It can be deduced that the set of fractions that is an example of reciprocal fractions include, 1/2 , 3/1, and 1/6.

<h3>What is a reciprocal fraction?</h3>

It should be noted that a reciprocal fraction simply means the number whose product with the given fraction is 1.

Here, the set of fractions that is an example of reciprocal fractions include, 1/2 , 3/1, and 1/6. This is because their product isn't equal to 1.

Solve the equation using the quadratic formula. Enter each solution in simplest form.

sergeinik [125]

For this case we have the following quadratic equation:

$x ^ 2-4x + 23 = 0$

The solutions will be given by:

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

Where:

$a = 1\\b = -4\\c = 23$

Substituting the values we have:

$x = \frac {- (- 4) \pm \sqrt {(- 4) ^ 2-4 (1) (23)}} {2 (1)}\\x = \frac {4 \pm \sqrt {16-92}} {2}\\x = \frac {4 \pm \sqrt {-76}} {2}\\x = \frac {4 \pm \sqrt {76i ^ 2}} {2}\\x = \frac {4 \pmi \sqrt {76}} {2}\\x = \frac {4 \pmi \sqrt {2 ^ 2 * 19}} {2}\\x = \frac {4 \pm2i \sqrt {19}} {2}\\x = 2 \pm i\sqrt {19}$

We have two roots:

$x_ {1} = 2-i \sqrt {19}\\x_ {2} = 2 + i \sqrt {19}$

ANswer:

$x_ {1} = 2-i\sqrt {19}\\x_ {2} = 2 + i\sqrt {19}$

All log graphs contain the points (1,0), (a,1), and (1/a,-1).<br><br> True .<br> False.

Bumek [7]

The correct answer is: True

Explanation:
1. $log_a1 = 0$ (Straightforward)
2. $log_aa = 1
$ (log to base of itself is always 1)
3. $log_a \frac{1}{a} = log_aa^{-1} = -1(1) = -1$ (Using log power property)

Hence the correct option is True.

What is the slope of the line perpendicular to the y=-1/5x-9? <br><br> Plz help me

labwork [276]

Answer:

Step-by-step explanation:

Remember that the slope of a line that is perpendicular to a given line is the negative reciprocal of the slope of the given line.

Here we are given the line y = -(1/5)x - 9. The slope is (-1/5). The negative reciprocal of this is +5. That's the answer you wanted.

Find the domain in interval notation.

Nady [450]

Answer:

Step-by-step explanation:

x³ - 64x = x( x² - 64 ) ≠ 0 ⇒ x ≠ 0 and x ≠ ± 8

<em>x ∈ ( - ∞ , - 8 ) ∪ ( - 8 , 0 ) ∪ ( 0 , 8 ) ∪ ( 8 , ∞ )</em>
