What is the value of f(4)in the function below? f(x)=1/4•2^x

f(4) = 4

Step-by-step explanation:

F(x)=1/4•2^x

Let x = 4

F(4)=1/4•2^4

      = 1/4 * 2^4

      = 1/4 *16

      = 4

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
