National Textile installed a new textile machine in one of its factories at a cost of $250,000. The machine is depreciated linea

kirill115 [55]

Answer:

The required expression is $y=250,000-24,000 t$

Step-by-step explanation:

Consider the provided information.

National Textile installed a new textile machine in one of its factories at a cost of $250,000.

That means for 0 year the cost of the machine is $250,000.

This can be written as: (0, 250,000)

Over 10 years with a scrap value of $10,000

That means for 10 year the cost of the machine is $10,000.

This can be written as: (10, 10,000)

Now first find the rate of change:

Rate of change=m= $\frac{Rise}{Run}=\frac{10,000-250,000}{10-0}$

Rate of change=m= $\frac{Rise}{Run}=\frac{-240,000}{10}$

Rate of change=m= $\frac{Rise}{Run}=-24,000$

Now use the point-slope form of an equation of a line with the point (0, 250,000), we can find the required expression.

$(y-250,000)=-24,000(t-0)$

$y-250,000=-24,000 t$

$y=250,000-24,000 t$

Hence, the required expression is $y=250,000-24,000 t$

Which is the correct form of the quadratic formula? A) x = b ± b2 - 4ac a B) x = b ± b2 - 4ac 2a C) x = - b ± b2 - 4ac a D) x =

DochEvi [55]

That's pretty ill-formatted but the answer is D

$ax^2 + bx + c = 0$

has roots given by

$x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

Bonus quadratic formulas:

The Shakespeare Quadratic Formulas ( $2b$ or $-2b$ ) are:

$x^2 - 2bx + c \textrm{ has zeros at }x=b \pm \sqrt{b^2-c}$

$ax^2 - 2bx + c \textrm{ has zeros at }x=\frac 1 a( b \pm \sqrt{b^2-ac})$
