Answer:

f(3)=21

Step-by-step explanation:

f(1)=3

f(n)=2f(n-1)+3

n=2

f(2)=2f(2-1)+3

f(2)=2f(1)+3

f(2)=2*3+3

f(2)=6+3

f(2)=9

n=3

f(3)=2f(3-1)+3

f(3)=2f(2)+3

f(3)=2*9+3

f(3)=18+3

f(3)=21

Which measurement is the best estimate for the length of a clothespin? 9 mm 9 cm 9 m 9 km?
s344n2d4d5 [400]

The answer would 9 cm. All of the given choices are wrong since the measurement maybe too big or too small. Like for 9 millimeter, it would be too small for a clothespin. While 9km is too big for a clothespin, there is no such thing as a 9km clothespin. While 9 m is also too big. The approximate size of a clothespin is 3 inches, when we convert it to cm, it will be 7 cm. So 9 cm is a best approximate.
