Step-by-step explanation:

Data:

The function is expressed as:

(f·g) (1)

This means that the function is defined as:

function of f(x) function of g(x) when x is 1. By evaluation, the graphs for each function are drawn. The point of intersection is the solution to the expression:

(f·g)(1)

Ralph Chase plans to sell a piece of property for $160,000. He wants the money to be paid off in two ways monica short-term no

DerKrebs [107]

Answer:

short-term: $90,000
long-term: $70,000

Step-by-step explanation:

Let x represent the amount borrowed on the short term. Then 160000-x is the amount of the long-term note. The total interest is ...

0.11x +0.08(160000-x) = 15500

0.03x + 12800 = 15500 . . . . simplify

0.03x = 2700 . . . . . . . . . subtract 12800

x = 2700/.03 = 90,000 . . . . short-term note

160,000 -90,000 = 70,000 . . . . long-term note

The short-term note was for $90,000; the long-term note was for $70,000.

Identify the zeros of the function f(x) = 2x^2 − 4x + 5 using the Quadratic Formula

Nostrana [21]

For this case we have that by definition, the roots, or also called zeros, of the quadratic function are those values of x for which the expression is 0.

Then, we must find the roots of:

$2x ^ 2-4x + 5 = 0$

Where:

$a = 2\\b = -4\\c = 5$

We have to: $x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}$

Substituting we have:

$x = \frac {- (- 4) \pm \sqrt {(- 4) ^ 2-4 (2) (5)}} {2 (2)}\\x = \frac {4 \pm \sqrt {16-40}} {4}\\x = \frac {4 \pm \sqrt {-24}} {4}$

By definition we have to:

$i ^ 2 = -1$

So:

$x = \frac {4 \pm \sqrt {24i ^ 2}} {4}\\x = \frac {4 \pm i \sqrt {24}} {4}\\x = \frac {4 \pm i \sqrt {2 ^ 2 * 6}} {4}\\x = \frac {4 \pm 2i \sqrt {6}} {4}\\x = \frac {2 \pm i \sqrt {6}} {2}$
