2. Use the information to answer the following questions. Anna starts a website for celebrity gossip. Before launching the website, she has
her friends and family sign up. Then, she uses the equation shown to estimate
the number of users, y, who will have signed up x weeks after she officially
launches the website.

y=74(1 055)

Part A: Anna's brothers Sam and Tony disagree on the rate of growth of
Anna's equation. Sam believes the rate of growth is 0.055% and Tony
believes the rate of growth is 5.5%. Who do you agree with and why?
A. Sam
B. Tony
Explain:
Part B: How many users should Anna expect after the first 4 months?

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

they are simplified

step-by-step explanation:

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

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
