Answer:

The value of the car after 3 years is R$58.320.

O valor do carro ao final desse período é R$58.320.

Step-by-step explanation:

The value of the car after t years is given by the following equation:

V(t) = V(0)(1-r)^{t}

In which V(0) is the initial value and r is the yearly depreciation rate.

In this question, we have that:

V(0) = 80000, r = 0.1

So

V(t) = V(0)(1-r)^{t}

V(t) = 80000(1-0.1)^{t}

V(t) = 80000(0.9)^{t}

Value of the car at the end of 3 years:

V(3) = 80000(0.9)^{3} = 58320

The value of the car after 3 years is R$58.320.

O valor do carro ao final desse período é R$58.320.

What is the equation of the following line? Be sure to scroll down first to see all answer options.
Serjik [45]

Answer:

<h3>The answer is option F</h3>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To calculate the equation of the line first find the slope

Slope of the line using points

(0 , 0) and (4 , -2) is

m =  \frac{ - 2 - 0}{4 - 0}  =  \frac{ - 2}{4}  =  -  \frac{1}{2}

Now use the formula

y - y1 = m(x - x1) to find the equation of the line using any of the points

Using point (0,0)

That's

y - 0 =   - \frac{ 1}{2} (x - 0)

The final answer is

y =  -  \frac{1}{2} x

Hope this helps you

PilotLPTM [1.2K]

Answer:4 dozens of video games would cost $1956

Step-by-step explanation:

An electronic store prices 3 dozen video games at a total of 1467. A dozen of video games is 12. Therefore, the total number of video games whose cost is 1467 is 12 × 3 = 36

if each video game costs the same amount, then the cost of one video game would be

1467/36 = $40.75

The total number of video games in 4 dozens of video game would be

4 × 12 = 48

Therefore, the total cost of 48 video games would be

48 × 40.75 = $1956
