Answer:
3.27 meters
Step-by-step explanation:
The given equation gives a y(0) = 0, for the deflection of 3 cm. Then for a deflection of 2.5 cm, we want y(x) = 0.005, half a centimeter above the low point on the beam. Using this value, we can solve for x:
0.005 = 3/6400x^2
32/3 = x^2
4√(2/3) = x ≈ 3.26599 ≈ 3.27 . . . . meters
The deflection of the beam is 2.5 cm at a distance of 3.27 meters from center.

Explanation:

Given: " ln (3x + 5) = ln (2x <span>− 2) " ; Solve for "x" .
_________________________________________________________
Remove the "ln" on both sides of the equation:
We have:
" 3x + 5 = 2x </span><span>− 2 " ;
Add "2" to each side of the equation; & subtract "2x" from each side of the equation:
3x + 5 + 2 </span>− 2x = 2x − 2 + 2 <span>− 2x ;
to get:
x + 7 = 0 ;
Now, subtract "7" from each side of the equation;
to isolate "x" on one side of the equation; & to solve for "x" ;
x + 7 </span>− 7 = 0 <span>− 7 ;
to get:
_________________________________________________________
</span> x = - 7 .
_________________________________________________________
The answer is: " x = - 7 " .
