Last month, Maria purchased a new cell phone for $500. The store manager told her that her new cell phone would depreciate by 70% every 6 months. Maria thinks she will want to replace her phone after a while. What will be the value (V) of her phone if she tries to trade it in after 2 years? Select all that apply.

or

Step-by-step explanation:

The value of her phone after t intervals of 6 months is given by the following equation:

In which V(0) is the initial value and r is the depreciation rate, as a decimal.

Last month, Maria purchased a new cell phone for $500.

This means that

The store manager told her that her new cell phone would depreciate by 70% every 6 months.

This means that

So

After 2 years:

2 years is 24 months, 24/6 = 4, so we have to find V(4).

The possible options are:

or

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
