Suppose that a company has just purchased a new computer for $1500 The company chooses to depreciate using the straight-line met
agasfer [191]

<u>Solution-</u>

The company purchased a new computer for $1500 and chooses to depreciate using the straight-line method for 5 years.

a-

As the value is depreciating, so its slope will be -ve.

Slope =- \frac{1500}{5}=-300 ( ∵ The value of 1500 will depreciate in 5 years )

y-intercept = 1500           ( ∵ At the beginning when x=0, y=1500)

Linear equation of the system,

y = mx +c ,

where,

m = slope = -300,

c = y-intercept = 1500

Putting the values,

y=-300x+1500

\Rightarrow y=1500-300x


b-

The implied domain of the function is 1≤x≤5 or [1,5]


c-

Follow the attachment attached herewith for the graph.


d-

Here,

y = the value of the computer

.

x = number of years depreciated = 3

Putting the values in the linear equation,

y = 1500-300(3) = 1500-900 = 600

∴  The book value of the computer after 3 years is $600.


e-

Here given that,

y = value of computer = 1600

x = asked = ??

Putting the values in the equation,

1600 = 1500 - 300x

⇒ 100= -300x

⇒ x= -3

∴ As the x is in negative, i.e it is impossible for the computer to be worth of 1600. It happens also because as the value is depreciating, it will always be less than 1500.

When using the quadratic formula we call the part under that radical the discriminant this part of the formula can be used to he
blondinia [14]

Answer:

A, B, and C

Step-by-step explanation:

The discriminant is denoted by b^2 - 4ac, and it can give us information about the roots of the quadratic equation.

It tells us that if:

- b^2 - 4ac < 0 , then there are 0 real solutions; they're all imaginary (involving the letter i, which is the square root of -1)

- b^2 - 4ac = 0 , then there is 1 real solution; this 1 solution has a multiplicity of 2 because the roots of the quadratic are the same number

- b^2 - 4ac > 0 , then there are 2 real solutions; there are no imaginary solutions

Looking at the possible choices, we see that all of A (A, I'm assuming you meant to write "if the discriminant is zero there is one real solution"), B, and C reflect the above properties.

Thus, they're all right.

Suppose that the halflife of a substance is 250 years . If there were ir 100 the substance , (a) give an exponential model for t
IgorLugansk [536]
After 500 years one would have N nuclei of the original substance.

N = 100 * exp ( -ln(4) ) = 25

LOL.

I guess it is exp( - lamda * t)

Lamda, the decay constant is the ln(2) over the half life.

So we get exp( -ln(2)/250 * 500) or exp ( -ln(4) )
