Write a function rule for the following arithmetic sequence and use it to find the 224th term. Show your work.
zavuch27 [327]

Answer:

671  is the 224th term of the given series

Step-by-step explanation:

The given sequence is

2,5,8,11....

First term that is 2

common difference that is 3

we have to find 224th term

That is n =224

using a_n=a+(n-1)d

a_{224}=2+(224-1)3

On solving the above equation we get

a_{224}=671

Hence, 224th term of the given series is 671

Pls help me, cause I don't understand one bit of it at all​
topjm [15]

Answer:

I promise you this is easier than it looks, just bare with me.

You have to order these numbers from the smallest to the biggest. Now before we do this, we wanna make the fractions and mixed numbers decimals to make this easier.

5 8/11

Convert the fraction to a decimal: Divide the numerator by the denominator.  (8 divide by 11).

Add this decimal number to the whole number part of the mixed number. (0.72 plus 5)

It would be 5.72

Now 57/10

The same steps as the last one, but since it isn't a mixed number you don't add anything. (57 divided by 10)

It would be 5.7

Now we have to order them from least to greatest. How do we figure that out? Well lets list the numbers that we have now:

5.72

5.7

5.67

5.726

Now since they all have the same whole number, we just have to look at the numbers after the decimal.  Well the least number we have here is "7". Then it would be 67, then 72, then 726.

So the answer would be from least to greatest:

5.7

5.67

5.72

5.726

I hope this helps..sorry if I took so long I wanted to make sure I explained this as good as I can so you don't keep struggling. Good luck, take care <3

Have a good night/day (:! Much love!

Enter the values for the highlighted variables that show how to subtract the rational expressions correctly:
LenKa [72]

Answer:

a = 6

x^2 + 6x is equal to x(x+6)

b=2

Denominator and numerator of the first term are multiplied by x. 

c=6

Second term is multiplied by (x-6)/(x-6)

d=2

Now that they have the same denominator, the two terms are combined. 2 is the coefficient of the first term

e=6

In the same way as d is carried over from b, e is carried over from c. 

f = 6

2x - x + 6 = x + 6

g = 1 

We factor out the (x+6) from the numerator and denominator
