The sequence of numbers when x₁ = 1 of the given series [tex]x_{n+1}[/tex] = [tex]{x_{n}}^2[/tex] + xₙ will be 1, 2, 6, 42,...
What is a series?A sequence's series is the total number of terms in the sequence.
A series follows some pattern for example if you take data set of natural numbers then there will be a sequence of that data and something will be due to that we can form that series.
As per the given series,
[tex]x_{n+1}[/tex] = [tex]{x_{n}}^2[/tex] + xₙ
Substitute,n = 1 into
x₂ = x₁² + x₁
x₂ = (1)² + 1 = 2
Substitute,n = 2
x₃ = x₂² + x₂
x₃ = 2² + 2
x₃ = 6
Substitute,n = 3
x₄ = x₃² + x₃
x₃ = 6² + 6
x₃ = 42
Hence "The sequence of numbers when x₁ = 1 of the given series [tex]x_{n+1}[/tex] = [tex]{x_{n}}^2[/tex] + xₙ will be 1, 2, 6, 42,...".

We know that:
$66.75 = 3 shirtsTo solve: Find the cost for 1 shirt.
Solution:
$66.75 = 3 shirts=> 1 shirt = $66.75/3=> 1 shirt = $22.25Hence, the cost for 1 shirt is $22.25.

Answer:
40+4.5p=112, and 16
Step-by-step explanation:
Roger always starts off with the same $40. Then, he gets $4.5 for every pair of shoes he sells. So, if the number of shoes sold is p, we then have the equation:
40+4.5p=112
The next part of the question asks for us to solve this equation, basically. We subtract 40 from both sides:
4.5p=72
p=72/4.5 (Divide both sides by 4.5)
p=16

A swimming pool is filled at a constant rate.When half full the pool has had 7500 litres poured into it. a)How much will the pool hold when full?b) what fraction has been filled when 5000 litres of water are in the pool?
Answer:
a) 15 000 litres
b) 1/3
Step-by-step explanation:
a) Since the pool has 7500 litres when half full, it must have double that when full.
7500 * 2 = 15 000
b) Since the full pool is 15000, when the pool has 5000 litres it has 5000 out of 15000, hence the fraction 5000/15000 which simplifies to 1/3.
Simplification: divide the numerator and denominator by 5000.
Answer:
a) 15000
b) 1/3

solve for x. round to nearest hundredth. PLS HELP. will award brainliest
Answer:
[tex]x[/tex] = 6.34 to the nearest hundredth
Step-by-step explanation:
The three sides of a right-angled triangle have specific names:
The hypotenuse (H) is the longest side. It is opposite the right angle.The opposite side (O) is opposite the angle in question.The adjacent side (A) is next to the angle in question.The 3 trigonometric ratios are:
[tex]sin(\theta)=\frac{O}{H} \\\\cos(\theta)=\frac{A}{H} \\\\tan(\theta)=\frac{O}{A}[/tex]
For the given triangle we are given the angle, the hypotenuse, and need to find the side that is OPPOSITE to the angle.
Therefore, we would use the trig ratio: [tex]sin(\theta)=\frac{O}{H}[/tex]
Substituting the values from the triangle: [tex]sin(25)=\frac{x}{15}[/tex]
Multiply both sides by 15: [tex]15sin(25)=x[/tex]
Therefore, [tex]x[/tex] = 6.339273926...
So [tex]x[/tex] = 6.34 to the nearest hundredth
How long would it take before the Hendersons would recover their costs if they chose to do it themselves over the professional service? a. 5 months b. 9 months c. 10 months d. 6 months.
To solve the problem we will calculate the cost in both cases.
Hendersons will be able to recover their costs if they chose to do it themselves in 2 months.
Given to us
Do-It-Yourself Option
$250 for the lawnmower$135 for edger Includes mowing and edging $69 for hedge trimmer lawn, trimming the bushes, and $25 for rake, raking the leaves.Professional Service
$75 for the first month$45 per month after the initial visitTotal cost if they do it themselves,Total cost if they do it themselves = $250 + $135 + $69 + $25
= $479
So, it will take $479 for them if they start doing it by themselves.
Total cost if they take Professional Service for a yearTotal cost if they take Professional Service = Initial fees + monthly fee
= $75 + (11 month x $45)
= $570
So, it will charge $570 if they take Professional Service for a year.
Difference between the CostDifference between if they do it themselves and if they take a professional service
= $570 -$479
= $91
So, if they try to do it themselves they will save $91, which is approximately two times the monthly fee of the professional service.
Hence, Hendersons will be able to recover their costs if they chose to do it themselves in 2 months.

Rehan proved by mathematical induction that for all
the positive integers, n°
+ 2n is divisible by 3. Can
you find an integer counterexample to show that
this statement is not true? Explain.
If your teacher wants you to find a positive integer for n that will make [tex]n^3+2n[/tex] not divisible by 3, then you'll be searching for quite a while.
This is because Rehan is correct in the statement that [tex]n^3+2n[/tex] is divisible by 3 for any positive integer n.
n = {1,2,3,...}
For example, if n = 5, then
[tex]n^3+2n = 5^3+2(5) = 125+10 = 135[/tex]
That is divisible by 3 because 135/3 = 45 is a whole number result without any decimal or fractional extras.
---------------
Here's the proof that Rehan probably used or set up.
Base case: Plug in n = 1 to find that [tex]n^3+2n = 1^3+2(1) = 3[/tex] which is definitely divisible by 3.
Inductive step:
Assume that [tex]k^3+2k[/tex] is divisible by 3 for some integer k > 1.
The goal is to then show it leads to [tex](k+1)^3+2(k+1)[/tex] is also divisible by 3.
Skipping a bunch of steps, you should find that [tex](k+1)^3+2(k+1) = (k^3+2k) + 3(k^2+k+1)[/tex]
The first part k^3+2k is already assumed to be a multiple of 3, so we don't need to worry about it. The second part 3(k^2+k+1) is also a multiple of 3 because 3 is a factor.
Summing any two multiples of 3 gets us another multiple of 3.
Therefore, this concludes the proof that Rehan would have done. There are probably alternative proof methods he could have used, but he likely followed these steps or similar when doing the induction proof.
---------------
Long story short, the fact that the statement [tex]n^3+2n \text{ is divisible by } 3[/tex] is proven to work with any integer n from the set {1,2,3,...} means that we cannot find a counterexample.

What's distributive property?
Distributive property is a property of multiplication that is typically in the form a(b + c), where a is the number being "distributed" to b and c. (This means you multiply a by b and a by c)Given the information above, let's distribute 2 to m and 2n.
