Step-by-step explanation:
uppose that you are told that the Taylor series of f(x)=x3ex2
about x=0
is
x3+x5+x72!+x93!+x114!+⋯.
Find each of the following:
ddx(x3ex2)∣∣∣x=0=
d7dx7(x3ex2)∣∣∣x=
a. Using Taylor series d(x³eˣ²)/dx about x = 0 is x⁴.
b. Using Taylor series d⁷(x³eˣ²)/dx⁷ about x = 0 is x¹⁰.
What is a Taylor series expansion?A Taylor series is a polynomial expansion of a function about a given point. It is given by f(x - a) = ∑(x - a)ⁿfⁿ(x - a)/n! where
a = point where f(x) is evaluated fⁿ(a) = nth derivative of f(x) about a and n is a positive integerGiven that the Taylor series of the function f(x) = x³eˣ² about x = 0 is
f(x) = x³ + x⁵ + x⁷/2! + x⁹/3! + x¹¹/4!, (1) we proceed to find the given variables
a. To find d( x³eˣ²)/dx about x = 0, the Taylor series expansion about x = 0 is given by
f(x - a) = ∑(x - a)ⁿfⁿ(a)/n!
f(x - 0) = ∑(x - 0)ⁿf(0)/n!
f(x) = ∑xⁿf(0)/n!
f(x) = x⁰f(x)/0! + xf(x)/1! + x²f(x)/2! + x³f(x)/3! + ....
f(x) = f(x) + xf¹(x) + x²f²(x)/2! + x³f³(x)/3! + ....(2)
Since fⁿ(x) is the nth derivative of f(x), and we desire f¹(x) which is the first derivative of f(x). Comparing equations (1) and (2), we have that
x⁵ = xf¹(x)
f¹(x) = x⁵/x
= x⁴
So, d( x³eˣ²)/dx about x = 0 is x⁴.
b. To find d⁷( x³eˣ²)/dx⁷ about x = 0, the Taylor series expansion about x = 0 is given by
f(x - a) = ∑(x - a)ⁿfⁿ(a)/n!
f(x - 0) = ∑(x - 0)ⁿf(0)/n!
f(x) = ∑xⁿf(0)/n!
f(x) = x⁰f(x)/0! + xf(x)/1! + x²f(x)/2! + x³f(x)/3! + ....
Expanding it up to the 8 th term, we have that
f(x) = f(x) + xf¹(x) + x²f²(x)/2! + x³f³(x)/3! + x⁴f⁴(x)/4! + x⁵f⁵(x)/5! + x⁶f⁶(x)/6! + x⁷f⁷(x)/7!.....(3)
Now expanding equation (1) above to the 8th term by following the pattern, we have that
f(x) = x³ + x⁵ + x⁷/2! + x⁹/3! + x¹¹/4! + x¹³/5! + x¹⁵/6! + x¹⁷/7!.....(4)
Since fⁿ(x) is the nth derivative of f(x), and we desire f⁷(x) which is the seventh derivative of f(x). Comparing equations (3) and (4), we have that
x⁷f⁷(x)/7! = x¹⁷/7!
f⁷(x) = x¹⁷/x⁷
= x¹⁰
So, d⁷( x³eˣ²)/dx⁷ about x = 0 is x¹⁰.

Answer: C: 5/8
Step-by-step explanation:
Simply 5/8 of the bar is filled in
Using probability, we can find probability of the random variable, x falling in the shaded region as to be 5/8.
Here, we have,
Probability is the ratio of favorable outcomes to all other potential outcomes of an event. The symbol x can be used to express the quantity of successful outcomes for an experiment with 'n' outcomes. The following formula can be used to determine an event's probability.
Positive Outcomes/Total Results = x/n = Probability(Event)
Let's look at a simple example to better understand probability. Imagine that we need to predict whether it will rain or not. The right response to this question is "Yes" or "No." Whether it rains or not is uncertain. Probability is used to predict the outcomes when tossing coins, rolling dice, or drawing cards from a deck of cards.
Here in the question,
Total region = 8.
Shaded region = 5
So, probability of falling in the shaded region = 5/8

A phone store sells Android phones for $400 and iOS phones for $650 each. This
week they sold a total of 110 phones and earned $54,000. How many Android and
how many iOS phones did they sell?
Let's assume that the number of Android phones sold is x and the number of iOS phones sold is y. Then we can write two equations based on the given information:
x + y = 110 (equation 1)
400x + 650y = 54000 (equation 2)
To solve for x and y, we can use any method of solving systems of equations. Here, we will use the substitution method:
From equation 1, we can solve for x in terms of y: x = 110 - y
Substitute x = 110 - y into equation 2 and solve for y:
400(110 - y) + 650y = 54000
44000 - 400y + 650y = 54000
250y = 10000
y = 40
Substitute y = 40 into equation 1 and solve for x:
x + 40 = 110
x = 70
Therefore, the phone store sold 70 Android phones and 40 iOS phones.

Using the properties of a parallelogram, the values of x and y are:
x = 9; y = 22.
How to Find x and y in the Parallelogram?Since the opposite sides are parallel and equal to each other in the parallelogram above, therefore, Opposite angles are equal (or congruent) while the consecutive angles are supplementary to each other.
Therefore, we have:
6y = 180 - 48
6y = 132
Divide both sides by 6:
6y/6 = 132/6
y = 22
(5x + 3) + 6y = 180
5x + 3 + 6(22) = 180

2 miles from school. On her way home,
she runs of the way and walks the rest.
How far does she walk? Explain.
Gabriela walks 1 mile distance on her way home from school as she is running part of the way.
What is distance?The distance between two things is measured in distance units like miles, kilometres, or metres. Given that it only possesses magnitude and not direction, distance is a scalar number.
We must ascertain Gabriela's total trip distance before we can respond to this query.
We can get the overall distance by adding the distance she runs to the distance she walks because she runs a portion of the route and walks the other.
Gabriela commutes two miles to school, so
She needs to travel a total of 2 miles.
We need to figure out how far she runs because she is running a portion of the way.
Since running is typically faster than walking, we can infer that she covers the distance in one mile by running half of it.
She will therefore need to walk the additional mile.
Gabriela walks a mile on her way home from school, which is the answer to the question.
This is because she walks the remaining mile and runs the first mile.

Step-by-step explanation:
To find the total amount in the account after 6 years, we can use the compound interest formula.
Compound Interest Formula[tex]\boxed{\sf A=P\left(1+\dfrac{r}{n}\right)^{nt}}[/tex]
where:
A = Final amount.P = Principal amount.r = Interest rate (in decimal form).n = Number of times interest is applied per year.t = Time (in years).Given values:
P = $2,000r = 4.6% = 0.046n = 4 (quarterly)t = 6 yearsSubstitute the given values into the formula and solve for A:
[tex]\implies \sf A=2000\left(1+\dfrac{0.046}{4}\right)^{4 \cdot 6}[/tex]

Claude has a 10-pound package of hamburger meat and an
11.5-pound package of hamburger meat. Can he make the number of
hamburger patties shown? Choose Yes or No.
A. 87 1/4-pound hamburger patties
B. 45 1/2-pound hamburger patties
C. 30 1/2 -pound and 274-pound hamburger patties
D. 29 3/4 -pound hamburger patties
Answer: We can solve this problem by finding the total weight of the meat and then dividing by the weight of each patty to see if we can make the desired number of patties.
Let's add the weights of the two packages of meat:
10 + 11.5 = 21.5
For option A, we need 87 1/4-pound patties.
Each pound of meat will yield 4 patties of this size, so 21.5 pounds of meat will yield:
21.5 x 4 = 86 patties
Since we need 87 patties, Claude does not have enough meat for option A.
For option B, we need 45 1/2-pound patties.
Each pound of meat will yield 2 patties of this size, so 21.5 pounds of meat will yield:
21.5 x 2 = 43 patties
Since we need 45 patties, Claude does not have enough meat for option B.
For option C, we need 30 1/2-pound patties and 2 74-pound patties.
Each pound of meat will yield 2 patties of the smaller size and 1 patty of the larger size, so 21.5 pounds of meat will yield:
(21.5 x 2) + (2 x 1) = 43 + 2 = 45 patties
Since Claude only has 21.5 pounds of meat, he does not have enough for option C.
For option D, we need 29 3/4-pound patties.
Each pound of meat will yield 1.5 patties of this size, so 21.5 pounds of meat will yield:
21.5 x 1.5 = 32.25 patties
Since we only need 29.75 patties, Claude has enough meat for option D.
Therefore, the answer is Yes, Claude can make 29 3/4-pound hamburger patties.

Answer:
See explanation.
Step-by-step explanation:
Let's analyze each solution to determine if it's viable or non-viable based on the given constraints: Johnnie and Amy have $38.50, and they cannot buy more than 7 lunches.
1. 8 slices of pizza and 0 hamburgers
This solution is non-viable because they are not allowed to buy more than 7 lunches. In this case, they would be buying 8 lunches.
2. 5 slices of pizza and 2 hamburgers
Cost: 5×4.75+2×5.55=23.75+11.10=34.85
This solution is viable because the total cost is within their budget, and they are buying 7 lunches.
3. 4 slices of pizza and 3 hamburgers
Cost: 4×4.75+3×5.55=19.00+16.65=35.65
This solution is viable because the total cost is within their budget, and they are buying 7 lunches.
4. 3 slices of pizza and 2 hamburgers
Cost: 3×4.75+2×5.55=14.25+11.10=25.35
This solution is non-viable because they are only buying 5 lunches, which is less than the maximum allowed. But if it is acceptable to only buy below 7 lunches, then this solution can be viable.
5. 2 slices of pizza and 6 hamburgers
Cost: 2×4.75+6×5.55=9.50+33.30=42.80
This solution is non-viable because the total cost exceeds their budget.
6. 0 slices of pizza and 7 hamburgers
Cost: 7×5.55=38.85
This solution is non-viable because the total cost exceeds their budget.
In conclusion, the viable solutions are:
5 slices of pizza and 2 hamburgers
4 slices of pizza and 3 hamburgers
Possible in being viable:
3 slices of pizza and 2 hamburgers
how do you do comparison for percents
In order to do a comparison for percents, you must convert them to decimal form and then juxtapose the decimal values side by side to see which is greater or less.
What are percents?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. The percent sign is commonly used, however the acronyms pct., pct, and sometimes pc are also used. A % is a number with no dimensions; it has no unit of measurement.
To calculate the percentage, divide the amount by the total value and multiply the result by 100.
Divide a percentage by 100 to get a decimal. So 25% is equal to 25/100, or 0.25. Multiply a decimal by 100 (simply shift the decimal point two places to the right) to convert it to a percentage. For example, 0.065 equals 6.5% and 3.75 equals 375%.
