write a function that models the total number of blocks in terms of n.
a. f(1) = 2; f(n) = f(n − 1) + 2n; for n > 2
b. f(1) = 2; f(n) = f(n − 1) + 4n; for n > 2
c. f(1) = 1; f(n) = f(n − 1) + n; for n > 2
d. f(1) = 1; f(n) = f(n − 1) + 2n; for n > 2

first one is a: renaming a fraction. second one is c: de-c

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
