Answer:
Part 2:
The shape of a banana cut in 45° angle is that of a curve that is closed with the appearance of a flattened circle or an oval similar to an ellipse therefore having two focal points
The drawing of the angle cross section of a cylinder representing the banana is attached
Part 3:
When the banana is cut in half, perpendicular to the base of the banana, the shape formed is circular withe the center of the banana being about the same location as the center of the circle
The drawing of the perpendicular cross section of a cylinder representing the banana is
Step-by-step explanation:
3x-12+5-x=2x-7
2x-7 =2x-7
Means there are infinite solutions.
I need to answer two questions to ask again sorry
<span>x^2 - 9x + c
=x^2 - 2(x)(9/2) + (9/2)^2 is a perfect square
Therefore b = (9/2)^2 = 81/4
Ans: 81/4 </span>
Answer:
6x^2 - 2
Step-by-step explanation:
plug in f(x) into the g(x) formula given
g(f(x)) = (3x)^2 + 1
simplify
= 9x^2+2
plug in g(x) into the f(x) formula given
f(g(x)) = 3(x^2+1)
distribute
= 3x^2 +3
set g(f(x)) - f(g(x))
(9x^2+2) - (3x^2+3)
carry the negative
9x^2+2-3x^2-3
simplify by combining like terms
6x^2-2
