Write down in terms of n an expression for the nth term of the following sequence 12,10,8,6,4

Answers

Answer 1

Answer:

n-2

Step-by-step explanation:

Answer 2
there is an obvious pattern. Such sequences can be expressed in terms of the nth term of the sequence. In this case, the nth term = 2n. To find the 1st term, put n = 1 into the formula, to find the 4th term, replace the n's by 4's: 4th term = 2 × 4 = 8. The common difference is -2, so the formula for the nth term is 12-2(n-1).

This can be written 12-2n+2=14-2n, so that when n=1, the 1st term is 14-2=12.

The 5th term is 14-10=4; the 6th is 14-12=2. And so on. This is the formula The expression for the total number of tiles in the nth term is the sum of the areas of the rectangles, n2 + n(n – 1) + 2, which can be simpli- fied to 2n2 – n + 2. quadratic sequences with visual models these are just examples: The nth odd number is given by the formula 2*n-1.
In linear sequences only, the 'nth-term rule' gives the value of any term in that sequence at position 'n'. It is written as 'xn ± y' where x = the constant difference between term values and y is a particular number. The rule allows you to work out the terms of a sequence. An arithmetic progression is a sequence where each term is a certain number larger than the previous term. The terms in the sequence are said to increase by a common difference, d. For example: 3, 5, 7, 9, 11, is an arithmetic progression where d = 2. The nth term of this sequence is 2n + 1.

The fraction that is equivalent to 4/7 among the given set of fractions is 8/14

Equivalent of fractions

From the question, we are to determine the fraction that is equivalent to 4/7

To determine this, we will reduce each of the given fractions to their lowest terms where possible

For 6/9

Dividing both the numerator and denominator by 3, we get

2/3

∴ 6/9 is not equivalent to 4/7

For 8/14

Dividing both the numerator and the denominator by 2, we get

4/7

∴ 8/14 is equivalent to 4/7

For 2/3

This is the lowest form of this fraction and it is not equivalent to 4/7

For 8/21

This is the lowest form of this fraction and it is not equivalent to 4/7

Hence, the fraction that is equivalent to 4/7 among the given set of fractions is 8/14.

Ingrid's curtain company is making curtains for a local hotel. She wants each curtain to be 36 inches long. At the fabric store, fabric is sold by the foot. If Ingrid's curtain company wants to make 64 curtains, how many feet of fabric will she need? 1 inch = 1 12 foot I just don't get it

Answers

Answer:

192 ft

Step-by-step explanation:

Number of curtains = 64

Length of each curtains = 36 inches

Total length of curtains = Number of curtains × Length of each curtains

= 64 × 36 inches

= 2,304 inches

1 inch = 1/12 foot

2,304 inches = 2,304 / 12 ft

2,304 inches = 192 ft

She will need 192 ft of the fabric to make 64 curtains each of length 36 inches

Okay, I haven't done this a long time however I believe with this you have to solve the equation by doing substitution.

Step-by-step explanation:

so, if f (x) equals 13, you replace the x in the equation to 13.

f(x)=-2x+5

f(x)=-2(13)+5

f(x)=26+5

f(x)=31

Kiaya has to have at least $100 in her checking account to avoid a fee from the bank. She has $376 in her account now. Each week, she makes a $25 withdrawal. For how many weeks can she make this withdrawal and avoid a fee?

Answers

Answer:

$500 a week

Step-by-step explanation:

Hope I can help.

Kiaya can make a $25 withdrawal for 11 weeks without incurring a fee.

What is the division operation?

In mathematics, divides left-hand operands into right-hand operands in the division operation.

Kiaya needs to have at least $100 in her checking account to avoid a fee from the bank. She has $376 in her account now, so she can make $376 - $100 = $276 worth of withdrawals before she will be charged a fee.

Each week, she makes a $25 withdrawal.

To determine the number of weeks she can make this withdrawal before being charged a fee, we divide the total amount she can withdraw ($276) by the amount she withdraws each week ($25).

So, Kiaya can make $276 / $25 = 11 withdrawals before she will be charged a fee.

Therefore, she can make a $25 withdrawal for 11 weeks without incurring a fee.
