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

we do ×/÷ first from the left
so 4.44+ 0.8571428571 = 5.301

I need help please?!!!

Y-axis, because what i’ve been taught with coordinates, is you crawl before you walk which means is first it’s x-axis then y-axis. so (0,4) would be on the y-axis. :)
