Find the midpoint of the line segment with the given endpoints.<br> 1) (-8, 3), (-8,-4)

defon

Answer:

The answer is

<h2> $( - 8 \: , \: - \frac{1}{2} )$ </h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

$M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} ) \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-8, 3), (-8,-4)

The midpoint is

$M = ( \frac{ - 8 - 8}{2} \: , \: \frac{3 - 4}{2} ) \\ = ( - \frac{16}{2} \: , \: - \frac{1}{2} )$

We have the final answer as

$( - 8 \: , \: - \frac{1}{2} )$

Hope this helps you

Answer:

9

Step-by-step explanation:

you want the trinomial (x*x - 6x + __ ) to be written as a binomial squared.

So we would need to realize that the constant would be equal to (-6/2)^2 =(-3)^2 = 9

We have completed the square.

f(x) = 4*( x - 3)^2 + 20 is now in Vertex Form

F(x) = ^3 Squared 3x g(x) = 32 + 2 Find (f/g) (x)

Lunna [17]

By applying the <em>functional</em> theory related to <em>binary</em> operations of functions, we conclude that the resulting expression is equal to $(f \,\circ \,g) (x) = \frac{\sqrt[3]{3\cdot x} }{3\cdot x + 2}$ .

<h3>How to find the expression of a division between two functions</h3>

In <em>functional</em> theory, there are five operations that can be used between two functions:

Addition - (f + g) (x) = f(x) + g(x)
Subtraction - (f - g) (x) = f(x) - g(x)
Multiplication - (f · g) (x) = f(x) · g(x)
Division - (f/g) (x) = f(x) / g(x)
Composition - (f ο g) (x) = f (g (x))

In this question we are asked to derive the expression of the division between two functions given. If we know that $f(x) = \sqrt[3]{3\cdot x}$ and g(x) = 3 · x + 2:

$(f \,\circ \,g) (x) = \frac{\sqrt[3]{3\cdot x} }{3\cdot x + 2}$

By applying the <em>functional</em> theory related to <em>binary</em> operations of functions, we conclude that the resulting expression is equal to $(f \,\circ \,g) (x) = \frac{\sqrt[3]{3\cdot x} }{3\cdot x + 2}$ .

<h3>Remark</h3>

The statement is poorly formatted and reports many typing mistakes. Correct statement is shown below:

Let $f(x) = \sqrt[3]{3\cdot x}$ and g(x) = 3 · x + 2. Find (f/g) (x).
