a. Rewrite the series in sigma notation
b. Write an explicit formula for the nth partial sum
a) The infinite series in sigma notation is described by this expression:
[tex]y = \sum \limits_{i=1}^{\infty} \frac{1}{i\cdot (i+2)}[/tex] (1)
b) The explicit formula for the n-th partial sum is represented by the following expression:
[tex]y = \frac{1}{i\cdot (i+2)}[/tex], i ∈ [tex]\mathbb{N}[/tex] (2)
How to derive an expression for a monotonous series
An infinite series is monotonous when it is bounded, that is, when the limit of the infinite series exists. In this case, we have an evidence of monotony in the denominators of the terms of the given series. In two consecutive terms, the latter always have a denominator greater than the former.
a) The series in sigma notation is now described below:
[tex]y = \sum \limits_{i=1}^{\infty} \frac{1}{i\cdot (i+2)}[/tex]
b) The explicit formula for the n-th partial sum is defined by the expression within the sum, which is now presented below:
[tex]y = \frac{1}{i\cdot (i+2)}[/tex], i ∈ [tex]\mathbb{N}[/tex]

If the first number is increased by 7 and the second number is reduced by 6 times, the sum of these numbers is 29.
If the first number is reduced by 5 and the second number is increased 2 times, the difference between the second and first number is 9.
Find these numbers.
Answer:
First number = 20
Second number = 12
Explanation:
Let the 1st number be x
Let the 2nd number be y
=====================
Condition 1
[tex]\sf \rightarrow x + 7 + \dfrac{y}{6} = 29[/tex]
[tex]\rightarrow \sf x=-\dfrac{y}{6}+22[/tex]
=====================
Condition 2
[tex]\rightarrow \sf 2y - (x - 5) = 9[/tex]
[tex]\rightarrow \sf x = 2y -4[/tex]
=====================
Substitute equations
[tex]\rightarrow \sf -\dfrac{y}{6}+22 = 2y-4[/tex]
[tex]\rightarrow \sf y=12[/tex]
=====================
Find value of 1st number
[tex]\rightarrow \sf x = 2y - 4[/tex]
[tex]\sf \rightarrow x = 2(12) - 4[/tex]
[tex]\rightarrow \sf x = 20[/tex]
What are the period, phase shift, and vertical shift of y = csc[3(x 4)] 6?
The period of the given function is 2π/3, the phase shift is 4, and the vertical shift is 6 units.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a trigonometric function:
y = csc[3(x+ 4)]+ 6
Every each revolution of 2π the function repeats the same value for every x.
The period of the original function is 2π
For the given function plug 2π
y = csc[3(x+ 4)+2π]+ 6
y = csc[3(x+ 2π/3+4)]+ 6
The period of the function will be 2π/3
From the function, the phase shift = 4
And vertical shift = 6
Thus, the period of the given function is 2π/3, the phase shift is 4, and the vertical shift is 6 units.

Sales $100 10 12 16 18 22 24 Temperature °C (a) How would you characterize the relationship between the money spent on calling fans to the temperature? Explain. (b) The function y=20x+0 is used to model this situation. What is the predicted amount of sales if the temperature is 21 degrees Celsius? Show your work. (c) What does the number 0 in the function mean in the context of this situation? Answers:
#1
As this is a scatter plot so we have to draw a suitable line then have to find the equation of line inorder to fulfill our requirements.
#2
y=20x+0Put temperature as 21(x)
y=20(21)y=420#3
0 is the y intercept or the initial amount of sales
It's denoting to the fact that there were initially 0 boxes
Please help me ASAP!!!!!
Step-by-step explanation:
when you are on that level of math that you get this type of question - this is totally easy.
we get the extreme point(s) of a function by finding the zeros of the first derivative of the function.
f'(x) = 4x - 8
so,
0 = 4x - 8
8 = 4x
x = 2
to determine whether it is a minimum or a maximum, we have 2 choices :
the quick way for a quadratic (parabola) equation by looking at the factor of x² : is it >0, then the parabola opens up upwards, and the extreme point is therefore a minimum. if it is <0, then it opens downward, and the extreme point is a maximum.
in our case : 2 is larger than 0, therefore minimum.
or the formal way for any type of function : create the second derivative and see, if it is >0 (minimum) or <0 (maximum) for the extreme x.
in our case
f''(x) = 4
this is larger than 0 for all x, so the extreme point is a minimum.

A map's scale is 1 inch equals 50 miles. if new york city is 4 inches away from chelsea, ma, about how many miles is it from chelsea to new york city?
Answer:
200 miles
Step-by-step explanation:
Each inch represents 50 miles, so 4 times 1 inch will represent 4 times 50 miles.
4(1 in) ⇔ 4(50 mi)
4 in ⇔ 200 mi
It is about 200 miles from Chelsea to New York City according to the map.

Julia earned $2,000 during the month of September.
Use the paycheck statement to find the missing percent rates of the taxes Julia payed.
Based on the amounts Julia paid and the percentage rates, the missing amounts are:
$124 for social security. $29 for Medicare. 13% for federal income tax. 6% for state income tax. How much tax did Julia pay?Julia's social security taxes were:
= 6.2% x 2,000
= $124.
Medicare amount:
= 1.45% x 2,000
= $29
Federal income tax:
= 260 / 2,000 x 100%
= 13%
State income tax:
= 120 / 2,000 x 100%
= 6%
