<h3>Answer: D. All real numbers greater than 0</h3>

In terms of symbols, we would write $x > 0$

The natural log function, or any log function, is not defined for x = 0 or any negative x value.

Consider the form $\log_b(y) = x$ which is equivalent to $y = b^x$ and notice how the y value slowly approaches zero but never actually gets there. That is one way to see why the inputs of any log function must be larger than 0.

If ED = x + 4 and DB = 3x - 8, find ED, DB, and EB

Tom [10]

Answer:

Part 1) $ED=10\ units$

Part 2) $DB=10\ units$

Part 3) $EB=20\ units$

Step-by-step explanation:

we know that

EB=ED+DB

ED=DB -----> given problem

Substitute the given values and solve for x

$x+4=3x-8$

$3x-x=4+8$

$2x=12$

$x=6$

<em>Find the value of ED</em>

$ED=x+4$

substitute the value of x

$ED=6+4=10\ units$

<em>Find the value of DB</em>

Remember that

ED=DB

therefore

$DB=10\ units$

<em>Find the value of EB</em>

EB=ED+DB

$EB=10+10=20\ units$

--------------------------------------------
`   right angle   |_ |
` (right triangle ) |
   `    | 4
`       |
`
"c" ` \
(hypotenuse)     Starting point

__________________________________________________
Since we have a "right triangle, we solve for "c"; using the
"Pythagorean theorem" ;
_______________________________________________________
→ a² + b² = c² ; Solve for "c" ; our answer (in "miles"; or, "mi.") ;
__________________________________________________
Given : a = 4; b = 5 ;
____________________________
Plug these known values into our equation:
________________________________________
→ 4² + 5² = c² ;
____________________________
→ 16 + 25 = c² ; ↔ c² = 16 + 25 ;
______________________________
→ c² = 41 ;
_______________________________
→ Take the positive square root of each side of the equation (since the side of a "triangle" cannot be "negative";
__________________________________
→ √(c²) = √(41) ;
_____________________________
→ c = √41 ; Use calculator;
________________________________
→ c = 6.40312423743 ; Round to:

→ c = 6.403 miles; or, 6.403 mi.
