Answers
Given, Jada walks at a speed of 3 mph and Elena walks at a speed of 2.8 mph.Both Jada and Elena start walking along a walking trail at the same time.
Let us determine the distance covered by both of them.Distance travelled by Jada in 3 hours is:Distance = Speed × Time= 3 mph × 3 hours= 9 miles Distance travelled by Elena in 3 hours is:Distance = Speed × Time= 2.8 mph × 3 hours= 8.4 miles Thus, Jada will walk 0.6 miles farther than Elena after 3 hours.
To determine how far Jada will walk after 3 hours, we need to calculate the distance traveled based on her speed.
Jada walks at a speed of 3 miles per hour (mph), so we can calculate her distance using the formula:
Distance = Speed × Time
Plugging in the values, we have:
Distance = 3 mph × 3 hours
Distance = 9 miles
Therefore, Jada will walk a distance of 9 miles after 3 hours.

show that the function f(x) = [infinity] x n n! n = 0 is a solution of the differential equation f ′(x) = f(x).
Answers
This equation holds true for any value of x, which means that f(x) = ∑(n=0)(∞) xn/n! is indeed a solution of the differential equation f′(x) = f(x).
To show that the function f(x) = ∑(n=0)(∞) xn/n! is a solution of the differential equation f′(x) = f(x), we need to demonstrate that f′(x) = f(x) holds true for this function.
Let's first compute the derivative of f(x) using the power series representation:
f(x) = ∑(n=0)(∞) xn/n!
f'(x) = ∑(n=1)(∞) nxn-1/n!
Now we can substitute f(x) and f'(x) into the differential equation:
f′(x) = f(x)
∑(n=1)(∞) nxn-1/n! = ∑(n=0)(∞) xn/n!
We can rewrite the left-hand side of this equation by shifting the index of summation by 1:
∑(n=1)(∞) nxn-1/n! = ∑(n=0)(∞) (n+1)xn/n!
We can also factor out an x from each term in the series:
∑(n=0)(∞) (n+1)xn/n! = x∑(n=0)(∞) xn/n!
Now we can see that the right-hand side of this equation is just f(x) multiplied by x, so we can substitute f(x) = ∑(n=0)(∞) xn/n! to get:
x ∑(n=0)(∞) xn/n! = ∑(n=0)(∞) xn/n!

#SPJ11
To show that the function f(x) = ∑(n=0 to infinity) xn/n! is a solution to the differential equation f′(x) = f(x), we need to show that f′(x) = f(x).
First, we find the derivative of f(x):
f′(x) = d/dx [ ∑(n=0 to infinity) xn/n! ]
= ∑(n=1 to infinity) xn-1/n! · d/dx (x)
= ∑(n=1 to infinity) xn-1/n!
Now, we need to show that f′(x) = f(x):
f′(x) = f(x)
∑(n=1 to infinity) xn-1/n! = ∑(n=0 to infinity) xn/n!
To do this, we can write out the first few terms of each series:
f′(x) = ∑(n=1 to infinity) xn-1/n! = x^0/0! + x^1/1! + x^2/2! + x^3/3! + ...
f(x) = ∑(n=0 to infinity) xn/n! = x^0/0! + x^1/1! + x^2/2! + x^3/3! + ...
Notice that the only difference between the two series is the first term. In the f′(x) series, the first term is x^0/0! = 1, while in the f(x) series, the first term is also x^0/0! = 1. Therefore, the two series are identical, and we have shown that f′(x) = f(x).
Therefore, f(x) = ∑(n=0 to infinity) xn/n! is indeed a solution to the differential equation f′(x) = f(x).

The average score of students in the first group is 39, the second group is 32, and the third group is 43. If the numbers of students in the three groups are 24, 26, and 27, respectively, find the average score of all students.
Answers
The average score of all students, calculated by taking a weighted average based on the number of students in each group, is 38. The overall performance is slightly below the group averages.
The average score of students in the first, second, and third groups are 39, 32, and 43, respectively. There are 24 students in the first group, 26 students in the second group, and 27 students in the third group.
To find the average score of all students, we need to take a weighted average of the scores in each group, with the number of students in each group as the weights.
Here's how to do it: First, we calculate the total number of students:24 + 26 + 27 = 77. Then, we calculate the total score across all students: 39*24 + 32*26 + 43*27 = 936 + 832 + 1161 = 2929
Finally, we divide the total score by the total number of students to get the average score:2929/77 = 38. The average score of all students is 38.
This means that the overall performance of all the students is slightly below the average of the scores in each group.

When can parallelism make your algorithms run faster when could it make your algorithms run slower?
Answers
When an algorithm necessitates extensive sharing of instantaneous results, parallelism slows it down. Because there are multiple independent parallel processes and the right number of threads, parallelism will speed up an algorithm.
What algorithm is parallelizable?The ones with data dependencies are the most challenging. It will be exceedingly challenging, for instance, if you are dealing with a vector and the input for the computation at point n depends on the output at position n-1.
When this occurs, you must comprehend what the original algorithm is doing and take an alternative approach. For the aforementioned case, it might be a difficulty with digital signal processing including a feedback-containing digital filter. These are challenging to parallelize, but that is not the sole solution. Instead, you might use the filter and signal's fast Fourier transforms, multiply them, and then perform the inverse transform.

Calculate the change in thermal when 230 g of water warms from 12c to 90c
Answers
The change in thermal energy is 75.06 kJ.
To calculate the change in thermal energy, we need to use the specific heat capacity of water, which is 4.184 J/(g°C).
First, we need to calculate the change in temperature:
ΔT = 90°C - 12°C
ΔT = 78°C
Next, we can calculate the change in thermal energy:
ΔQ = m × c × ΔT
where m is the mass of water and c is the specific heat capacity of water.
ΔQ = 230 g × 4.184 J/(g°C) × 78°C
ΔQ = 75060.96 J or 75.06 kJ (rounded to two decimal places).

Allison made 87 shots and scored 191 total points. This implies two things:
t + h = 87 ________(1)
2t + 3h = 191 ______(2)

What is a set?A set is a collection of items where there are operations such as:

(b)
The set S = {x | x² + 4x − 5 = 0}.
Solve for x.
x² + 4x - 5 = 0
x² + (5 - 1)x - 5 = 0
x² + 5x - x - 5 = 0
x(x + 5) - 1(x + 5) = 0
(x + 5) (x - 1) = 0
x = -5x + 5 = 0
x - 1 = 0
x = 1
