I did not catch well, but i think you already got your answers. Let me explain. For the first part you got your notation right: for 0.0045 the correct scientific notation is 4.5 x 10^-3. Now the second part, the answer would be the first one, the notation that you are giving is the one who corresponds to <span>4.5 x 10^-2, the first option you have. Hope it helps</span>
Idk really I enjoyed this mathematics
Answer:
The amount of change he should received is
$100 - $56.875
= $43.125
= $43.13
Step-by-step explanation:
Length of window trim = 32 and 1/2 ft
Cost per foot = $1.75
Amount paid = $100
Total cost of window trim = 32.5×1.75 = $56.875
The amount of change he should received is
$100 - $56.875
= $43.125
= $43.13
In any equation there is a variable (usually x). In a quadratic equation there is a lot involved.
-B (+or-) sqrt of b^2 - 4 x A x C
________________________ divide it by
2 x A
There is usually an original equation that looks like: Ax^2 + Bx + C = 0 Use the variables from the equation to the left to fill the upper equation. (You can also look up a better formula if confused).
