The value of a car after t years can be found using the formula V = C(1 - r)t, where V is the current value of the car, C is the
Stells [14]
The given formula is
V = C(1-r)^{t}

Therefore
(1-r)^{t} =  \frac{V}{C} \\\\ 1-r = ( \frac{V}{C} )^{1/t} \\\\ r = 1 - ( \frac{V}{C} )^{1/t}

Given:
C = $25,000
V = $12,000
t = 4.5 years

C/V = 0.48
1/t = 0.2222
Therefore
r = 1 - 0.48^{0.2222} = 0.1505 = 15.05\%

Answer: 15% (nearest integer)

Which expression is a difference of squares with a factor of 5x − 8? 25x2 − 16 25x2 16 25x2 − 64 25x2 64.
SpyIntel [72]

The product of the factors (5x − 8) and (5x + 8) is 25x² −  64. Then the correct option is C.

<h3>What is polynomial?</h3>

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

One factor of the polynomial is given which is 5x − 8.

Then the polynomial will be

Let the other factor be 5x + 8

Then their product will be

(5x − 8)(5x + 8)

(5x)² − 8²

25x² −  64

More about the polynomial link is given below.
