Write a recursive formula for each explicit formula

Crazy boy [7]

Answer:

38. $a_1=107,\ a_n=a_{n-1}-1$

40. $a_1=87,\ a_n=a_{n-1}+52$

Step-by-step explanation:

38. <u>Given explicit formula:</u>

$a_n=108-n$

When $n=1,$ then $a_1=108-1=107$

When $n=2,$ then $a_2=108-2=106$

When $n=3,$ then $a_3=108-3=105$

When $n=4,$ then $a_4=108-4=104$

and so on

You can see that each next number is 1 less than previous number, so the recursive formula is

$a_n=a_{n-1}-1$

40. <u>Given explicit formula:</u>

$a_n=35+52n$

When $n=1,$ then $a_1=35+52\cdot 1=87$

When $n=2,$ then $a_2=35+52\cdot 2=139$

When $n=3,$ then $a_3=35+52\cdot 3=191$

When $n=4,$ then $a_4=35+52\cdot 4=243$

and so on

You can see that each next number is 52 more than previous number, so the recursive formula is

$a_n=a_{n-1}+52$

The number a is smaller than the number b by 1/5 of b. By what part of a is b bigger than a?

Ira Lisetskai [31]

Answer:

The number b is bigger than the number a by $\dfrac{1}{4}$ of a.

Step-by-step explanation:

1. If the number a is smaller than the number b by 1/5 of b, then

$a+\dfrac{1}{5}b=b.$

Thus,

$a=b-\dfrac{1}{5}b=\dfrac{4}{5}b,\\ \\b=\dfrac{5}{4}a.$

2. Consider the expression $b=\dfrac{5}{4}a:$

$b=\dfrac{5}{4}a=\dfrac{4}{4}a+\dfrac{1}{4}a=a+\dfrac{1}{4}a.$

This gives you that the number b is bigger than the number a by $\dfrac{1}{4}$ of a.

Help asap thank you!!!!!

viktelen [127]

Answer:

A = 120

C = 45

Step-by-step explanation:

(12x + 12) + 15 + (3x + 18) = 180

(12x + 3x) + (12 + 15 + 18) = 180

15x + 45 = 180

15x = 180 - 45

15x = 135

x = 135/15

x = 9

A = 12x + 12 = 12(9) + 12 = 108 + 12 = 120

C = 3x + 18 = 3(9) + 18 = 27 + 18 = 45
