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

During taylor's experiment, which piece of data would be qualitative?
Reptile [31]

There isn't any piece of data during Taylor's experiment which can be taken as  qualitative. Thus, correct choice is: Option D: None are qualitative.

<h3>What is qualitative data?</h3>

Qualitative data tells about the quality or characteristic. It is tough to express it numerically or not at all expressible numerically. They are usually catagorical.

In contrast, there is quantitative data which can be expressed numerically.

The problem is missing its option, which are:

  1. mass of the cars
  2. degree of the ramp incline
  3. time in seconds
  4. none are qualitative

Mass can be measured (in kgs, grams etc), degree of inclination can be measured (in radians, degree etc), time can be measured (in seconds, minutes etc).

Thus, there isn't any piece of data during Taylor's experiment which can be taken as  qualitative. Thus, correct choice is: Option D: None are qualitative.
