Answer:

<h2><em>y = |x - 5| + 2</em></h2>

Step-by-step explanation:

f(x) + n - <em>shift up n units</em>

f(x) - n - <em>shift down n units</em>

f(x + n) - <em>shift left n units</em>

f(x - n) - <em>shift right n units</em>

f(-x) -<em> reflect about the y-axis</em>

-f(x) - <em>reflect about the x-axis</em>

<em />

<em>The graph of the function </em><em>y = |x| </em><em>has a vertex in the origin </em><em>(0, 0).</em>

<em>The vertex of the given graph is in the point </em><em>(5, 2) - </em>incorrectly marked coordinates on the graph (2, 5).

<h3>Conclusion:</h3>

<em>The graph of the function y = |x| has been shifted 5 units to the right and 2 units up.</em>

<em>Therefore:</em>

<em>y = |x - 5| + 2</em>

Suppose a city with population 500,000 has been growing at a rate of ​7% per year. If this rate​ continues, find the population
krok68 [10]

Answer:

2,070,281

Step-by-step explanation:

let x = number of years

let y = population

Given:

  • initial population = 500000
  • rate of increase = 7%

y = 500000 × 1.07^x

when x = 21:

y = 500000 × 1.07^(21) = 2070281.187... = 2,070,281

The table displays the frequency of scores for a calculus class on an exam. The mean of the exam scores is 3.5. Score 1 2 3 4 5
vladimir1956 [14]

Answer:

f=11

Mode=4

Median=4

Explanation:

We are given that

a.Mean of the exam score,\bar x=3.5

Score(x)   frequency   C.F

1                  1                 1

2                  3                4

3                  f                 15(4+f=4+11)

4                  13               28

5                   4               32

\sum f_i=1+3+f+13+4=21+f

\sum f_ix_i=1(1)+2(3)+3(f)+4(13)+5(4)=1+6+3f+52+20=79+3f

(\bar x)=\frac{\sum f_ix_i}{\sum f_i}

Using the formula

3.5=\frac{79+3f}{21+f}

73.5+3.5f=79+3f

3.5f-3f=79-73.5

0.5f=5.5

f=\frac{5.5}{0.5}=11

b.Mode:The number which is repeat most times .

4 repeat most times

Hence, mode of all exam scores=4

N=32

N is even

Median=\frac{(\frac{n}{2})^{th}+(\frac{n}{2}+1)^{th}}{2}

Median=\frac{16th+17th}{2}=\frac{4+4}{2}=\frac{8}{2}=4
