Answer:
Step-by-step explanation:
1) Replace f(x) with y: y = 19/x^3
2) Interchange x and y: x = 19/y^3
3) Solve this result for y: xy^3 = 19, or y^3 = 19/x, or
y = ∛[19/x]
-1
4. Replace this y with the label f (x) = ∛[19/x]
The greatest possible error is 0.5lb.
The GPE is one half of one unit, no matter which unit you're using or the margin of error you have.
Since we are using pounds in this case, the GPE is 0.5 pounds.
<u>ANSWER</u>
<u>EXPLANATION</u>
The given function is
We make the coefficient of 
unity by factoring 
out of the last two terms to obtain;
We now add and subtract half the coefficient of 
multiplied by a factor of 6 to obtain;
We now factor 6 out of the last two terms to get;
The quadratic trinomial in the parenthesis is now a perfect square.
Hence the vertex form of the polynomial is
0.9<span>% of </span>603<span> = 5.43
so estimated is 5.40</span>
BC is greater than AC is correct. If you need help with the construction, feel free to ask.
And maybe you're not clear with the options, because you've written BC two times which is necessarily not an answer/option.
