Which function is a quadratic function? F(x) =2x^2, g(x) =5x^3,k(x)=-x,b(x)=-9x^4

Mathematics

Katen [24]3 years ago

Answer:

F(x)=2x^2

Step-by-step explanation:

Basically, a quadratic function has x^2 in it (standard form ax^2+bx+c with non-zero a). The others have x^3, -x, x^4, etc., which clearly are NOT x^2.

You have purchased a mobile home for $20,000 which depreciates at 10% per year.
iragen [17]

Answer:

  C.  Three

Step-by-step explanation:

We want to solve the equation for n:

  14,580 = 20,000(9/10)^n

  14580/20000 = 729/1000 = (9/10)^n

  (9/10)^3 = (9/10)^n . . . . . . write the left side as a cube

  3 = n . . . . . . equate exponents

After year 3, the value will be $14,580.

_____

You can use logarithms to find n:

  log(0.729) = n×log(0.9) . . . . . . taking the log of the 2nd line above

  log(0.729)/log(0.9) = n = 3

Where in real life we come across something that is more than 100 %example 135 give 3 examples<br>​
dangina [55]

Real life scenarios where percentage exceeds 100% include :

  • Profit change
  • Inflation
  • Population growth

100% is used to represent the total percentage of a whole. Such that the highest percentage value of a whole such as the number of people who reside in a country, the mark obtainable in a examination and so on.

The mark obtainable in an examination cannot exceed 100%

However, there are circumstances whereby percentage values are represented as more than 100%.

These scenarios usually involves instances where values are compared and expressed as percentages.

Comparing the change in price of goods between two periods :

A good that cost $20 in 2005 which is now being sold at $50. The percentage change in price in this scenario will be :

[($50 - $20) / $20] × 100% = (30/20 × 100%) = 150%

Similary ;

In Finance, profit comparison usually involves using percentages greater than 100%.

For instance ;

if a firm makes double it previous year's profit, the would be said to have made an 100% increase from previous year's profit.

If the profit is 3 times, then that would mean a 200% profit increase.

For example :

Previous year's profit = $50,000

This year's profit = $150,000

Percentage profit increase :

[($150,000 - $50,000) / $50,000] × 100%

($100,000 / $50000) × 100%

2 × 100% = 200%
