Answer:

Step-by-step explanation:

If the value of the TV decreases by 14% each year, then the rate is exponential.

We would apply the formula for exponential growth which is expressed as

A = P(1 + r/n)^ nt

Where

A represents the price of the TV after t years.

n represents the periodic rate at which the decrease is calculated.

t represents the number of years.

P represents the initial price of the TV.

r represents rate of decrease in value of the TV.

From the information given,

P = $1500

r = 14% = 14/100 = 0.14

n = 1

A = y

Therefore, the function would be

y = 1500(1 + 0.14/1)^ 1 × t

y = 1500(1.14)^t

Answer:

value of the tv = $1500

Decrease rate per year = 14%

14% of $1500 = (14 x 1500)/100

14% of $1500 = 21000/100

14% of $1500 = 210

In first year depreciation  would be y - 210(t) = 1500 -210(1) = 1290

The function to calculate y after t years would be : y - 210(t)

                                                                       

The function would be y - 210(t)

Andru [333]


Area = length * width

width = w

length = 2w+7

A = (2w+7) * w

250 =2w^2+7w

The problem
Afina-wow [57]

Answer:

Step-by-step explanation:

In the given division, when 24.725 is divided by 215,

Step 1 is the wrong step.

Quotient in first step will be 0.1 .

Part C.

215) 24.725 (0.115

      <u> 215</u>

          322

          <u>215</u>

           1075    

           <u>1075</u>

                0

Therefore, the correct way to divide should be as agove.

Quotient after division should be 0.115.
