The annual rate of depreciation, x, on a car that was purchased for $9,000 and is worth $4,500 after 5 years can be found using

Zolol [24]

Answer:

Step-by-step explanation:

We know that exponential formula of depreciation

$A=P(1-x)^t$

where

P is the initial amount

x is the interest rate

A is the amount after t years

we are given

The annual rate of depreciation, x, on a car that was purchased for $9,000

so, P=9000

we can plug value it

$A=9000(1-x)^t$

we are given

when x=5 , A=4500

so, we can plug it and solve for x

$4500=9000(1-x)^5$

$\frac{9000\left(1-x\right)^5}{9000}=\frac{4500}{9000}$

$\left(1-x\right)^5=\frac{1}{2}$

$x=-\left(\frac{1}{2}\right)^{\frac{1}{5}}+1$

$x=0.12945$

so, interest rate is 13%

now, we can plug x

and we get

$A=9000(1-0.13)^t$

$A=9000(87)^t$

A rectangular parking lot has a perimeter of 384 meters. The length of the parking lot is 36 meters less than the width. Find th

-Dominant- [34]

Answer:

The length and width of the parking lot is 78 meters and 114 meters respectively.

Step-by-step explanation:

Given;

Perimeter of the parking lot = $384\ m$

Solution,

Let the width of the parking lot be x.

Then, according to question length = (x-36).

The perimeter of a rectangle is sum of all the sides of rectangle. Which is given by an expression;

$perimeter=2\times(length+width)$

Now substituting the values, we get;

$384=2\times(x-36+x)\\\frac{384}{2}=(2x-36)\\192=2x-36\\192+36=2x\\2x=228\\x=\frac{228}{2}= 114$

Width = $114\ m$

Length = $x-36=114-36=78\ m$

Hence the length and width of the parking lot is 78 meters and 114 meters respectively.
