Answer:
I earned $856 on the first day
Step-by-step explanation:
Let's call
x = earning on the second day
2x = earnings on the first day
3x = earnings on the third day
The total earnings are $2568, thus
x + 2x + 3x = 2568
Simplifying:
6x = 2568
Dividing by 6:
x = 2568/6
x = 428
I earned $428 on the second day.
2x = 2*$428 = $856
I earned $856 on the first day

Read this entry from a blog about service dogs. Lexie, an eight-month-old black Labrador retriever, is sleeping quietly at my feet. I can’t help but think that her soft, velvety ears and alert brown eyes would make her the perfect "doggie model" for pet magazines and pet store ads. However, Lexie will soon have a much more important job to do. In a few months, she will become the loyal companion and service dog for a young man who has been blind since birth. She will help him board public transportation, such as buses, subways, and trains, and she will help him safely cross busy intersections. Lexie will even help the young man avoid obstacles, such as high curbs and low overhangs. Like all dogs in our organization, Lexie has undergone months of specialized training to help a visually impaired person lead an active and independent life. Which statement about this blog is true?

Consider the series
[infinity]
∑ (-1)^n (x+1)^n/ (n+1)!
n=0
a. Find the series' radius and interval of convergence.
b. For what values of x does the series converge absolutely?
c. For what values of x does the series converge coditionally?
(a) If
[tex]f(x)=\displaystyle \sum_{n=0}^\infty (-1)^n \frac{(x+1)^n}{(n+1)!}[/tex]
then by the ratio test, the series converges for all x, since
[tex]\displaystyle \lim_{n\to\infty} \left| \frac{ (-1)^{n+1} \frac{(x+1)^{n+1}}{(n+2)!} }{ (-1)^n \frac{(x+1)^n}{(n+1)!} } \right|=\lim_{n\to\infty}\frac{|x+1|}{n+2}=0[/tex]
so the series radius of convergence is ∞ and the interval of convergence is (-∞, ∞).
(b) The series converges everywhere absolutely, because the ratio test for
[tex]\displaystyle \sum_{n=0}^\infty \frac{|x+1|^n}{(n+1)!}[/tex]
also shows the radius of convergence is ∞.
(c) The series converges absolutely, so conditional convergence is moot.

Answer:
A
Step-by-step explanation:
Translate this sentence into an equation.
28 is the product of Rhonda's age and 2.
Use the variable r to represent Rhonda's age.
The sentence "28 is the product of Rhonda's age and 2" can be translated into the following equation as 28 = 2 × r
In this equation, use the variable 'r' to represent Rhonda's age.
The equation states that the number 28 is equal to the product of 2 and Rhonda's age (r).
This equation describes the relationship between the value 28 and Rhonda's age.
If you know the value of 'r', you can solve for 28, and vice versa.
It's a simple way to express the given information mathematically.
Therefore, the given sentence about product of Rhonda's age and 2 is equal to 28 written in the equation form as 28 = 2 × r .

Answer:
Option (B)
Step-by-step explanation:
Given system of equations is,
x² + y² = 9 ------(1)
[tex]\frac{x^2}{25}-\frac{y^2}{36}=1[/tex] -------(2)
From equation (1),
x² = 9 - y²
Substituting these values in equation (2),

we multiply by the reciprocal when we work with fractions and division.
Now you just multiply across.
Therefore, you have 2/20, which simplifies to 1/10.
A fraction is a part of a whole.
It is expressed as a quotient, in which the numerator is divided by the denominator.
The simplest form of 2/5 divided by 4 is 1/10.
What is a fraction?A fraction is a part of a whole.
It is expressed as a quotient, in which the numerator is divided by the denominator.
Example: 2/3, 5/7, 1/3
We have,
2/5 ÷ 4
= (2/5) / 4
= 2 / (4 x 5 )
We cancel the common factor from the numerator and denominator.
= 2 / (2 x 2 x 5)
= 1 / (2 x 5)
= 1 / 10
We see that there is no common factor to be canceled out from the numerator and the denominator.
= 1/ 10 is our simplest form.
Thus the simplest form of 2/5 divided by 4 is 1/10.
