To find the formula to find radius, solve for r using the formula for circumference.
to solve:
1. divide each side by 2
2. you get
r = c/2
Answer:
121x2 + 36y2
Step-by-step explanation:
= (4x + 4)(x + 1)
= 4(x + 1)(x + 1)
= 4(x + 1)2 and is hence the fully factored form
not sure bout the rest though...... it may have mistakes in the question forms.
Step-by-step explanation:
A trinomial is an expression that has three terms.
Square trinomial
A square trinomial is simply a perfect square trinomial, and it is represented as:
\mathbf{a^2 + 2ab + b^2 = (a + b)^2}a2+2ab+b2=(a+b)2
Difference of square binomials
This is easily identified because, the terms of the square binomials are perfect squares.
The difference of square binomials is represented as:
\mathbf{a^2 - b^2 = (a + b)(a - b)}a2−b2=(a+b)(a−b)
Sums and difference of cubes
When cubes are added or subtracted, they can be expressed using the following
\mathbf{a^3 + b^3 = (a + b)(a^2 - ab + b^2)}a3+b3=(a+b)(a2−ab+b2) --- sum of cubes
\mathbf{a^3 - b^3 = (a - b)(a^2 + ab + b^2)}a3−b3=(a−b)(a2+ab+b2) --- difference of cubes

Answer:
93
Step-by-step explanation:
First differences increase by 4 each time. The given numbers are a quadratic sequence that can be described by 2n² -2n +9. The 7th term would be 93.
_____
First differences are ...
13-9 = 4, 21-13 = 8, 33-21 = 12, 49-33 = 16, 69-49 = 20
Second differences are ...
8-4 = 4, 12-8 = 4, 16-12 = 4, 20-16 = 4
When second differences are constant, the sequence can be represented by a second-degree polynomial function. The leading coefficient is half the value of the second differences.
You are right about the domain
it is all real values of x except 4
So about the range we must make x subject of the formular so we know the values of y in which g(x) is defined
