Kim owns a start-up business that creates software apps. The graph shows her business's revenue function. What is the correct
BaLLatris [955]

The business can turn a profit by cutting costs.The sum of the units sold times the price per unit is the revenue.Multiply the output level by the pricing function to get the revenue function.

How can the business save expenses?

  • Total revenue is important because it gives businesses a high level understanding of the relationship between pricing and consumer demand for an additional unit of product at any given time. The total revenue formula is simply: TR = P * Q (Total Revenue = Price * Quantity Sold)

changing the personnel.

  • using less expensive substitute raw materials.
  • enhancing the pace of production.
  • Profit for a business is the amount of income that remains after all expenses are paid.
  • The profit would increase if these costs were decreased because less income would be needed to pay for manufacturing costs.
  • production crew salaries and raw materials
  • The entire income generated from the sale of x units of the product is represented by the revenue function R(x).
  • The total profit made from producing and selling the x units of the product is represented by the profit function, P(x).
  • Price of goods or services divided by the quantity or number of clients equals revenue.
  • For instance, if a business sells 10 computers for $50,000 each, it may figure out its gross income using the following formula:Gross revenue = ₹50,000 × 10 = ₹500,000.

Describe a real life multiplication situation for which an estimate makes sense
Blizzard [7]
Let's say we're at the store and you want to buy 10 boxes of cookies for a party. Each box of cookies cost 4.89(counting tax), you don't know if you have enough money to buy the cookies with the $65.00 you have with you. You could round the price up to $5.00 and do more simple multiplication. Your total would estimate about $50.00. Now you know you have more than enough money to buy cookies. I hope that makes sense. :)

Michael says that 5(1/5^3) = 5(5^3) is his answer correct explain.
kow [346]
Answer: His answer is wrong

Explanation:

5(1/5^3) = 5(1^3/5^3) = 5(1/125)
5(5^3) = 5(125)

Let’s compare:

5(1/125) < 5(125)

Because 1/125 is smaller 125
Thus, it is not equal.

Answer number 14. It’s very difficult for me and i need some help.
professor190 [17]

Answer:

1201.2 in (100.1ft)

Step-by-step explanation:

A scale model represents a ratio. All sides must be shrunk or increased based on a constant value. In this case the ratio of the model is 1/13 the size of the original giving us a 1:13 ratio. So each side of your scale model must be multiplied by 13 to find the real value of the side.

First convert all units to inches then divide the width of the real windmill by the width of the scale model (both in inches) you will see the answer is 13. Multiply the inch values of all sides of your model by 13 and this gives you the proportional value of each side of the real windmill in relation to the scale model.
