I do questions like these a little different than most people so...
384/12= 32 (32 is 1% of his sales)
32*100= 3200
His total sales were $3200.
Answer:
x^2+x+1
Step-by-step explanation:
(3x^2+4x−1)+(−2x^2−3x+2)
Combine like terms
3x^2-2x^2+4x-3x-1+2
x^2+x+1
<h2><u>
Answer</u>
: </h2>
d. $25,140,000 in imports, $32,240,000 in exports
<h2><u>Step-by-step explanation:</u></h2>
Let x be the export worth and y be the import worth of Ireland.
Since, Balance trade = Export worth - Import worth
Then according to the question we have following equations :-
Multiplying equation (2) by 0.21, we get
Adding (1) and (3), we get
Substituting value of x in (2), we get
Hence, Ireland's import worth is 25,140,000 and export worth = $32,240,000
To solve this, you have to know that the first derivative of a function is its slope. When an interval is increasing, it has a positive slope. Thus, we are trying to solve for when the first derivative of a function is positive/negative.
f(x)=2x^3+6x^2-18x+2
f'(x)=6x^2+12x-18
f'(x)=6(x^2+2x-3)
f'(x)=6(x+3)(x-1)
So the zeroes of f'(x) are at x=1, x=-3
Because there is no multiplicity, when the function passes a zero, he y value is changing signs.
Since f'(0)=-18, intervals -3<x<1 is decreasing(because -3<0<1)
Thus, every other portion of the graph is increasing.
Therefore, you get:
Increasing: (negative infinite, -3), (1, infinite)
Decreasing:(-3,1)
Answer:211
