What is the equation of the exponential function??

Mathematics
1 answer:
Alex787 [66]3 years ago
8 0

Answer:

  • $19500

Step-by-step explanation:

<u>Let the depreciation rate is x per year, then we have:</u>

  • 28000*x² = 22000
  • x² = 22000/28000
  • x² = 0.7857
  • x = √0.7857
  • x = 0.8864

<u>Exponential function for this case is:</u>

  • V(t) = 28000*0.8864^t, where V(t) - future value, t- number of years

<u>Value of the car after 3 years:</u>

  • V(3) = 28000*0.8864^3
  • V(3) = 19500

2. A palindrome is a number or a word that is the same in the two directions: left to right and vice
a_sh-v [17]

Answer:

90 between 1000 and 9999

Step-by-step explanation:

The first digit cannot be 0. It can be nine other digits.

The second digit can be anything between 0 and 9.

To be palindromic the 2nd and 3rd digits must be the same.

And in addition, the 1st and 4 numbers must be the same.

So the answer is 9 * 10 = 90. That does seem too small, but try making a palindrome with the restrictions I have outlined. None of the examples you have given beginning with 8 are palindromic.

8118 is palindromic

8998 is also palindromic

9009 is palindromic

2002 is palindromic

There are only 90 of them.
