Answer:

Option B is correct.

Step-by-step explanation:

A proportional relationship is a relationship between two variables where the ratio between the two variables is always the same.

Divide b/a for each option, the option having same ratio for the complete tables have proportional relationship

a)

9/3 = 3

12/4 = 3

20/5 = 4

Need the answer to number 8 pls
Rama09 [41]
We can split it up into

( \frac{x^4+2x^2}{x^2+2})+(  \frac{1}{x^2+2} )= (\frac{x^2(x^2+2)}{x^2+2})+(  \frac{1}{x^2+2} )x^2+\frac{1}{x^2+2}
I see you were supposed to use synthetic division

not sure what the 'related function is'
but as |x| approaches positivie infinity, y approaches positive infinity
as |x| approaches negative infinity, y approaches positive infinity

for the original function
as x approaches positivie infinity x^2+ \frac{1}{x^2+2} approaches positive infinity
as x approaches negative infinity x^2+ \frac{1}{x^2+2} approaches positive infinity
this is due to the x^2 term making it positive

The base of a box is a rectangle. The width of the box is half its length. The height of the box is 0.5m. Find the volume of the
Ivan
Let x be the length and y be the width.
We know already 
y= \frac{x}{2}
Area of the base xy
Area of the sides: (x+y)0.25
We get the equation xy=0.25(x+y)-1.08
We will solve the system:
y= \frac{x}{2}\\xy=0.5(x+y)-1.08
The above system has  no real solution, please check your values.
