Answer:
3x^2 + 8
Step-by-step explanation:
Given functions,
f(x) = 3x + 8 ----(1)
g(x) = x^2 -----(2)
Since,
(fog)(x) = f( g(x) ) ( Composition of functions )
=f(x^2) ( From equation (2) )
=3x^2 + 8 ( From equation (1) )
Hence,
(fog)(x)=3x^2 + 8
Step-by-step explanation:
Answer:
<h2>f(0) = -4</h2>
Step-by-step explanation:

Answer:
Step-by-step explanation:
Area of shaded region= area of rectangle- area of triangle
Area of rectangle= l×b
=9×3
= 27m²
Area of triangle=
b×h
=
×3×3
=
⇒4.5
Area of shaded region= area of rectangle- area of triangle
=27-4.5
=22.5m²
Answer:
use a2+b2=c2 so
Step-by-step explanation:
11(squared)+b(squared)=13(squared)
=121+b2=169
-121. -121
b2= 48
square root 48
Side B= 6.928
and then just round 6.928
hope this helped
