Answer:
3781
Step-by-step explanation:
80 hours × $18=$1440 for labor. 1440+15%(1440×.15)=$216.00 + material cost=$2125
(2125.00+1440.00+216=3781)
By implicit differentiation:
<span>(x(dy/dx) + y)e^(xy) = 0 </span>
<span>Note that when differentiating e^(xy), apply chain rule. When differentiating xy, use product rule. Also: When differentiating y w/respect to x, think of that as if you are differentiating f(x). </span>
<span>Then, substitute (1,ln(2)) and solve for dy/dx. </span>
<span>(1(dy/dx) + ln(2))e^(1ln(2)) = 0 </span>
<span>((dy/dx) + ln(2))e^(ln(2)) = 0 </span>
<span>Note that e^(ln(2)) = 2 since e and ln are inverse of each other. </span>
<span>2((dy/dx) + ln(2)) = 0 </span>
<span>dy/dx + ln(2) = 0 . . . . You get this expression by dividing both sides by 2 </span>
<span>dy/dx = -ln(2) . . . . . . .Subtract both sides by ln(2) </span>
<span>Therefore, dy/dx = -ln(2) </span>
<span>I hope this helps!</span>
Answer:
I believe that it is C.
Step-by-step explanation:
Amanda's speed is 9 mph because 18 divided by 2 is 9.
Marcos speed is 8 mph because you can work backwards from the graph from the second point of (2, 16) to (1, 8) and find the difference of 1, and 8.
The slope is therefore 8.
Amanda's speed is 9 mph and Marco's speed is 8 mph. I think you know the answer from the previous statement.
Step 1: If there is a common factor, factor out the GCF. Step 2<span>: Identify the number of terms: (i) If polynomial has two terms, convert polynomial into difference of two squares or sum of two cubes or difference of two cubes.</span>
