The first five terms of the power series are 1 - 16x + 256x^2 - 4096x^3 + 65536x^4. The interval of convergence for this power series is (-1/16, 1/16) with a center of convergence at x = 0.
To find the power series representation of f(x) = 1/(1 + 16x), we can use the formula for the sum of an infinite geometric series. The formula is given as 1/(1 - r), where r is the common ratio. In this case, the common ratio is -16x. Expanding the function as a geometric series, we get 1 - 16x + 256x^2 - 4096x^3 + 65536x^4, which represents the first five terms of the power series.
To determine the interval of convergence, we need to find the values of x for which the series converges. For a geometric series, the series converges if the absolute value of the common ratio is less than 1. In this case, we have -1 < -16x < 1. Solving this inequality, we get -1/16 < x < 1/16. Therefore, the interval of convergence is (-1/16, 1/16).
The center of convergence for a power series is the value of x around which the series is centered. In this case, the series is centered at x = 0, as it is a Maclaurin series.

Danny and his cousin Olivia are picking apples in their grandparents' orchard. Danny has filled 11 baskets with apples and is filling them at a rate of 5 baskets per hour. Olivia has 12 full baskets and will continue picking at 4 baskets per hour. Once the cousins get to the point where they have filled the same number of baskets, they will carry them to the barn and then eat lunch. How much fruit will they have picked by then? How long will that take?
Olivia and Danny have each filled ? baskets in ? hour(s)
Answer:
Answer: Olivia and Danny have each filled 16 baskets in 1 hour
Step-by-step explanation:
We can solve this using simultaneous equations.
Let h be the number of hours of picking apples when both have the same number of baskets
Danny already has 11 baskets. If he picks apples for 1 hour and fills them at the rate of 5 baskets per hour he will have filled a total of
11 + 5h baskets after h hours
Olivia has 12 baskets filled and is filling baskets at 4 baskets per hour
After h hours the number of filled baskets she has
= 12 + 4h
Equate the two
11 + 5h = 12 + 4h
Subtract 11 from both sides
11 - 11 + 5h = 12 - 11 + 4h
5h = 1 + 4h
Subtract 4h from both sides:
5h - 4h = 1
h = 1
Number of baskets filled after 1 hour (including the original baskets filled) = 11 + 5(1) = 16 = 12 + 4(1)
Answer: Olivia and Danny have each filled 16 baskets in 1 hour

a group of students carried out a density experiment for an nacl solution and found the following: mean (xm) = 1.060 g/ml, standard deviation (sx) = 0.00773 g/ml, number of measurements = 6.
the literature value for the density based on the known concentration of nacl is 1.071 g/ml.
is there a significant difference for these two values at the 95% confidence level?
No, there is not a significant difference between these two values at the 95% confidence level.
The difference between the mean and literature values is 0.011 g/ml, which is less than the standard error of the mean (0.00387 g/ml). Therefore, the difference is not statistically significant. To reach a 95% confidence level, the difference must be greater than two standard errors of the mean. This would mean that the difference must be greater than 0.00773 g/ml, which it is not. Therefore, there is no significant difference between these two values at the 95% confidence level.

A printer is printing photos. For every 6 photos, the printer takes 2 minutes.
Complete the table below showing the number of photos and the time it takes to print them.
Answer:
Next to 6 is 9, next to 15 is 27, and next to 3 is 5
Step-by-step explanation:
If you imagine 6 photos for every 2 minutes as a fraction and simplify it, the answer to this would be 3 photos for every 1 minute (basically 3/1). By using this unit fraction, you'll see that you're supposed multiply the amount of minutes by 3, or you can divide the # of photos by 3.
For 3 mins, you multiply that by 3 to get 9 photos.
For 9 mins, you multiply that by 3 to get 27 photos
For 15 photos, you divide that by 3 to get 5 photos.

How do you convert microl to l?
Microliters (µL) and liters (L) are both units of volume measurement. A microliter is a very small unit of volume, equivalent to one millionth of a liter. To convert microliters to liters, we can use a simple conversion factor.
The conversion factor is based on the fact that one liter is equivalent to one million microliters. Therefore, to convert microliters to liters, we divide the number of microliters by one million. This can be expressed as:
L = µL / 1,000,000
For example, if we have a volume of 500 µL that we want to convert to liters, we can use the formula above as follows:
L = 500 µL / 1,000,000
L = 0.0005 L
Therefore, 500 µL is equivalent to 0.0005 liters.
It is important to keep track of the units when making conversions and to use appropriate significant figures. Additionally, it is worth noting that microliters are often used in situations where very small volumes are involved, such as in medical or laboratory settings, whereas liters are used for larger volumes such as in the context of cooking or liquid measurements.

A partly-full paint can has 0.878 U.S. gallons of paint left in it. (a) What is the volume of the paint, in cubic meters? (b) If all the remaining paint is used to coat a wall evenly (wall area = 13.7 m2), how thick is the layer of wet paint? Give your answer in meters.
a) The volume of paint left in the can is:
.878 gallons * 0.00378541 m^3/gallon = 0.003321 m^3
b) the thickness of the layer of wet paint is 0.000242 meters or 0.242 millimeters (since there are 1000 millimeters in a meter).
(a) To convert gallons to cubic meters, we need to know the conversion factor between the two units. One U.S. gallon is equal to 0.00378541 cubic meters. Therefore, the volume of paint left in the can is:
0.878 gallons * 0.00378541 m^3/gallon = 0.003321 m^3
(b) We can use the formula for the volume of a rectangular solid to find the volume of wet paint needed to coat the wall evenly:
Volume = area * thickness
We want to solve for the thickness, so we rearrange the formula to get:
Thickness = Volume / area
The volume of wet paint needed is equal to the volume of dry paint needed since they both occupy the same space when the paint dries. Therefore, the volume of wet paint needed is:
0.003321 m^3
The area of the wall is given as:
13.7 m^2
So the thickness of the layer of wet paint is:
0.003321 m^3 / 13.7 m^2 = 0.000242 m
Therefore, the thickness of the layer of wet paint is 0.000242 meters or 0.242 millimeters (since there are 1000 millimeters in a meter).

Answer:
(- 3, 2 )
Step-by-step explanation:
Given the 2 equations
x + 3y = 3 → (1)
- 2x + 3y = 12 → (2)
Subtract (1 ) from (2) term by term to eliminate y
- 2x - x + (3y - 3y) = 12 - 3
- 3x = 9 ( divide both sides by - 3 )
x = - 3
Substitute x = - 3 into either of the 2 equations and solve for y
Substituting into (1)
- 3 + 3y = 3 ( add 3 to both sides )
3y = 6 ( divide both sides by 3 )
y = 2
solution is (- 3, 2 )

An advertising agency increased their fees to an $80 setup fee plus $4 for every advertisement. Write a rule forthe new fee. Write ordered pairs for the fees for 10, 20, 30, and 40 advertisements.
Given that the advertising company had a setup fee of $80, this would mean that
\(y=80\)Next, since it is stated that they add $4 for every advertisment, we let x as the number of advertisement, and this would mean that we add 4x to the equation that we initially had
\(y=80+4x\)Now, to write ordered pairs for the fees for 10, 20, 30, and 40 advertisements, we just have to substitute these values to the equation
x = 10

im cant figure out how to do this one ((-3)^2)^-3
Answer:
\(\dfrac{1}{729}\)
Step-by-step explanation:
\(\left(\dfrac{}{}(-3)^2\dfrac{}{}\right)^{-3}\)
First, we should evaluate inside the large parentheses:
\((-3)^2 = (-3)\cdot (-3) = 9\)
We know that a number to a positive exponent is equal to the base number multiplied by itself as many times as the exponent. For example,
\(4^3 = 4 \, \cdot\, 4\, \cdot \,4\)
↑1 ↑2 ↑3 times because the exponent is 3
Next, we can put the value 9 into where \((-3)^2\) was originally:
\((9)^{-3}\)
We know that a number to a negative power is equal to 1 divided by that number to the absolute value of that negative power. For example,
\(3^{-2} = \dfrac{1}{3^2} = \dfrac{1}{3\cdot 3} = \dfrac{1}{9}\)
Finally, we can apply this principle to the \(9^{-3}\):
\(9^{-3} = \dfrac{1}{9^3} = \boxed{\dfrac{1}{729}}\)

Answer: ( . = multiplication sign)
1. 24
2. 4 questions
3. 3 questions
Step-by-step explanation:
1. You first need to find how many points each part was worth. To do this, you need to find the lowest common multiple for 6 and 8. The lowest common multiple is 24.
2. Part A has questions that were each worth 6 points so, you need to find the value of X in this equation: X . 6 = 24 .
The value of X is 4.
3. Part B had questions that were 8 points each so you need to find the value of X in this equation: X . 8 = 24 .

Ali and billy ran around a race track. How many more metres did Ali ran than billy in one lap? (Find perimeter)
Answer:
Ali ran 25.13 m more than bily
Step-by-step explanation:
From the diagram, we can see that bully runs with the inner track line while Ali runs with the outer track line.
Thus;
Diameter of inner semi circle = 20 m
Diameter of outer semi circle = 20 + 4 + 4 = 28 m
Perimeter of inner semi circle = πD/2 = 10π
Perimeter of outer semi circle = πD/2 = 14π
Now, perimeter of Billy = 80 + 80 + 10π + 10π = 222.83 m
Perimeter of Ali = 80 + 80 + 14π + 14π = 247.96 m
Thus, in one lap, difference in distance between Ali and billy = 247.96 - 222.83 = 25.13 m
The coach recorded the time it took 14 students to run a mile. The times are as follows: 9:23, 8:15, 9:23, 9:01, 6:55, 7:20, 9:14, 6:21, 7:12, 7:34, 6:10, 9:15, 9:18. Use the data set to complete the frequency table. Then use the table to make a histogram
The histogram for the frequency table is illustrated below.
To create the frequency table, we need to count how many times each time appears in the data set. The time 9:23 appears twice, so we would put a frequency of 2 in the row corresponding to 9:23. We do this for each time in the data set.
Here is the completed frequency table:
Time Frequency
6:10 1
6:21 1
6:55 1
7:12 1
7:20 1
7:34 1
8:15 1
9:01 1
9:14 1
9:15 1
9:18 1
9:23 2
As you can see, each time appears only once or twice in the data set. This tells us that there is no dominant time that most students ran the mile in.
To create the histogram, we'll draw a bar above each time on the x-axis with a height equal to the frequency of that time. For example, there are two times of 9:23, so we'll draw a bar above 9:23 with a height of 2.
As you can see, the histogram shows a relatively even distribution of times. The most common times are around 9 minutes, but there are also several times below 8 minutes and one time below 7 minutes.
