What are the first four terms of the sequence represented by the expression n(n-2)-3

Answers

Answer:

As per the statement:

Given a sequence:

$a_n = n(n-2)-3$

where, n is the number of terms;

We have to find the first four terms of this sequence:

For n =1

$a_1 = 1(1-2)-3 =1(-1)-3 = -1-3 = -4$

⇒ $a_1 = -4$

For n =2

$a_2= 2(2-2)-3 =2(0)-3 = 0-3 = -3$

⇒ $a_2 = -3$

For n =3

$a_3 = 3(3-2)-3 =3(1)-3 = 3-3 = 0$

⇒ $a_3= 0$

For n =4

$a_4 = 4(4-2)-3 =4(2)-3 = 8-3 = 5$

⇒ $a_4= 5$

Therefore, the first four terms of the sequence are:

-4, -3, 0 , 5

$a_n=n(n-2)-3 \n \na_1=1(1-2)-3=1 * (-1)-3=-1-3=-4 \na_2=2(2-2)-3=2 * 0-3=0-3=-3 \na_3=3(3-2)-3= 3 * 1-3=3-3=0 \na_4=4(4-2)-3=4 * 2 -3 =8-3 =5$

The first four terms are -4, -3, 0, 5.

What percent of the June budget was for babysitting and movies (to the nearest tenth)?

Answers

The monthly expenses are found below:

Mortgage - $752 Tim's Chevron - $23Johnny's Allowance - $8Electric - $176Jenny-babysitting - $12Movie - $14Dry Cleaning - $41Tithe - $85,Credit Card - $150Food - $101Phone - $45Water - $16 Car - $272

Adding all the expenses, will give us a total of $1695.

To get the percent which is allocated for movie and the baby sitting:

Add the amount for the two then divide that to the total then multiply it by 100%
= 12 + 14 / 1695 x 100%
= 26 / 1695 x 100%
= 0.015339233 x 100%

=1.5%
The answer is 1.5%

10x=120 what is x i know this but i will give you guys a chance

Answers

first simplify 10x = 120 then solve 10x = 120 to solving for variable 'x' move all terms containing x to the left, all other terms to the right. then divide each side by '10'. x = 12 is ur answer ^-^ hope this helps

Solutions

10x=120

1) Divide both sides by 10 to isolate variable x

x = 120 ÷ 10

2) Simplify 120 ÷ 10 to 12

x = 12
