kaleigh owns an appliance store. she purchases a new refrigerator to use in her store. the refrigerator depreciates by a fixed rate per year. the function v = 2,600(0.74)t can be used to model the value of the refrigerator after t years.

part a: explain what the parameter 2,600 represents in the equation of the function.

part b: by what percentage does the value of the refrigerator increase or decrease each year? explain your answer.

part c: what is the value of the refrigerator after 3 years rounded to the nearest dollar? you must show your work.

Part A

2600 is the initial price of the refrigerator. That would be the purchase price.

Part B

b = .74  This is how much value is keeps each year.  It is decaying by 1-.74 = .26  or 26 % decrease each year

Part C

1054.00

Step-by-step explanation:

V = 2,600(0.74)^t

This is in the form y =ab^x

where a is the initial value, b is the growth (or decay) rate , and x is the time

Part A

2600 is the initial price of the refrigerator. That would be the purchase price.

Part B

b = .74  This is how much value is keeps each year.  It is decaying by 1-.74 = .26  or 26 % decrease each year

Part C

V = 2,600(0.74)^t

Let t =3

V = 2,600(0.74)^3

   =2600 (.405224)

  =1053.5824

To the nearest dollar

  1054.00

step-by-step explanation:

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
