Use the function below to find f(4). F(x)=1/3•4^x

  f(4) = 85 1/3

Step-by-step explanation:

Put 4 where x is and do the arithmetic.

  f(4) = (1/3)4^4 = (1/3)(256)

  f(4) = 85 1/3

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
