The general equation for depreciation is given by y = A(1 – r)t, where y = current value, A = original cost, r = rate of depreci
irina1246 [14]
Analyzing the given values and the given equation, we have the following:
A = $25,000
r = 0.11
t = 6

The equation has the form:
y = A (1-r)^t
Plugging in the given values into the equation,
y = $25,000 (1 - 0.11)^6
y = $25,000 (0.89)^6

Therefore, the answer is
A. y=25,000(.89)^6

The function f(x) = 2x2 + 3x + 5, when evaluated, gives a value of 19. What is the function’s input value?
goldenfox [79]
f(x)=\quad 2{ x }^{ 2 }+3x+5

Let's called the input 'z'

When we plug 'z' in the function we get ;

f(z)=\quad 2{ z }^{ 2 }+3z+5

And we know that, this is equal to 19, so ;

2{ z }^{ 2 }+3z+5=\quad 19

Let's rearrange the equation.

2{ z }^{ 2 }+3z+5=\quad 19\\ \\ 2{ z }^{ 2 }+3z=\quad 19-5\\ \\ 2{ z }^{ 2 }+3z=\quad 14\\ \\ 2{ z }^{ 2 }+3z-14=\quad 0

So we have a quadratic equation here.

We'll use this formula to solve it :

\frac { -b\pm \sqrt { { b }^{ 2 }-4ac }  }{ 2a }

The formula is used in equation formed like this :

a{ x }^{ 2 }+bx+c=0

In our equation,

a=2 , b=3 and c=-14

Let's plug in the values in the formula to solve,

a=2\quad b=3\quad c=-14\\ \\ \frac { -3\pm \sqrt { 9-(4\cdot 2\cdot -14) }  }{ 4 } \\ \\ \frac { -3\pm \sqrt { 9-(-112) }  }{ 4 } \\ \\ \frac { -3\pm \sqrt { 9+112 }  }{ 4 } \\ \\ \frac { -3\pm \sqrt { 121 }  }{ 4 } \\ \\ \frac { -3\pm 11 }{ 4 }

So,

z=\quad \frac { -3+11 }{ 4 } \quad ,\quad \frac { -3-11 }{ 4 } \\ \\ z=\quad \frac { 8 }{ 4 } \quad ,\quad \frac { -14 }{ 4 } \\ \\ z=\quad 2,\quad -\frac { 7 }{ 2 }

So the input can be both, 2 and -\frac{7}{2}
