Answer:
Step-by-step explanation:
1.
The cash flow from operating activities is = $28000.
Working Note:
Net Income $20000
Depreciation expense $3000
Increase in accounts receivable ($2000)
Increase in accounts payable $4000
Decrease in inventory $3000
Net Cash Flow from Operating Activities = 20000 + 3000 – 2000 + 4000 + 3000
Net Cash Flow from Operating Activities = $28000
2.
The cash flow from investing activities = $6000.
Working Note:
Proceeds from sale of equipment $6000
Net cash flow from investing activities = $6000
3.
The cash flow from financing activities = - $2000 or ($2000)
Working Note:
Payment of dividends ($2000)
Net Cash flow from financing activities = - $2000 or ($2000)
The value of the derivative at the maximum or minimum for a continuous function must be zero.
<h3>What happens with the derivative at the maximum of minimum?</h3>
So, remember that the derivative at a given value gives the slope of a tangent line to the curve at that point.
Now, also remember that maximums or minimums are points where the behavior of the curve changes (it stops going up and starts going down or things like that).
If you draw the tangent line to these points, you will see that you end with horizontal lines. And the slope of a horizontal line is zero.
So we conclude that the value of the derivative at the maximum or minimum for a continuous function must be zero.

Answer:
Slope = Rise over Run
Rise = 2
Run = 3
Slope = 2/3
Let me know if this helps!
Answer:
21
Step-by-step explanation:
Let x represent the number of dimes and y represent the number of nickels. The total number of coins is 37; this gives us the equation
x+y = 37
Each dime is worth ten cents, or 0.10, and each nickel is worth five cents, or 0.05. The total amount of money is given by
0.10x+0.05y = 2.65
This gives us the system

To solve this, we will use substitution. We will isolate x in the first equation:
x+y=37
Subtract y from each side:
x+y-y = 37-y
x = 37-y
Substitute this into the second equation:
0.10(37-y)+0.05y = 2.65
Using the distributive property,
0.10(37)-0.10(y)+0.05y = 2.65
3.70-0.10y+0.05y = 2.65
Combining like terms,
3.70-0.05y = 2.65
Subtract 3.70 from each side,
3.70-0.05y-3.70 = 2.65-3.70
-0.05y = -1.05
Divide both sides by -0.05:
-0.05y/-0.05 = -1.05/-0.05
y = 21
There were 21 nickels.
