The value of x from the expression is $\frac{ln8-8}{3}$

Given the exponential function $e^{3x+8}=8$

Take the natural logarithm of both sides:

$lne^{3x+8}=ln8\\3x +8=ln8$

Subtract 8 from both sides:

$3x-8+8=ln8-8\\3x=ln8-8$

Divide both sides by 3:

$\frac{3x}{3} =\frac{ln8-8}{3}\\x= \frac{ln8-8}{3}$

Hence the value of x from the expression is $\frac{ln8-8}{3}$

A merchant buys a television for $125 and sells it for $75 more. what is the percent of markup?

guajiro [1.7K]

Since he sold it for $75 more,

% Mark Up = Mark Up/ Cost Price * 100%

% Mark Up = 75 / 125 * 100%

= 0.6 * 100% = 60%

Percent Mark Up = 60%.

Hope this explains it.

e) Given the following: Let X = {1, 2, 3, 4) and a relation R on X as R= {(1,2), (2,3), (3,4)}. Find the reflexive and transitiv

Naddika [18.5K]

Answer:

The answer is $\{(1,1),(2,2),(3,3),(4,4),(1,2)(2,3)(3,4),(1,3),(1,4)\}$

Step-by-step explanation:

Remember that a reflexive relation $R\subset \mathcal{P}(X)$ , where $\mathcal{P}(X)$ is the power set of $X$ , is one which conteins the ordered pairs of the form $(a,a)$ , for $a\in X$ .

So, As the reflexive and transitive closure of $R$ (that we will denote by $\overline{R}$ ) is in particular reflexive, we must add to $R$ the elements $\{(1,1) , (2,2),(3,3),(4,4) \}$

A transitive relation $R$ is one in which if the pair $(a,b)$ and the pair $(b,c)$ are in there, then the pair $(a,c)$ must be there too.

So, to complete the relation $R$ to be reflexive and transitive we must add the pair $(1,3)$ (because $(1,2),(2,3)$ are in $R$ ), the pair $(2,4)$ , and the pair $(1,4)$ because we added the pair $(2,4)$ .
