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

const2013 [10]

Answer:

x=20

Step-by-step explanation:

log3(4x+1) = 4

Raise each side to the base of 3

3^log3(4x+1) = 3^4

4x+1 = 3^4

4x+1 = 81

Subtract 1 from each side

4x+1-1 = 81-1

4x= 80

Divide by 4

4x/4 = 80/4

x = 20
