Answer:

Explanation:

1. First step is to convert mixed fraction to improper fraction

Step 1
Multiply the denominator by the whole number
5 × 9 = 45

Step 2
Add the answer from Step 1 to the numerator
45 + 2 = 47

Step 3
Write answer from Step 2 over the denominator
47/5 - Simplified Solution

Cube root of 47 =1175
And

Cube root of 5 = 125

So answer is 0.3908

In mixed fraction 7 and 59/100

Find the radius of convergence, r, of the series. ∞ xn 2n − 1 n = 1 r = 1 find the interval, i, of convergence of the series. (e

Bingel [31]

Assuming the series is

$\displaystyle\sum_{n\ge1}\frac{x^n}{2n-1}$

The series will converge if

$\displaystyle\lim_{n\to\infty}\left|\frac{\frac{x^{n+1}}{2(n+1)-1}}{\frac{x^n}{2n-1}}\right|$

We have

$\displaystyle\lim_{n\to\infty}\left|\frac{\frac{x^{n+1}}{2(n+1)-1}}{\frac{x^n}{2n-1}}\right|=|x|\lim_{n\to\infty}\frac{\frac1{2n+1}}{\frac1{2n-1}}=|x|-\lim_{n\to\infty}\frac{2n-1}{2n+1}=|x|$

So the series will certainly converge if $-1$ , but we also need to check the endpoints of the interval.

If $x=1$ , then the series is a scaled harmonic series, which we know diverges.

On the other hand, if $x=-1$ , by the alternating series test we can show that the series converges, since

$\left|\dfrac{(-1)^n}{2n-1}\right|=\dfrac1{2n-1}\to0$

and is strictly decreasing.

So, the interval of convergence for the series is $-1\le x$ .

Describe and explain the possible values of s, the number of student tickets sold, and e, the number of tickets sold to nonstude

Marat540 [252]

Answer:

(20,0) , (0,16) , (5,12) , (10,8) , (15,4)

Step-by-step explanation:

Total amount of tickets sold = 80

Per ticket price for students = 4 ; Per ticket price for non students = 5

Let no. of students be s , no. of non students be x

Equation : 4s + 5x = 80

So, Maximum number of student tickets sold (assuming all student, no 'non student' tickets) = 80 / 4 = 20

Maximum number of non student tickets sold (assuming all 'non student', no 'student' tickets) = 80 / 5 = 16

Other possible values {s,x} , as per equation = (5,12) , (10,8) , (15,4)
