Answer:

first square = 3.6 x $10^{-1}$

Step-by-step explanation:

They are all multiplying so there is no need for parenthesis

(3.8 * 10³) * (9.4 * $10^{-5}$ )

3.8 * 10³ * 9.4 * $10^{-5}$
35.72 * $10^{-2}$

35.72 =~ 36

Everytime you elevate a number, it's the same as...
3 * 10² = 100 * 3 = 300

0.3 * 10³ = 1000 * 0.3 = 300

so then...

36 * $10^{-2}$ = 3.6 * $10^{-1}$

I need assistance with "What does the area of the rectangle depend on", the graph section, and the relationship section.

DanielleElmas [232]

The area equation here is:

$A=2w^2$

That means that the area depends on the width measurement of the rectangle.

To graph a quadratic function you have to see if the parabole is positive and the transformations, in this case, are positive and have a multiplication by two, which means that the graphics in x=1 and x=-1 will be y=2

Finally, you can conclude that there, you have a relationship between the area and the width of the rectangle because is a quadratic relationship and the area will increase in a quadratic form according to the increase of the width.
