Answer:

6 for $37.50 has the same price

Step-by-step explanation:

The price per wand is found by dividing the price by the number of wands.

8 for $50 ⇒ $50/8 = $6.25 per wand

4 for $20 ⇒ $20/4 = $5.00 per wand <em>not the same</em>

6 for $37.50 ⇒ $37.50/6 = $6.25 per wand <em>is the same price</em>

10 for $65 ⇒ $65/10 = $6.50 per wand <em>not the same</em>

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.

Lemur [1.5K]

Answer:

9526

Step-by-step explanation:

simplify 3^3+27

4+3*6(4-27)^2

simplify: 4-27+ -23

4+3*6(-23)^2

since the power of 2 is even it will be a positive

4+3*6*23^2

simplify: 23^2 to 529

4+3*6*529

simplify 3*6 to 18

4+18*529

then simplify 18*529 to 4+9522

and 4+9522= 9526
