The first 3 figures in a pattern are shown. PART 1:Which of the following functions represents f(n), the number of small squares in figure n?

A) f(n) = 2n^2

B) f(n) = (n + 4) ^2

C) f(n) = 5n + 4

D) f(n) =n^2 + 4

PART 2:How many small squares will be in the 15th figure?

A) 60

B) 79

C) 229

D) 361

hehe is it d

Step-by-step explanation:

hehe

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
