Identify the sequence as arithmetic or geometric. f(n+1)=17 f(n), for n≥1 and f(1)=49

Step-by-step explanation:

f(1) = 49

f(n+1) = 17f(n)

n = 1 ; f(1+1) = 17* f(1)

           f(2) = 17 * 49 = 833

This is a geometric sequence. Each term is got by multiplying 17 with the previous term, Which means 17 is the common ratio

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
