Using a^2+b^2=c^2 it would be a^2+12^2=14^2

a^2+144=196
a^2=340
then square rooted would be a=18.439

The equation V = 16300 (0.94)^t represents the value (in dollars) of a car t years after its purchase. Use this equation to comp

Dafna1 [17]

Solution:

Given:

$V=16300(0.94)^t$

The value of a car after t - years will depreciate.

Hence, the equation given represents the value after depreciation over t-years.

To get the rate, we compare the equation with the depreciation formula.

$\begin{gathered} A=P(1-r)^t \\ \text{where;} \\ P\text{ is the original value} \\ r\text{ is the rate} \\ t\text{ is the time } \end{gathered}$

Hence,

$\begin{gathered} V=16300(0.94)^t \\ A=P(1-r)^t \\ \\ \text{Comparing both equations,} \\ P=16300 \\ 1-r=0.94 \\ 1-0.94=r \\ r=0.06 \\ To\text{ percentage,} \\ r=0.06\times100=6\text{ \%} \\ \\ \text{Hence, } \\ P\text{ is the purchase price} \\ r\text{ is the rate} \end{gathered}$

Therefore, the value of this car is decreasing at a rate of 6%. The purchase price of the car was $16,300.

Mell is twice as old as Jerry. If 16 is subtracted from Mell’s age and 16 is added to Jerry’s age, their ages will be equal. Wha

irga5000 [103]

Answer:

Step-by-step explanation:

Let J = Jerry's age

Let M = Mary's age = 2J

M - 16 = J + 16

Substitute 2J for Mary's age

2J - 16 = J + 16

2J - J - 16 = 16

J = 16 + 16

J = 32

Jerry is 32.

Mary is twice as old as Jerry.

Mary is 2(32) = 64
