Please help me with my math I’m so bad at this

Mathematics

Answer:

9

Step-by-step explanation:

(-9)^1/3 * (-81)^1/3

We can rewrite -81 as 9 * -9

So it can be rewritten as:

(-9)^1/3 * (9*-9)^1/3

Since they are all raised to the 1/3, we can combine the bases:

(-9*9*-9)^1/3 =

(9*9*9)^1/3, because the two negatives turn into a positive:

So this is basically:

(9^3)^1/3 = 9^1 = 9

An online company sells handmade samurai katana swords. The website costs $ 390 a month to maintain. Each katana costs $ 195 to
Arada [10]

Answer:

The correct answer is the linear model would be y = 500x - 390 where x is the number of swords sold in a month and y is the net monthly profit; B. 4.96 ≈ 5 swords monthly.

Step-by-step explanation:

Let x number of swords are sold per month.

Cost price of the swords per month is $ 195x.

Fixed cost to maintain the website per month is $390.

Total cost incurred per month is $ (195x + 390).

Selling price per katana is $695.

Total selling price of x swords per month is $695x.

Therefore, Net monthly profit y =695x - (195x + 390)

⇒ y = 695x - 195x - 390

⇒ y = 500x - 390

Thus the linear model would look like y = 500x - 390 where x is the number of swords sold in a month and y is the net monthly profit.

B. Now, given monthly profit y = $2090.

Thus the number of swords needed to be sold is

2090 = 500x - 390

⇒ 2480 = 500x

⇒ x = 4.96

A minimum of 5 swords need to be sold to get a monthly profit of more than $2090.
