACAD.

Answers

Answer:  E.  sqrt(45)

===================================================

The right triangles are similar, allowing us to form the proportion below

BD/AD = AD/DC

5/AD = AD/9 .... substitution

5*9 = (AD)*(AD) .... cross multiply

45 = (AD)^2

(AD)^2 = 45

AD = sqrt(45) ... apply square root

We could simplify but your teacher has decided not to. If you want to simplify, then

AD = sqrt(45)

AD = sqrt(9*5)

AD = sqrt(9)*sqrt(5)

AD = 3*sqrt(5)

--------

Segment AD is the geometric mean of BD and DC.

AD = sqrt(BD*DC)

which is the result of solving BD/AD = AD/DC for AD

So,

AD = sqrt(BD*DC)

AD = sqrt(5*9)

AD = sqrt(45)

First question’s answer:
Since angle A = Angle E
Therefore, Angle B (=x) = Angle D
B = X
D = 66
By replacement B = X = D = 66
So, B = 66
Answer is (A)
-------------
Second question’s answer:
Since Angle F = 63 & Angle C = (3X + 3)
Therefore, Angle F = Angle C
63 = (3X + 3)
Add (-3) into each side
63 + (-3) = (3X + 3) -3
3x + -3x = 0
63 + -3x = 3 + 0
63 + -3x = 3
Now, Add '-63' to each side of the equation
63 + -63 + -3x = 3 + -63
63 + -63 = 0
0 + -3x = 3 + -63
-3x = 3 + -63
3 + -63 = -60
-3x = -60
Divide each side by '-3'
x = 20
So, X angle value is 20 (X=20)
The answer is (C)

Answers

Answer:

x = 6 or x = -2

Step-by-step explanation:

Solve for x:

2 x^2 - 8 x - 24 = 0

The left hand side factors into a product with three terms:

2 (x - 6) (x + 2) = 0

Divide both sides by 2:

(x - 6) (x + 2) = 0

Split into two equations:

x - 6 = 0 or x + 2 = 0

Add 6 to both sides:

x = 6 or x + 2 = 0

Subtract 2 from both sides:

Answer: x = 6 or x = -2

Daniel wants to open an account to purchase a new computer. He was able to put $750 into an account that pays him 8.5% interest. The cost of the computer he wants is $1,150.00. How long will he have to wait to withdraw the money?

Answers

Answer:

Daniel has to wait around 5.24 years to withdraw the money.

Step-by-step explanation:

We are given that Daniel wants to open an account to purchase a new computer. He was able to put $750 into an account that pays him 8.5% interest. The cost of the computer he wants is $1,150.00.

Let the Principal sum of money be represented by 'P'.

The rate of interest be represented by 'R'.

The time period be represented by 'T'.

The final amount of money be represented by 'A'.

Assuming the interest given is compound interest.

So, the formula for calculating the amount of money is given by;

                          [tex]\text{A} = \text{P} \times (1-\text{R})^{\text{T}}[/tex]

Here, A = $1,150, P = $750, R = 8.5% and let the time he have to wait to withdraw the money be 'n'.

So, putting these values in the above formula we get;

[tex]\text{A} = \text{P} \times (1+\text{R})^{\text{T}}[/tex]

[tex]\text{\$1,150} = \text{750} \times (1+\text{0.085})^{\text{n}}[/tex]

[tex](1+\text{0.085})^{\text{n}} = \frac{\$1,150}{\$750}[/tex]

[tex](1+\text{0.085})^{\text{n}} = 1.533[/tex]

Taking log on both sides;

[tex]\text{n} \times ln(1+\text{0.085}) = ln(1.533)[/tex]

[tex]n = \frac{ ln(1.533)}{ ln(1.085)}[/tex]

n = 5.24 years

Hence, he has to wait around 5.24 years to withdraw the money.

Ao cobrar uma falta em um jogo de futebol, uma jogador imprime à bola a uma velocidade de 43,2 km/h. Sabendo que a bola gasta 3 s até atingir as redes, determine a distância percorrida? A)16m B)36m C) 30m D)12m E) 24m

Answers

Answer:

B

Step-by-step explanation:

Nesta questão, estamos interessados ​​em calcular a distância percorrida se um jogador correr a uma velocidade de 43,2 km / h por 3 segundos.

Matematicamente; a distância percorrida = velocidade * tempo

O problema que temos aqui é que nossas unidades não são consistentes.

A melhor maneira de fazer isso é ter unidades consistentes em metros por segundos e segundos, pois nossa resposta está em metros.

Portanto, a conversão que precisamos fazer aqui é converter 43,2 km / h em metros por segundo Matematicamente, sabemos que existem 1000 m em um quilômetro.

Da mesma forma, uma vez que 60 segundos fazem um minuto e 60 minutos fazem uma hora, o número de segundos em uma hora é 60 * 60 = 3.600 segundos

Assim, convertendo 43,2 km / h em m / s, temos; (43,2 * 1000) / 3600 = 12 m / s

Portanto, a distância percorrida em metros seria agora; velocidade em m / s * tempo em segundos = 12 m / s * 3 segundos = 36 m

Binomial (x – 6) and trinomial (–2x2 + x + 9) are the factors of which of the following polynomials?

Answers

Answer:

The polynomial is -2x³ + 13x² + 3x - 54.

Step-by-step explanation:

The binomial expression is: (x - 6)

The trinomial expression is: (-2x² + x + 9)

Multiply the two expressions to determine the resulting polynomial as follows:

[tex](x-6)(-2x^{2}+x+9)=x(-2x^{2}+x+9)-6(-2x^{2}+x+9)[/tex]

                                   [tex]=-2x^{3}+x^{2}+9x+12x^{2}-6x-54\\=-2x^{3}+13x^{2}+3x-54[/tex]

Thus, the polynomial is -2x³ + 13x² + 3x - 54.

Tyrone claims that the first step to simplfy this expression is to raise the numerator and denominator to the third power. Alisha claims that the first step to simplfy is to apply the qoutient of powers. Who is correct? Explain.

Answers

Answer:

Alisha's approach is simpler and less complicated

Step-by-step explanation:

Given:

(m^2*n^-3) / (m^6*n^-1)

Tyrone's approach.

(m^2*n^-3) / (m^6*n^-1)

(m^2*n^-3)^3 / (m^6*n^-1)^3

You can find the cube root of both the numerator and denominator in order to eliminate the third power

3√((m^2*n^-3)^3 / 3√(m^6*n^-1)^3

This will take us back to the original expression

(m^2*n^-3) / (m^6*n^-1)

= m^(2-6)*n^(-3+1)

= m^-4*n^-2

= 1/(m^4*n^2)

Alisha's approach.

(m^2*n^-3)/(m^6*n^-1)

= m^(2-6)*n^(-3+1)

= m^-4*n^-2

= 1/(m^4*n^2)

The approach of both of them are correct, however, Tyrone's approach will make the expression more complicated but they would still arrive at the same answer. 1/(m^4*n^2)

Explanation:

The two given points have x coordinates of x = 6 each. They add to 6+6 = 12. Divide this in half to get 12/2 = 6. Since the x coordinates were both the same, the midpoint x coordinate is the same as well.

The y coordinates are a bit more interesting. Add them up to get -5+1 = -4. Then cut this in half to get -4/2 = -2. The y coordinate of the midpoint is -2.

Nine years ago, Tarah opened a savings account with her bank. She started with a balance of $359 and has not made any withdrawals or deposits since then. If her interest rate is 8% each year, how much interest has accrued using simple interest? Total Interest = $ What is Tarah's new total balance? New Balance Total = $

Answers

Answer:

Total- 617.48       Interest- 258.48

Step-by-step explanation:

First, we need to find out what 8% of 359 is.

.08 times 359 = 28.72. This is how much interest is gained in a year. Since she waited 9 years, we multiply 28.72  by 9 and get 258.48. This is the total interest.

Now we just add 258.48 and 359 to get 617.48.

Answer:

617.48

Step-by-step explanation:

SI = P x R x T / 100

SI = Simple Interest

P = Principal

R = Rate

T = Time

SI = 359 x 9 x 8 / 100

=> SI = 2872 x 9 /100

=> SI = 25848 /100

=> SI = 258.48

New Balance = Principal + Simple Interest

=> New Balance = 359 + 258.48

=> New Balance = 617.48
