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:

$f(1)=1$
$f(n) = 5f(n-1)+4$

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

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

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

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

WidgCo is a company that produces and sells widgets. Let p denote the price per widget (measured in dollars), and let x be the m

Alecsey [184]

Answer:

The answer to this question can be defined as follows:

i) $\bold{p(x)= -5x^2+ 217x- 1,401} \\$

ii) x=22 units

iii) Maximum profit: 953.45

Step-by-step explanation:

Given value:

p(x) = 211 − 5x \\

C(x) = 1,401 + 16x

The formula for calculating the profit function value:

$\to \bold{P(x)= xp(x) - C(x)}$

$= x(211-5x)- 1,401 + 16x\\\\= 211x -5x^2-1,401+16x\\\\= -5x^2+ 217x- 1,401 \\$

The formula for calculating the value for maximum profit:

$p'(x) = - 10x + 217 =0$

$217= 10x\\\\x= \frac{217}{10}\\\\x= 21.7$

So, the production level is 22 units

Maximum profit:

$\to p(21.7)= - 5 (21.7)^2+217 (21.7) -1,401\\\\$

$=-5 (470.89) +217 (21.7) -1,401\\\\=-2354.45+ 4708.9-1,401\\\\= 953.45$
