Answers

Answer 1

Answer: 19.625 cm (Formula is 2πr)

Steps: 1.) 3.14 * 12.5 = 39.25

          2.) 39.25 * 2 = 78.5

          3.) 78.5  /  4  = 19.625 (using the 4 because the area is a fourth of a whole circle)

10. An arithmetic sequence has this recursive formula. What is the explicit formula?​

Answers

Answer:

[tex]a_{n}=45-3n[/tex]

Step-by-step explanation:

Method 1:

Arithmetic sequence is in the form

[tex]a_{n} =a_{1} +(n-1)d\\[/tex]

d is the common difference, can be found by:

[tex]d=a_{n}-a_{n-1}=-3[/tex]

Subtituting the [tex]a_{1}[/tex] and [tex]d[/tex]

You get:

[tex]a_{n}=42+(-3)(n-1)=45-3n[/tex]

Method 2 (Mathematical induction):

Assume it is in form [tex]a_{n}=45-3n[/tex]

Base step: [tex]a_{1} =45-3(1)=42[/tex]

Inducive hypophesis: [tex]a_{n}=45-3n[/tex]

GIven: [tex]a_{n+1} =a_{n}-3[/tex]

[tex]a_{n+1}=45-3n-3=45-3(n+1)[/tex]

Proved by mathematical induction

[tex]a_{n}=45-3n[/tex]

Answers

Answer:

Step-by-step explanation:

7x + 9 = 58

     -9    -9      Subtract 9 from both sides

7x = 49

/7     /7           Divide both sides by 7

x = 7 (this is an apporximation)

Answer:

7

Step-by-step explanation:

1st you need to subtract 9 from both sides like this: 7x+9-9=58-9. and you'll get 7x=49. Then, divide by 7 on both sides like this: 7x/7=49/7. and you'll get x=7.
