A car, originally valued at 70,000 in 2006 depreciates exponentially at a rate of 4% each year. Round the expected value of the
lora16 [44]

Answer:

$42,890

Step-by-step explanation:

The standard form for an exponential equation is

y=a(b)^x

where a is the initial amount value and b is the growth rate or decay rate and t is the time in years.  Since we are dealing with money amounts AND this is a decay problem, we can rewrite accordingly:

A(t)=a(1-r)^t

where A(t) is the amount after the depreciation occurs, r is the interest rate in decimal form, and t is the time in years.  We know the initial amount (70,000) and the interest rate (.04), but we need to figure out what t is.  If the car was bought in 2006 and we want its value in 2018, a total o 12 years has gone by.  Therefore, our equation becomes:

A(t)=70,000(1-.04)^{12} or, after some simplification:

A(t)=70,000(.96)^{12}

First rais .96 to the 12th power to get

A(t) = 70,000(.6127097573)

and then multiply.

A(t) = $42,890

Show how to simplify y-8 = 3/4x [x-(-6)]
notsponge [240]

To simplify the equation, we have y = \frac{3}{4x^2 + 24x} + 8

<h3>How to simply the expression</h3>

Given the expression

y-8 = 3/4x [x-(-6)]

First, expand the bracket

y - 8= \frac{3}{4x^2 + 24x}

Make 'y' the subject of formula

y = \frac{3}{4x^2 + 24x} + 8

Thus, to simplify the equation, we have y = \frac{3}{4x^2 + 24x} + 8
