If f(1) = 1 and f(n) = 5f(n-1) + 4 then find the value of f(5).
klasskru [66]

Answer:

f(5)=1249

Step-by-step explanation:

Given:

  • f(1)=1
  • f(n) = 5f(n-1)+4

\implies f(2) = 5f(1)+4=5(1)+4=9

\implies f(3) = 5f(2)+4=5(9)+4=49

\implies f(4) = 5f(3)+4=5(49)+4=249

\implies f(5) = 5f(4)+4=5(249)+4=1249

14. Given: 5x + 4y = 24, x + 7y= 11; Prove: y= 1<br> Statements<br> reasons
Semenov [28]

Answer:

Step-by-step explanation:

We can use the process of elimination as

5x + 4y = 24

5(x + 7y = 11) —>          5x + 35y = 55

5x + 4y = 24

-(5x + 35y = 55)

—————————

-31y = -31

-31y/-31 = -31/-31

y=1
