First six shipments:
tester [92]
For problems like this, we need to find the pattern between the set of numbers to create a general equation for f(x). Given that x is the shipment number, let us first observe the first six shipments' behavior.
1  10 |
2  16 = 10 + 1(6) |
3  22 = 10 + 2(6) |
4  28 = 10 + 3(6)|  
5  34 = 10 + 4(6) |
6  40 = 10 + 5(6) |

From these, we can observe that given x number of shipments, the total number of objects would be 10 + (x-1)6 = 10 + 6x - 6 = 6x +4. Thus, given f(x), we have 

f(x) = 6x + 4
Answer: f(x) = 6x + 4

faltersainse [42]

Answer:

30units,2900

Step-by-step explanation:

Given that Country Motorbikes Incorporated finds that it costs $400 to produce each motorbike, and that fixed costs are $1600 per day.

The price function is p(x) = 700 − 5x, where p is the price (in dollars) at which exactly x motorbikes will be sold.

If x units are produced and sold we have

Costs for x units = variable costs *x +Fixed costs = 400x+1600

Sales revenue = no of units sold * price = x(700-5x) = 700x-5x^2

Profit funciton = P(x) = Sales revenue - Total cost

= 700x-5x^2-400x-1600\\=300x-5x^2-1600

To get maximum profit we use derivative test I derivative =0 and II derivative =negative

P'(x) = 300-10x\\p"(x) = -10

Producing 30 units will maximize the profit.

Max profit

=P(30) = 2900

mestny [16]

60 % less customers than the typical customer count in the original store at any given time.

The correct option is A.

<h3>What is Average number?</h3>

The total number of values in a given set divided by the sum of all the values is how an average is calculated. The arithmetic mean is another name for it. To get the average, let's look at some basic facts. The available values are 1, 2, 3, 4, and 5. Average is the total sum of all values or the total number of values.

<h3>According to the given information:</h3>

At any given time, the original business had an estimated average of 45 customers. According to the manager of the new store, on average 90 customers each hour—or 1.5 customers per minute—enter the establishment.

Additionally, the manager calculates that each customer spends an average of 12 minutes inside the shop.

According to Little's law, the new business has customers inside on average at all times.

, N=rt=(1.5)(12)=18

So,

= ((45−18)/45) ×100

=60

60 % less customers than the typical customer count in the original store at any given time
