Write the expression as a square of a binomial: 0.01x^4+y^2–0.2x^2y ^=square

That would be

(0.1x^2 - y)^2

Check:-

If we  expand this  (0.1x^2 - y)(0.1x^2 - y)

it =   0,01x^4 - 0.1x^2y - 0.1x^2y + y^2

= 0.01x^4  + y^2 - 0.2x^2y

associative property hopes this ! : )

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
