Step-by-step explanation:

Similar figures have same ratio of corresponding sides.

Set up ratios and solve for x.

#1

  • x / 54 = 6 / 36
  • x / 54 = 1/6
  • x = 54/6
  • x = 9

#2

  • x / 4 = 99 / 11
  • x / 4 = 9
  • x = 4*9
  • x = 36

#3

  • x / 10 = 6 / 60
  • x / 10 = 1/6
  • x = 10/6
  • x = 5/3

#4

  • x / 4 = 28 / 7
  • x / 4 = 4
  • x = 4*4
  • x = 16

If f(1) = 6 and f(n) = f(n − 1) +3, then f(7) =<br> (1) 10 (2) 24 (3) 15<br> (4) 18
Juliette [100K]

Answer:

24

Step-by-step explanation:

f(n) = f(n − 1) + 3

if n = 7 => f(7) = f(7-1) + 3 = f(6) + 3

if n = 6 => f(6) = f(6-1) + 3 = f(5) + 3

if n = 5 => f(5) = f(5-1) + 3 = f(4) + 3

if n = 4 => f(4) = f(4-1) + 3 = f(3) + 3

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

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

if f(1) = 6 then f(2) = 9

f(3) = 12

f(4) = 15

f(5) = 18

f(6) = 21

f(7) = 24
