Step-by-step explanation:
Use the compound interest formula:
A = P( 1 + r/n)^nt
A is the amount at the end
P is the principal or original amount.
R is annual rate as a decimal (you have to convert)
N is the # of compounding periods in a year (quarterly means 4)
T is time in years
A = 500( 1 + 0.0475/4)^(4×20)
This would be $1285.64 when fully computed.

Which is the best description of an extraneous solution?
A solution that results in a true statement when substituted back into the original equation.
A solution that results in a false statement when substituted back into the original
equation.
A solution that is false for all absolute value equations.
A solution that is true for all absolute value equations.
Answer:
A solution that results in a false statement when substituted back into the original equation.
Step-by-step explanation:
An extraneous solution is one that arises in a solution of equations, but which on closer inspection is not a solution to the original equation. Therefore, they imply an error in the development of the solution of the equation, so they cannot be taken as a valid solution since, when replacing the result with the missing variable, the equation does not obtain the desired result.

Factorise x2 + 4x + 3
Answer:
(x + 1)(x + 3)
Step-by-step explanation:
Given
x² + 4x + 3
Consider the factors of the constant term (+ 3) which sum to give the coefficient of the x- term (+ 4)
The factors are + 1 and + 3, since
1 × 3 = 3 and 1 + 3 = 4, then
x² + 4x + 3 = (x + 1)(x + 3)

How do you expand double brackets
Answer:
Step-by-step explanation:
Expanding double brackets is easy. Let me give u an example :
(x+5)(x+1)
so the way i do it is
1.Write the second bracket (x+1) twice :
(x+1) (x+1)
2. split the first bracket (x+5) like this :
x(x+1) +5(x+1)
3. Simplify
x*x = x²
x*1 = 1x
5*x = 5x
5*1 = 5
x² + 1x + 5x + 5 = x² + 6x + 5
so the final answer is gonna be x² + 6x + 5
in order to factorize it, u basically do the following :
1. Find two numbers, that multiply to give the last number (a.k.a 5 ) and add to give the middle number (a.k.a 6) The middle number is the sum, and the last number is the product.
so u write all the combo's that make the number 5 :
1 x 5
The two number's are gonna be 1 & 5, because 1 + 5 = 6 (the sum) and 1 x 5 = 5 (the product)
This example is easy since it doesn't include any negative numbers, so u just do = (x+1) (x+5) or (x+5) (x+1) same thing ;-;
I think u should just ask a teacher or watch a tutorial or smthn, this is like the worst explanation ever. But yeah once u know the method, you'll find expanding double brackets rly easy.
Given that f(x) = x2 – 12x + 27 and g(x) = x – 9, find f(x) · g(x) and
express the result in standard form.
Answer:
[tex]f(x)\cdot g(x)=x^3-21x^2+135x-243[/tex]
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=x^2-12x+27\text{ and } g(x)=x-9[/tex]
And we want to find:
[tex]f(x)\cdot g(x)[/tex]
So, by substitution:
[tex]=(x^2-12x+27)\cdot (x-9)[/tex]
Distribute:
[tex]=(x^2-12x+27)(x)+(x^2-12x+27)(-9)[/tex]
Multiply:
[tex]=(x^3-12x^2+27x)+(-9x^2+108x-243)[/tex]
Rearrange:
[tex]=(x^3)+(-12x^2-9x^2)+(27x+108x)+(-243)[/tex]
Combine like terms:
[tex]=x^3-21x^2+135x-243[/tex]
Hence:
[tex]f(x)\cdot g(x)=x^3-21x^2+135x-243[/tex]
