Sharon purchased a used car for $24,600. The car depreciates exponentially by 8% per

Tju [1.3M]

Answer:

The value of car after 5 years of exponentially depreciation is $16,213.36

Step-by-step explanation:

The initial amount of the car = i = $24,600

The depreciates rate of interest applied = r = 8%

Let The value of car after n years = A

The number of years = n = 5 years

Now,According to question

The value of car after n years = initial price of car × $(1-\dfrac{\textrm rate}{100})^{\textrm time}$

Or, The value of car after 5 years = i × $(1-\dfrac{\textrm r}{100})^{\textrm n}$

Or, $A = $24,600 × $(1-\dfrac{\textrm 8}{100})^{\textrm 5}$

Or, $A = $24,600 × $(0.92)^{5}$

Or, $A = $24,600 × 0.65908

Or, $A = $16,213.36

So, The value of car after 5 years = A = $16,213.36

Hence , The value of car after 5 years of exponentially depreciation is $16,213.36 . Answer

How do you find the complete square of a math problem

dolphi86 [110]

Step-by-step explanation:

I am not sure what exactly you mean.

do you mean the complete square of an expression or

term ?

if so, then by multiplying this term by itself, and that means in general, every part is multiplied by every part and the part results are added considering the signs involved.

e.g.

squaring a+b

(a+b)(a+b) = a×a + a×b + b×a + b×b = a² + 2ab + b²

remember that multiplication and addition are commutative (you can flip the right and left sides with each other and still get the same result : a+b = b+a, a×b = b×a).

squaring a-b

(a-b)(a-b) = a×a + a×-b + -b×a + -b×-b = a² - 2ab + b²

remember that

+×- = -×+ = -

-×- = +

+×+ = +

a more complex example ?

squaring a-b+c

(a-b+c)(a-b+c) =

= a×a + a×-b + a×c + -b×a + -b×-b + -b×c + c×a + c×-b + c×c =

= a² - 2ab - 2bc + 2ac + b² + c²
