If f(n)=5^n then what is f(4)

1 answer:

5 0

All you have to do is plug in 4 where n is

In other words n = 4

So...

F(n) = 5^n
F(4) = 5^4 or (5 x 5 x 5 x 5)
F(4) = 625

Answer:

Step-by-step explanation:

You start off by rewriting the equation:

$2(x-7)=0.2(x+2)+5.11\\$

Then you have to factor:

$2x-14=0.2x+0.4+5.11$

Then you subtract the 0.2x:

$1.8x-14=0.4+5.11$

Add the positives on the right:

$1.8x-14=5.51$

Add 14:

$1.8x=19.51$

Divide:

$x=10.84$

You get x is approximately equal to 10.84
