Answer:

490,000

Step-by-step explanation:

since 9 is the number we are rounding we look at the next number to the right and either we round up or down depending upon that number. since it is a 3 we round down but if it was a 5 or higher that number would be 500,000

Suppose that the cost of producing n pairs of shoes is given by the expression c(n)=30+5n. the average cost of producing a pair

makkiz [27]

<h3>Given</h3>

$c(n)=30+5n\\a(n)=\dfrac{c(n)}{n}$

$\dfrac{d}{dn}(a(n))\quad\text{at n=10}$

<h3>Solution</h3>

$\dfrac{d}{dn}(a(n))=\dfrac{d}{dn}\left(\dfrac{30+5n}{n}\right)=\dfrac{d}{dn}\left(30n^{-1}+5\right)\\\\=-30n^{-2}\\\\=-30\cdot 10^{-2}\qquad\text{at n=10}\\\\=-0.30$

The derivative of the average cost function at n=10 is -0.30.

Combine each pair of equations solve the combined equation 3j +14=-5z-10j=5z

ArbitrLikvidat [17]

Given data:

The first equation is 3j +14=-5z.

The second equation is -10j=5z .

Add both the equations.

$\begin{gathered} (3j+14)+(-10j)=-5z+5z \\ -7j+14=0 \\ 7j=14 \\ j=2 \end{gathered}$

Substitute 2 for j in the first equation.

$\begin{gathered} 3(2)+14=-5z \\ 20=-5z \\ z=-4 \end{gathered}$

Thus, the value of j is 2 and z is -4.
