Recursive formula= a(n)=a(1)(n-1)+d
a(n)= 9(n-1)+2
explicit formula= a(n)= a(1)+(n-1)d
a(n)= 9+(n-1)2
12th row= a(12)=9+(12-1)2
a(12)=9+11(2)
a(12)=9+22
a(12)=31
Area =
Area = 22/7 x 10 x 10
Area = 314 in^2
(the answer is option A, its rounded)
Hope this helps
Answer:
Domain(x): -2,2,3
Range(y): -1,4,5,6
(I put them in order numerically)
Step-by-step explanation:
The Domain is all the x values of the points given. It's always the first number of a point.
The range is the y values, it's always the second number given in a ordered pair!
Hope this helps! :)
Think you gotta add them all up them divide by how many numbers their are

Answer:
x² -11x +18 = (x -9)(x -2)
Step-by-step explanation:
The x-coefficient is the sum of the constants in the binomial factors; the constant term is their product. It usually works well to look for factors of the constant that have the right sum. Here, both must be negative.
18 = (-1)(-18) = (-2)(-9) = (-3)(-6)
The factors -2 and -9 have a sum of -11, so those are the binomial constants of interest. The factorization is ...
x² -11x +18 = (x -9)(x -2)
