Answer:

1) if we plug 2 in x, f (2)/(2-2)=100/0=undefined

2)ofcourse, when u plug -2 it makes it 0, f (-2)=0

3)the remainder being constant implies it is divisible by (x-1), 2x^2 (x-1)+4 (x-1), so ax^2=2x^2, a=2

I ONLY NEED HELP ON NUMBER 2
REY [17]
So, the area of a circle is a=pi r^2
so do that and get a=pi(4)
and since the circle touches the edge of the rectangle, the rectangle is 4 cm tall, so 4*8 is 32 and pi(4) is about 12.56, so 32-12.56 is 19.44, and I believe that is the answer. (19.4)

Answer:

1921579

Step-by-step explanation:

We can work this out by simply plugging the given value 2 into the functions in ascending order:

G(2) = 3(2) - 11\\= 6 - 11\\= -5

F(-5) = 2(-5)^2 + 4(-5) + 10\\= 2 * 25 - 20 + 10\\= 50 - 20 + 10\\= 40

H(40) = 3(40)^3 + 40^2 - 21\\= 3 * 64000 + 1600 - 21\\= 192000 + 1600 - 21\\= 1921579
