The dollar value v(t) of a certain car model that is t years old is given by the following exponential function. v(t)=29,900(0.7

olga2289 [7]

Answer:

(a)Initial Value: $29,900

(b)Value after 12 years: $1516.37

Explanation:

Given the dollar value v(t) of a certain car model that is t years old as:

$v\mleft(t\mright)=29,900\mleft(0.78\mright)^t$

(a)Initial Value

At initial value, that is, when the car was just purchased, t=0

$\begin{gathered} v\mleft(t\mright)=29,900\mleft(0.78\mright)^t \\ \implies v\mleft(0\mright)=29,900\mleft(0.78\mright)^0=29,900\times1=29,900 \end{gathered}$

The initial value of the car is $29,900.

(b)The value after 12 years.

When t=12

$\begin{gathered} v\mleft(t\mright)=29,900\mleft(0.78\mright)^t \\ \implies v\mleft(12\mright)=29,900\mleft(0.78\mright)^{12}=\$1516.37 \end{gathered}$

The value of the car after 12 years is $1516.37.

Which expression is equivalent to -7- (-2.5)?

Ket [755]

Answer: none
-7-(-2.5) in the calculator is -4.5
Which would mean none were equivalent, but if i do it by hand then the answer would be -17.5; again none would be equivalent.
But the closest one is -2.5-7, because it equals 4.5 rather than -4.5
