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

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
