(f-g)(x) = 4x²-2x-12 which,evaluated at x=4, gives 64-8-12=44
Answer: V = 8x^3-80x^3 +200x
Domain 0<x<5
Step-by-step explanation:
Dimension of cardboard = 10 by 10
Let the length of box = 10-2x
Let the width of box = 10 - 2x
Let the height of box be =x
Volume = l×w×h
V = (10-2x)×(10-2x)×x
V= 100 - 40x +42 × x
V= 8x^3 -80x^2 +200x
241/4 or 60.25......................................
c ≈ 16.7 ( to 1 dec. place ) → d
since triangle ABC is right use the cosine ratio to find c
cos33° = 
= 
multiply both sides by c
c × cos33° = 14 ( divide both sides by cos33° )
x = 
≈ 16.7 ( to 1 dec. place )
Of course Lebron is black, lol.
