From the given question, the required answer is option D. It can be deduced that: Reflect ΔECD over segment AC. This establishes that ∠ACB ≅ ∠E'C'D'. Then, (translate point E' to point A). This establishes that (∠D'E'C' ≅ ∠BAC). Therefore, ΔACB ~ ΔECD by the AA similarity postulate.

Rigid transformation is a process of resizing a given shape or figure. This can be done by either increasing or decreasing its dimensions (size) or changing its orientation. Some of the methods required in rigid transformation are: reflection, translation, rotation etc.

From the given question,

if ΔECD is first reflected over (turned about) segment AC, it would be deduced that m∠ACB ≅ m∠E'C'D' = [tex]90^{o}[/tex](right angle principle).

Then, the next process is to translate (extend) point E' to point A, so that m∠D'E'C' ≅ m∠BAC.

This would also ensure that m∠E'D'C' ≅ m∠ABC due to the translation.

This implies that ΔACB ~ ΔECD by the AA similarity postulate.

Therefore, performing reflection and translation operations on ΔECD step-wisely can be used to prove that ΔACB ~ ΔECD by the AA similarity postulate.

Answer:

$13,400

Step-by-step explanation:

We will first have to take account of the commuting cost, years at school, and total cost of tuition and books

It would cost $5,500 per year, she is studying at the school for 2 years, we will multiply 5,500 by 2

$5,500 * 2

= $11,000

The cost of commuting per month will be multiplied by 12 to represent a year and another 2 for two years

$100 * 12 * 2

= $2400

We all these together for the total cost of her education

$11,000 + $2,400

= $13,400

Answer:

RS 146189.8

Step-by-step explanation:

let the price before tax be p

hence the final amount paid (i.e the actual bill)

= price before tax + tax

= p + (0.13% of p)   (convert percentage into fraction)

= p + [ (0.13/100) x  p] ---------------(eq 1)

we are given that the tax (i.e VAT) = 189.80

hence,

[ (0.13/100) x  p] = 189.8

0.13p = (100)(189.8)

p = (100)(189.8) / 0.13

p = 146000

hence our eq 1 above becomes:

p + [ (0.13/100) x  p]

= 146000 + 189.8

= 146189.8

Rules for simplifing variables which may be raised to a power:

   (1) variables with no exponent stay inside the radical

   (2) variables raised to power 1 or (-1) stay inside the radical

   (3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:

      (3.1) sqrt(x8)=x4

     (3.2) sqrt(x-6)=x-3

    (4) variables raised to an odd exponent which is  >2  or  <(-2) , examples:

      (4.1) sqrt(x5)=x2•sqrt(x)

     (4.2) sqrt(x-7)=x-3•sqrt(x-1)

If I'm understanding the question right it's -.05

Step-by-step explanation:

(2x - 3) = 2

There is no more simplifying to be done in the parentheses.

2x - 3 = 2

Subtract 3 on each side to get the x value by itself.

2x = -1

Divide each side by 2 so the x is by itself.

x = -.05

Answer:

2/5

Step-by-step explanation:

The answer is common sense.

The probability that no two consecutive flips have the same result is [tex]\frac{1}{16}[/tex].

If a coin is flipped then there are two possible outcomes Head(H) and Tail (T).

So each flip can have 2 possible outcomes. It means 5 flips have [tex]2^5=32[/tex] possible outcomes.

Among these 32 outcomes only 2 outcomes : HTHTH and THTHT have "no two consecutive flips have the same result".

So the probability that no two consecutive flips have the same result is = [tex]\frac{2}{32} =\frac{1}{16}[/tex].

Answer:

The series has 7 terms

[tex]\displaystyle S_7=\frac{4372}{243}[/tex]

Step-by-step explanation:

Geometric Series

In the geometric series, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.

We are given the series:

-12, -4, -4/3, ..., -4/243

We can find the common ratio by dividing one term by the previous term:

[tex]\displaystyle r=\frac{-4}{-12}[/tex]

Simplifying:

[tex]\displaystyle r=\frac{1}{3}[/tex]

Sum of terms: Given a geometric series with first term a1 and common ratio r, the sum of n terms is:

[tex]\displaystyle S_n=a_1\frac{1-r^n}{1-r}[/tex]

We need to find how many terms the series has. Using the explicit formula of a geometric series:

[tex]a_n=a_1\cdot r^{n-1}[/tex]

The last term is an=-4/243 and the first term is a1=-12. Solving for n:

[tex]\displaystyle n= \frac{\log(a_n/a_1)}{\log r}+1[/tex]

[tex]\displaystyle \frac{\log(-4/243/-12)}{\log 1/3}+1[/tex]

[tex]\displaystyle \frac{\log(1/729)}{\log 1/3}+1[/tex]

n=7

The series has 7 terms

Thus, the sum of the 7 terms of the series is:

[tex]\displaystyle S_7=-12\frac{1-(1/3)^7}{1-(1/3)}[/tex]

[tex]\mathbf{\displaystyle S_7=\frac{4372}{243}}[/tex]

Answer:

-5v+3v = -2v

k-2-6+5k = 6k - 8

Step-by-step explanation:

For -5v+3v

-5 + 3 = -2

V is left so it's -2v

For k-2-6+5k

k + 5k - 2 - 6

6k - 2 - 6

6k - 8

1) -5v + 3v

= -2v

2) k - 2 - 6 + 5k

First take all like terms (everything with the same letters):

k + 5k = 6k

6k - 2 - 6

-2 - 6

= -8

6k - 8

Answer:

The quadratic x2 − 5x + 6 factors as (x − 2)(x − 3). Hence the equation x2 − 5x + 6 = 0

has solutions x = 2 and x = 3.

Similarly we can factor the cubic x3 − 6x2 + 11x − 6 as (x − 1)(x − 2)(x − 3), which enables us to show that the solutions of x3 − 6x2 + 11x − 6 = 0 are x = 1, x = 2 or x = 3. In this module we will see how to arrive at this factorisation.

Polynomials in many respects behave like whole numbers or the integers. We can add, subtract and multiply two or more polynomials together to obtain another polynomial. Just as we can divide one whole number by another, producing a quotient and remainder, we can divide one polynomial by another and obtain a quotient and remainder, which are also polynomials.

A quadratic equation of the form ax2 + bx + c has either 0, 1 or 2 solutions, depending on whether the discriminant is negative, zero or positive. The number of solutions of the this equation assisted us in drawing the graph of the quadratic function y = ax2 + bx + c. Similarly, information about the roots of a polynomial equation enables us to give a rough sketch of the corresponding polynomial function.

As well as being intrinsically interesting objects, polynomials have important applications in the real world. One such application to error-correcting codes is discussed in the Appendix to this module.

Answer:

C

Step-by-step explanation:

We are given that:

[tex]a(x+b)<c[/tex]

Where a < 0.

To solve for x, we can divide both sides by a.

Since a < 0, a is negative. Hence, we must flip the inequality sign. This yields:

[tex]\displaystyle x + b > \frac{c}{a}[/tex]

Subtract b from both sides. Hence:

[tex]\displaystyle x>\frac{c}{a}-b[/tex]

In conclusion, our answer is C.
