Use the formula to evaluate the infinite series. Round to the nearest hundreth if necessary.
zalisa [80]

Answer:

4

Step-by-step explanation:

The first term is the value of the term when n=1. It is 3. The common ratio is is the value being raised to the power of (n-1). It is 1/4. Put these numbers into the formula and do the arithmetic

S = 3/(1 -1/4) = 3/(3/4) = 3·4/3 = 4

The sum is 4.

Mr. Blue's first year salary is $30,000 and it doubles each year. What is the explicit rule for the sequence in simplified form?
vekshin1

Mr. Blue' salary is an illustration of a geometric sequence

  • The explicit rule of Mr. Blue 's salary is an = 30000 * 2^(n - 1)
  • The recursive rule of Mr. Blue's salary is an+1 = 2an; a1 = 30000
<h3 /><h3>How to determine the explicit formula?</h3>

Mr. Blue's salary is a geometric sequence with the following parameters:

First term, a1 = 30000

Rate, r = 2

The explicit rule is calculated as:

an = a1 * r^(n - 1)

This gives

an = 30000 * 2^(n - 1)

<h3>How to determine the recursive formula?</h3>

The common ratio is calculated as:

r = an+1/an

Substitute 2 for r

2 = an+1/an

Cross multiply

an+1 = 2an

Hence, the recursive rule of Mr. Blue's salary is an+1 = 2an; a1 = 30000

Answer:

(6x^2)(x^4 +x^2 + 1)

Step-by-step explanation:

6x^6 + 6x^4 + 6x^2

split it up into parts

6x^6 = (6x^2) * x^4

6x^4 = (6x^2) * x^2

6x^2 = (6x^2) * 1

so you can take out 6x^2 to get

(6x^2)(x^4 +x^2 + 1)

8 identical pens cost £12 work out the cost of 10 of these pens
katen-ka-za [31]

Ok. So, if 8 pens cost £12. Then we would divide £12 by 8. Each pen costs £1.5.

So now we are going to multiply £1.5 and 10. £1.5*10=15.

The total of 10 pens is £15.

I hope this helps, if you need any additional help, just ask. I am here to help you as needed.
