What Is The Geometric Series1,-5,25,-125.......n=8 Please This Is 30 Points

Answers

Answer 1

Answer:

-5

Step-by-step explanation:

b1 = +1

b2= -5

b3 = +25

b4 = -125

q = -5  (if u times it -5, u will have every second + or -)

q = [tex]\frac{b2}{b1}[/tex] = -5:1 = -5

Answer 2

9514 1404 393

Answer:

  the sum of 8 terms of the series is -65104.

Step-by-step explanation:

The first term is 1.

The common ratio is (-5)/(1) = -5.

The sum of 8 terms is ...

  S8 = a1(r^8 -1)/(r -1)

  S8 = 1((-5)^8 -1)/((-5) -1) = 390624/-6 = -65104

The sum of 8 terms is -65104.

__

The 8th term is 1·(-5)^(8-1) = -78,125.

how to find root hair

Answers

I'll proceed by evaluating total length and surface area by scanned images. For measurements, I suggest to use winrhizo or any similar software. In this case the most important thing to think about is to use the appropiate acquisition parameters, I mean, to set a good resolution during scanning. Pixels of the aquired image should be smaller than root hairs diameter. Therefore, let me try to suggest you a good acquisition resolution. Making a quick research, it seems that hair root diameters range between 0,012 and 0,017 mm, so I suggest a resolution that will give a pixel dimension of 0,002 mm. Root hair diameters should be composed by 6-8 pixels, that is enough for winrhizo measurements. Resolution is measured in dpi, so in "dots/pixel per inch". A inch is 25,4 mm. We need pixels with a diameter of 0,002 mm, so in 25,4 mm we found 12700 pixels. That means 12700 dpi. It's a very high resolution, you need a good scanner and much space in your computer.

Given that the points (12, –4) and (–36, 8) lie on a line, what is the equation of the line?

Answers

The equation of the line passing through the points (12, –4) and (–36, 8) is y = -1/2 x  - 1

The formula for calculating the equation of a line is expressed as:

y = mx + b

m is the slope of the line

b is the y-intercept

Given the coordinate points expressed as (12, –4) and (–36, 8)

Get the slope:

m = 8+4/-36-12

m = 12/-48

m = -1/4

Get the y-intercept "b"

Recall that y = mx + b

8 = -1/4(-36) + b

8 = 9 + b

b = 8 - 9

b = -1

Get the required equation.

Recall that y = mx + b

y = -1/2 x + (-1)

y = -1/2 x - 1

Hence the equation of the line passing through the points (12, –4) and (–36, 8) is y = -1/2 x  - 1

According to a 2014 Pew Research poll, 58% of Americans believe in Hell. Suppose a random sample of 100 Americans is obtained and the number of Americans who believe in Hell is recorded. Can this binomial experiment be approximated using a normal distribution? Be sure to demonstrate your conclusion numerically.

Answers

Testing the conditions, we get that [tex]np = 58 \geq 10[/tex] and [tex]n(1 - p) = 42 \geq 10[/tex], thus, this binomial experiment can be approximated using a normal distribution.

For each person sampled, there are only two possible outcomes. Either they believe in Hell, or they do not. The probability of a person believing in hell is independent of any other person, which means that the binomial distribution is used to solve this question.

Binomial distribution:

Probability of x successes on n trials, with p probability.

If [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex], it can be approximated to the normal distribution.

In this problem:

Sample of size 100, thus [tex]n = 100[/tex].58% believe in Hell, thus [tex]p = 0.58[/tex].

Then

[tex]np = 100(0.58) = 58 \geq 10[/tex]

[tex]n(1 - p) = 100(0.42) = 42 \geq 10[/tex]

[tex]np = 58 \geq 10[/tex] and [tex]n(1 - p) = 42 \geq 10[/tex], thus, this binomial experiment can be approximated using a normal distribution.

Ok so if you were wondering what to do on the box that says this

Move Decimal

Divide

Multiply

Subtract

Bring down

On this, I agree with myself. The solution is straightforward. Simply click them in the sequence listed, beginning with the first and ending with the last. Wow, what sleuthing I did. I realize it's not much, but I was perplexed by this as well, so you could be as well. So here we go with the actual answer. To tackle these sorts of issues, you must employ a technique known as PEMDAS, which stands for.

Parenthisis

Exponent

Multiply

Divide

Add Subtract

I realize I spelt the first one incorrectly, but it's 2 a.m. and I'm doing homework for you. Now we must consider whether or not this has any parenthesis. This particular issue does not. Now we must determine whether or not this issue has exponents, which it does. As mentioned in the response box on the lesson's main page. So we have to consider that (spelled incorrectly, but who cares, it's math class)Now we multiply by a power of ten, so the divisor is a whole number. The following step is to divide by calculating how many times 25 equals 105. I realize it was stolen from the question, but whatever. So there was the explanation; I realize I didn't answer the entire problem, but I didn't have to; it wasn't in the cards.

what is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The high temperature was recorded as 23 7°F = +23.7

the low temperature that same day was recorded as 6.9°F = -6.9 F

so,  difference between the high and low temperatures for that day

= 23.7- (-6.9)

= 30.6

Help, What is the volume of the concrete piece?

Answers

Answer:

72,000

Step-by-step explanation:

multiply everything

Answer: 1,215 in ^ 3

Volume is length x width x height.
I would split the figure into two different parts.

(In the picture I drew a line)

So no let’s find the volume of both shapes.

The fist one is 8 x 5 x 19

You get 19 as the height because the 9 and the 10 need to be added together to get the height of the shape.

8 x 5 = 45

45 x 19 = 855

Now let’s find the volume of shape #2

20 x 8 x 9

20 x 8 = 40

40 x 9 = 360

Now we have the volume of the shape split into two parts so we need to add them together.

855 + 360 = 1,215

I think that’s how you do it. I haven’t done this in a while

Adjoa’s gross salary for last month was Ghc4,687.24. If Ghc421.78 was deducted from Adjoa’s salary pay, how much take-home pay did Adjoa earn this past month?

Answers

Adjoa take-home pay earned for the past month is Ghc4,265.46

From the question,

We are to determine the amount of take-home pay Adjoa earn the past month

From the given information, we have that

Adjoa’s gross salary for last month was Ghc4,687.24

Also

Ghc421.78 was deducted from Adjoa’s salary pay

To determine how much take-home pay Adjoa earn the past month,

We will subtract the amount deducted from Adjoa’s salary pay from Adjoa’s gross salary for last month

That is,

Adjoa take-home pay = Ghc4,687.24 - Ghc421.78

Adjoa take-home pay = Ghc4,265.46
