find the sum of the series. [infinity] (−1)n 2nx8n n! n = 0

Answers

Answer 1

The sum of the series is e⁻²ˣ⁸.

The sum of the series is (-1)⁰ 2⁰ x⁰ 0! + (-1)¹ 2¹ x⁸ 1! + (-1)² 2² x¹⁶ 2! + ... which simplifies to ∑[infinity] (-1)ⁿ (2x⁸)ⁿ/(n!). Using the formula for the Maclaurin series of e⁻ˣ, this can be rewritten as e⁻²ˣ⁸.

The series can be rewritten using sigma notation as ∑[infinity] (-1)ⁿ (2x⁸)ⁿ/(n!). To find the sum, we need to simplify this expression. We can recognize that this expression is similar to the Maclaurin series of e⁻ˣ, which is ∑[infinity] (-1)ⁿ xⁿ/n!.

By comparing the two series, we can see that the given series is simply the Maclaurin series of e⁻²ˣ⁸. Therefore, the sum of the series is e⁻²ˣ⁸. This is a useful result, as it provides a way to find the sum of the given series without having to compute each term separately.

HELP! Please answer fast How many terms are in the geometric series 0.4 + 1.2 + 3.6 + ... + 7,873.2?

Answers

Answer:

10 terms. I think you should check the explanation :)

Step-by-step explanation:

0.4 + 1.2 + 3.6 + ... + 7,873.2?

So I figured that you have to multiply the terms by three to get the next term.

0.4 * 3 = 1.2

1.2 * 3 = 3.6

But, I know it will takes us a really long time to get to 7,873.2, so what I will do is jump 3 sequences.

So if I multiply by 3 to get the next term, I'll multiply by 9 to get the next two terms because 3 * 3 is 9.

So to jump three times, I will multiply by 27 to get the next three terms because 3 * 3 * 3 is 27.

0.4 + 1.2 + 3.6 + ...

3.6 * 27 = 97.2

0.4 + 1.2 + 3.6 + ..., ..., 97.2, ...

97.2 * 27 = 2624.4

0.4 + 1.2 + 3.6 + ..., ..., 97.2, ..., ..., 2624.4, ...

Since we are getting close, I'm going to go back to multiply by 3.

2624.3 * 3 = 7873.2

0.4 + 1.2 + 3.6 + ..., ..., 97.2, ..., ..., 2624.4, 7873.2

Now that we have reached 7873.2, we will now count the terms (count the sets of three dots as terms too).

There are 10 terms in the geometric sequence.

Cándido normally pays $875 for bodily injury and property damage insurance. His insurance company increases premiums by 150% for 1 accident, 200% for 2-3 accidents, and 250% for 4 accidents. Find his premium for the year after he has three accidents to the nearest dollar.

Answers

Answer:

$1,700.

Step-by-step explanation:

Since Cándido normally pays $ 875 for bodily injury and property damage insurance, and his insurance company increases premiums by 150% for 1 accident, 200% for 2-3 accidents, and 250% for 4 accidents, to find his premium for the year after he has three accidents to the nearest dollar, the following calculation must be performed:

875 x 200 / 100 = X

875 x 2 = X

1,700 = X

Therefore, his premium for the year after he has three accidents is $1,700.

Answer:

premium = $ 875

increase 200%

875 * 200 / 100

=$1750

Barry wants to make a drawing that is 1/2 the size of the original. If a tree in the original drawing is 11 inches tall and 5 inches wide,

Answers

Answer:

Barry's drawing is  5.5 in  tall and 2.5 in wide.

Step-by-step explanation:

We are given that

Height of tree, h=11 in

Width of tree, b=5 in

We have to find the size of the original.

Size of drawing is 1/2 size of the original

Therefore,

Height of drawing, h'=[tex]\frac{1}{2}\times 11[/tex]in

Height of drawing, h'=5.5 in

Width of drawing tree=[tex]\frac{1}{2}\times 5[/tex]

Width of drawing tree=[tex]2.5in[/tex]

Hence, Barry's drawing is  5.5 in  tall and 2.5 in wide.

Jack made 9 identical bags using 5 yards of fabric. How much fabric did Jack use for each bag? Solve on paper and check your work on Zearn.

Answers

Answer: 5/9 yards

Step-by-step explanation:

From the question, we are informed that Jack made 9 identical bags using 5 yards of fabric.

To calculate the amount of fabric that Jack use for each bag, we have to divide 5 by 9. Thus will be:

= 5 / 9

Therefore, it means that Jack used 5/9 yards for each bag

A leisure aircraft is owned by the Broadland Flying Group which has 10 members. The costs of keeping the aircraft comprise maintenance costs (including insurance) and the running cost which is mainly fuel. Average fuel consumption is 9 miles per gallon. If the 10 members of the Group are to share costs equally, write down a formula to enable Gordon the treasurer to calculate the annual cost for each member if the aircraft travels n miles in a year, incurs maintenance costs of £M and fuel costs £3 a gallon.

Answers

Answer:

£(M + n/3) / 10

Step-by-step explanation:

Given that :

Number of members = 10

Fuel consumption = 9 miles per gallon

Consumption for n miles = n/9 GALLONS

Cost of fuel = n/ 9 * £3 = 3n / 9 = £n / 3

Maintainace cost = £M

Annual cost per member :

£(M + n/3) / 10
