Let g(x)=2x and h(x)=x^2+4. evaluate (g•h)(3).

answer:

26

step-by-step explanation:

g(x)= 2x

h(x)= x^2+4

now (g.h)(3) can be written as g(h( i.e.

(g.h)= 2(h(x))

        = 2(x^2 + 4)

        = 2x^2 + 8

now

(g.h)(3)= 2(3)^2 + 8

            =   2(9) +8

            =18 + 8

            =26

!

because they could drop even lower..

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
