the current value of a new car is 18,000. the car will depreciate 15% per year over the next 5 year. which exponential equation
Arte-miy333 [17]

The exponential equation that models this situation is:

V(t) = 18000(0.85)^t, 0 \leq t \leq 5.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

For this problem, the parameters are:

A(0) = 18000, r = 0.15.

Hence the equation for the value of the car over the next 5 years is:

A(t) = A(0)(1 - r)^t

A(t) = 18000(1 - 0.15)^t

V(t) = 18000(0.85)^t, 0 \leq t \leq 5.

3 ⅕ -⅔ divided by 2 ⅘
spin [16.1K]

Answer:

160/196

Step-by-step explanation:

it would be easier if you converted all fractions to improper fractions

so 3 1/5 would equal 16/5 and 2 4/5 would equal to 14/5

\frac{14}{5} - \frac{2}{3} : to solve this you would need the same common denomenator,

to do this you can multiply 5 and 3 by something to make the lowest common denominator, which would be 15

thus

multiplying first fraction by 3 and the second by 5

42/15 - 10/15 = 32/15

now 32/15 divided by 14/5

the rule for dividing fractions, is flipping the fraction which you will be using to divide, and then multiplying it to the first fraction:

\frac{32}{14} multiplied by \frac{5}{14}

thus, answer is 160/196

Simplify -78 ÷ (-9)<br><br><br><br> (Write answer as a mixed number: whole and fraction remaining.)
juin [17]

Answer:

8 2/3

<em>Y-E-E-T</em>

Step-by-step explanation:

-78 divded by (-9)

-78

-----

-9

there are negatives on both sides. I don't know how to explain that but you can change it to a PLUS.

78/9

divide 3 on both sides

78/3 =26

9/3=3

26/3 now.

so the mixed number would be 8 2/3
