Question

Which combination of transformations can you use to show that one shape is congruent to another?

A. dilations and reflections

B. reflections and stretches

C. rotations and translations

D. reflections, dilations, and translations

E. rotations, translations, and dilationsANSWER -


ANSWER -

The correct answer to this is:

ROTATIONS AND TRANSLATIONS


Reflection and rotation can also be used but since their both grouped with dilations, they can't be used. When dilation is used, the size of the shape is changed and congruence won't be possible anymore . That's why the answer is the first option.

The first three terms of a sequence are given. Round to the nearest thousandth (if
saveliy_v [14]

Answer:

  a7 ≈ 1.068

Step-by-step explanation:

The given sequence has a common ratio, so is a geometric sequence. The formula for a generic term can be used to find the 7th term.

<h3>Sequence</h3>

The first term is 6. The common ratio is ...

  r = (9/2)/6 = (27/8)/(9/2) = 3/4

The n-th term is ...

  an = a1(r^(n-1))

<h3>Application</h3>

The 7th term is ...

  a7 = 6(3/4)^(7-1) = 6(729/4096) = 2187/2048

  a7 ≈ 1.068

Two events, A and B, are disjoint. What is the probability that both A and B will occur at the same time?
solniwko [45]
ANSWER

P(A\cap B)=0

EXPLANATION

If the two events are disjoint, then they are mutually exclusive.

This means that their intersection is zero.

Therefore

n(A\cap B)=0

This implies that,

P(A\cap B)= \frac{n(A\cap B)}{n(U)}

P(A\cap B)= \frac{0}{n(U)} = 0

The probability that the two events will occur together is 0, which means an impossibility.

1/2(y+3)&gt;1/3(4-y) with the steps
lys-0071 [83]

\frac{1}{2(y-3)}>\frac{1}{3(4-y)}=>3(4-y)>2(y-3)

12 - 3y > 2y - 6

12 + 6 > 2y + 3y

18 > 5y

y

y ∈ (-oo, \frac{5}{18})

Last year 12 records in his collection now he has 15 records what is his percent increase of his Collection
Nesterboy [21]

Given that,

Last year record = 12

This year record = 15.

To find,

The percent increase of his Collection.

Solution,

The percent increase in his collection is given by :

\%=\dfrac{\text{final collection-initial collection}}{\text{initial collection}}\times 100\\\\=\dfrac{15-12}{12}\times 100\\\\=25\%

So, the percent increase of his collection is 25%.

After graduating from college, Jane has two job offers to consider. Job A is compensated at $100,000 a year but
vaieri [72.5K]

Answer: (a)  Job A , by approximately $69, 482

\\ (b)  Job A , by approximately $6,867

 \\(c) Job B , by approximately $ 767,362

  \\ (d) Job A

Step-by-step explanation:

JOB B

\\The starting Salary is $ 10,000

Since there is an increment of 25% at the beginning of each new year. The breakdown of the increment is as follow:

\\First year : 125% of $ 10,000 = $12,500

\\Second year : 125% of $ 12,500 = $15,625

\\Third year : 125% of $15,625= $19,531.25

\\Fourth year: 125% of $19,531.25 = $24,414.06

\\Fifth year : 125% of $24,414.06 = $30,517.58

\\Sixth year: 125% of $30,517.58 = $38,147.00

\\Seventh year: 125% of $38,147.00 = $47,683.75

\\Eight year: 125% of $47,683.75 = $59,604.69

\\Ninth year: 125% of $59,604.69 = $74,505.86

\\Tenth year: 125% of $74,505.86 = $93,132.32

\\Following the same procedure:

\\Eleventh year = $116,415.40

\\Twelfth year = $145,519.25

\\Thirteenth year = $181,899.06

\\Fourteenth year = $227,373.82

\\Fifteenth year = $ 284,217.29

\\Sixteenth year = $355,271.61

\\Seventeenth year = $444,089.51

\\Eighteenth year = $555,111.89

\\Nineteenth year = $693,889.86

\\Twentieth year = $867,362.32

\\(a) Following the analysis above, at the beginning of the fifth year Job A will have a greater annual salary

\\Difference: Salary of Job A at the beginning of fifth year remains $ 100,000 while that of Job B resulted into $ 30,517.58, the difference implies

$100,000 - $ 30,517.58 = $69,482

\\(b) At the beginning of tenth year, Job A is still $100,000, Job B resulted into $93,132.32. Job A is still greater by approximately $6,867

\\(c) At the beginning of the twentieth year, the annual salary of A is still $ 100,000 while the annual salary of B is $ 867,362.32. Job B annual salary is greater by approximately $ 767,362

\\(d) If I were in Jane’s shoe I will take Job A and work for few years to gain more experience the look for a job that pays better. Waiting for many years in case of Job B is risky , market situation is uncertainty.
