find the taylor series up to the degree 4 term at a = 8 for f(x) = ex.
The Taylor series up to the degree 4 terms is:
e^8 + (x - 8)e^8 + (x - 8)^2/2! e^8 + (x - 8)^3/3! e^8 + (x - 8)^4/4! e^8
The Taylor series of a function f(x) at point a is an infinite sum of terms that approximates the value of the function near point a. The general form of the Taylor series of f(x) at a is:
f(x) = f(a) + (x - a)f'(a) + (x - a)^2/2! f''(a) + (x - a)^3/3! f'''(a) + ...
Where,
f'(a) is the first derivative of f(x) at a.f''(a) is the second derivative of f(x) at a.f'''(a) is the third derivative of f(x) at a.In the case of e^x, the function is infinitely differentiable, so all its derivatives are equal to itself. Hence the Taylor series at a=8 is:
e^8 + (x-8)e^8 + (x-8)^2/2! e^8 + (x-8)^3/3! e^8 + (x-8)^4/4! e^8 + ....
by taking the degree 4 terms we can find the Taylor series of e^x at a = 8 up to the degree 4 terms, which is
e^8 + (x-8)e^8 + (x-8)^2/2! e^8 + (x-8)^3/3! e^8 + (x-8)^4/4! e^8

Two friends, Jeanette and Zoe, are growing out their hair. They plan to cut it off at a certain point and donate it to a charity that makes wigs for people with cancer. Jeanette's hair is already 29 centimeters long and grows at a constant rate of 1 centimeter per month. Zoe's hair is 12 centimeters and growing at a speed of 2 centimeters per month. If the girls get their hair cut on a certain day, they will have exactly the same length to donate. How long will their hair be? How long will that take?
Part A:
Using the variables y for total growth and x for rate of change answer the questions below.
Create the equation for Jeanette's hair growth:
Create the equation for Zoe's hair growth
Answer:
Step-by-step explanation:
J: y = 29 cm + (1 cm/mo)x
Z: y = 12 cm + (2 cm/mo)x
29 cm + (1 cm/mo)x = 12 cm + (2 cm/mo)x
Solve for x to find how many months it will take for them to have the same length of hair:
29 cm - 12 cm = (2 cm/mo)x - (1 cm/mo)x
17 cm = (1 cm/mo)x
x = (17 cm) / (1 cm/mo) = 17 months
Plug this value for x (17 months) into the equations to find how long their hair will be:
J: y = 29 cm + (1 cm/mo)(17 mo) = 46 cm
Z: y = 12 cm + (2 cm/mo)(17 mo) = 46 cm
This shows that it will take 17 months for each girl's hair to be 46 cm long.
Xochitl went into a movie theater and bought 6 bags of popcorn and 4 drinks, costing a total of $65. Alonso went into the same movie theater and bought 9 bags of popcorn and 8 drinks, costing a total of $107.50. Determine the price of each bag of popcorn and the price of each drink.
The cost of bag of popcorn is $7.5 and that of one drink is $5.
How to find the general equation of a Straight line?The formula for finding the general equation of a straight line is -
[y] = [m[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have Xochitl who went into a movie theatre and bought 6 bags of popcorn and 4 drinks, costing a total of $65, Alonso went into the same movie theatre and bought 9 bags of popcorn and 8 drinks, costing a total of $107.50.
Assume that the cost of one popcorn bag is $[x] and one drink is $[y].
Then we can write -
6x + 4y = 65
6x + 4y = 659x + 8y = 107.5
Plot the graph of both equations and the points of intersection would be the solution set. Refer to the graph below. We get x = $7.5 and y = $5.
Therefore, the cost of bag of popcorn is $7.5 and that of one drink is $5.

Using the maxima and minima of the function, produce upper and lower estimates of the integral
I=∫∫De^5(x2+y2)dA where D is the circular disk: x^2+y^2≤4
In calculus, we can find the maximum and minimum value of any function or variable without on looking at the graph of the function.
Maxima will be the giant point on the curve within the given range and minima would be the minimum point on the curve. The combination of both is extrema.
Since 0 ≤ x^2 + y^2 ≤ 6, we have e^ (6*0) ≤ e^ (6(x^2 + y^2)) ≤ e^ (6*6) on D.
So, ∫∫ 1 dA ≤ ∫∫ e^ (6(x^2 + y^2)) dA ≤ ∫∫ e^36 dA
==> 6π ≤ ∫∫ e^ (6(x^2 + y^2)) dA ≤ 6π * e^36, since the area of D is 6π.

Adrian grabbed a bag of mandarin oranges off the shelf and spilled them all out on the counter. He divided them into 4 piles, but there was 3 left over. He rearranged them into 5 piles but this time there were 2 left over. Then he tried putting them into six piles, but there were 3 left over. When he tried 7 piles there were 3 left over again. Finally he put them into 3 piles and he didn’t have any left over. If the number of mandarins in the bag was less than 100, how many mandarins were in the bag?
The number of mandarins in the bag is 3 * 33 + 3 = 102 mandarins.
How did we determine the values?This is a Diophantine equation problem, which is a type of mathematical problem that looks for integers that satisfy a given equation.
We know that the number of mandarins in the bag is equal to 4n + 3, 5m + 2 and 6p + 3 and 7q + 3 for some integers n, m, p and q.
We also know that the number of mandarins in the bag is equal to 3r, where r is an integer.
From the information provided, we can set up the following equation:
4n + 3 = 5m + 2 = 6p + 3 = 7q + 3 = 3r
Now we can use the information that when he finally put them into 3 piles and he didn't have any left over, meaning that the number of mandarins in the bag is divisible by 3, we can see that the remaining number in each case is 3.
Thus the number of mandarins in the bag is 3 * (some integer) + 3.
We can then use the information that the number of mandarins in the bag was less than 100, meaning the possible value of r is less than 34.
Testing values of r starting from 1, we can see that r = 33 satisfies the equation and the number of mandarins in the bag is 3 * 33 + 3 = 102 mandarins

Penny reads 14 pages in 1/4 hour. What is the unit rate for hours per page
Answer:
56 pages per hour
Step-by-step explanation:
Penny reads 14 pages in 1/4 of an hour.
An hour is 4 times more than 1/4 of an hour (you could think of it as 15 minutes compared to 60 minutes)
Multiply the amount penny reads in 1/4 of an hour (14 pages) by 4 to get the rate she reads in 1 hour.
14 x 4 = 56
Now add the rate of time (per hour) to get that she reads a total of 56 pages per hour.

2) A robot vacuum cleans a dirty floor using multiple passes. During each pass, 17% of the dirt is removed. If the floor initially has 460.0 ml of dirt, how much dirt will remain after 9 passes?
86 ml of dirt will remain after 9 passes
What is an equation?An equation is an expression showing the relationship between numbers and variables.
Let y represent the amount of dirt on the floor after x passes, hence:
y = abˣ
During each pass, 17% of the dirt is removed, therefore b = 100% - 17% = 0.83
If the floor initially has 460.0 ml of dirt, then a = 460.
The equation becomes:
y = 460(0.83)ˣ

of the translated point Q'?
O (10,0)
By applying the required transformation, the coordinates of the translated point Q' are (-1, -11).
What is translation?A translation is a type of transformation in geometry that moves every point of a figure in a fixed direction and by a fixed distance, without changing its size or shape. It is one of the basic geometric transformations along with rotation, reflection, and dilation.
What are coordinates?Coordinates are a set of values that determine the position of a point in a certain space. In a two-dimensional space, coordinates are usually represented by an ordered pair of numbers (x, y), where x is the horizontal distance from a fixed point called the origin and y is the vertical distance from the origin. In a three-dimensional space, coordinates are represented by an ordered triple of numbers (x, y, z). Coordinates are often used to locate points in space, to describe the position of objects, and to plot graphs.
To find the coordinates of the translated point Q', we can use the rule that in a translation, the x-coordinate is decreased by the horizontal translation distance and the y-coordinate is decreased by the vertical translation distance.
Given that point Q has coordinates (5, -6) and is translated 6 units left and 5 units down, we can find the coordinates of the translated point Q' as follows:
x' = x - 6 (horizontal translation distance)
y' = y - 5 (vertical translation distance)
So the coordinates of the translated point Q' are:
x' = 5 - 6 = -1
y' = -6 - 5 = -11

The set W1 could be a basis for R3 if it spans R3 and is linearly independent, but without the specific elements of W1, it's not possible to determine if it meets those criteria.
The specific elements that make up the set W1. However, I can tell you that to be a basis for R3, a set of vectors must meet two criteria:
The set must span R3, meaning that any vector in R3 can be written as a linear combination of the vectors in the set.The set must be linearly independent, meaning that no vector in the set can be written as a linear combination of the other vectors in the set.So, depending on the specific elements of W1, it could be either A, B, or C.
If the set W1 doesn't span R3, it would be A.
If the set W1 is linearly dependent, it would be C.
If both conditions are met the set is a basis, so the answer would be B.
