In explicit representation, a sequence is represented in terms of the first term while in recursive representation, a sequence is represented in terms of the previous term.
What are Recursive Formulas?
A recursive formula refers to a formula that defines each term of a sequence using the preceding term(s). The recursive formulas define the following parameters:
The first term of the sequence.The pattern rule to get any term from its previous term.What are Explicit Formulas?
Explicit formulas are always used to represent any term of the sequence, without writing the other terms of the sequence. The meaning of "explicit" is direct, something that can be directly found without knowing the other terms of sequence. The explicit formula helps to easily find any terms of the sequence, without knowing its previous term.
Eg, the sequence: 2, 4, 6, 8, 10, . . .
Explicit Representation An = 2 + 2(n - 1)
Recursive representation f(n) = 2 + f(n - 1)

If $9237.05 is put into an account paying %8.82/ a compounding yearly, how much interest will be earned after 16.7 years?
Answer:
$28,656.82
Step-by-step explanation:
I used the compound interest calculator
A = P(1 + r/100)ⁿ
where A = amount accrued, P = investment amount r = rate% and n = number of years
r = 8.82% = 8.82/100 = 0.082 so 1 + r/100 = 1.0882
[tex]\\A = P(1.0882)^{16.7} = \$37,893.87\\\\\mathrm {Interest} = \$37,893.87 - \$9237.05 = \$28,656.82[/tex]
Answer:
$28,656.82
Step-by-step explanation:
Annual Compound Interest Formula
[tex]\large \text{$ \sf I=P\left(1+r\right)^{t} -P$}[/tex]
where:
I = Total interest earned.P = Principal amount invested.r = Interest rate (in decimal form).t = Time (in years).Given:
P = $9237.05r = 8.82% = 0.0882t = 16.7 yearsSubstitute the given values into the formula and solve for I:
[tex]\implies \sf I=9237.05(1+0.0882)^{16.7}-9237.05[/tex]
[tex]\implies \sf I=9237.05(1.0882)^{16.7}-9237.05[/tex]
[tex]\implies \sf I=9237.05(4.1023777...)-9237.05[/tex]
[tex]\implies \sf I=37893.8685...-9237.05[/tex]
[tex]\implies \sf I=28656.8185...[/tex]
Therefore, the amount of interest that will be earned after 16.7 years is $28,656.82 (nearest cent).

Suppose two boxes of cereal contain the same amount of ounces but cost different amounts. Without computing, how can you determine which Siri will cost more per ounce of cereal? Explain.
Answer:
The one that costs more.
Step-by-step explanation:
Because you already know that they have the same volume (amount of ounces) and they are different prices, whichever one is more expensive has the higher cost per ounce. {You don't need to solve for a ratio or anything because they have the same number of ounces!!!}
Answer: If the number of ounces are the same, then the box that costs more will also cost more per ounce.
Two tents are in the shape of hemispheres, with circular floors. The ratio of their floor areas is 9: 12.25 . If the diameter of the smaller tent is 6 feet, what is the volume of the larger tent? Round to the nearest tenth.
The volume of the larger tent in the shape of hemispheres, with circular floors, is 89.8 cubic feet.
If the diameter of the smaller tent is 6 feet, then its radius is 3 feet. Solving for the area of its circular floor,
A = πr^2
A = π(3 feet)^2
A = 9π square feet
Using the ratio of the floor areas of the two tents, calculate the area of the circular floor of the larger tent.
9 : 12.25 = 9π square feet : x
where x = area of the circular floor of the larger tent
9x = 12.25(9π)
x = 12.25 π square feet
If the area of the circular floor of the larger tent is 12.25 π square feet, then solving for its radius,
A = πr^2
12.25 π square feet = πr^2
r = 3.5 feet
Hemisphere refers to half of a sphere and its volume is given by the formula V = 2/3πr^3, where r is the radius.
V = 2/3πr^3
V = 2/3 π (3.5 feet)^3
V = 89.79719002 cubic feet

Write a coordinate proof to prove that Δ A B C is an isosceles triangle if the vertices are A(0,0), B(a, b) , and C(2 a, 0) .
An isosceles triangle is one with two equal-length sides. ΔABC is an isosceles triangle.
What is the distance between two points ( p,q) and (x,y)?The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
D = √[(x-p)² + (y-q)²] units.
Given that the coordinates of the vertices of the triangle are A(0,0), B(a, b), and C(2a, 0). Now, to prove that the given triangle is an isosceles triangle we need to find the length of each side of the triangle.
AB = √[(x₂-x₁)² + (y₂-y₁)²]
= √[(a - 0)² + (b - 0)²]
= √(a² + b²)
BC = √[(x₂-x₁)² + (y₂-y₁)²]
= √[(2a - a)² + (0 - b)²]
= √(a² + b²)
AC = √[(x₂-x₁)² + (y₂-y₁)²]
= √[(2a - 0)² + (0 - 0)²]
= √4a²
= 2a
Since the length AB and BC are the same, while the length of AC is different, therefore, ΔABC is an isosceles triangle.

In this question,
Paul collects comic books. He has 20 books in his collection, and he adds 3 per month.
We need to find the number of months required to have a total of 44 books in his collection.
Let n be the required number of months.
From given information, we get an equation,
20 + 3n = 44
We solve above equation to find the required number of months.
20 + 3n - 20 = 44 - 20
