Answer: x = 1.1968729357 ; or, round to: 1.2 .
____________________________________________ You would take the "ln" (that is, "natural logarithm") of EACH side of the equation:
ln (e^4x) = ln (120);
______________________
Then continue:
4x ln e = ln 120
4x = ln 120 ; (since "ln e = 1")
then divide EACH side of the equation by "4", to isolate "x" on one side of the equation; and to solve for "x" ;
___________________________________
4x / 4 = (ln 120) / 4 ;
___________________________
x = (ln 120) / 4 ;
______________________________
Using a calculator:
_________________________________________________________
x = (ln 120) / 4 = (4.78749174278) / 4 = 1.1968729357

Answer:
16,507.38
Step-by-step explanation:
The equation for this would be 8600(1 + 0725/52)^52*9
9 is the years, 52 is the compounded weekly, and 8600 is the initial amount.
Solving the equation, we get:
16,507.38
Answer:y=200 students
Step-by-step explanation:Let x = the number of adult tickets sold
Let y = the number of student tickets sold
x + y = 375 x = 375 - y
7.50x + 4.50y = 2212.50 Multiply both sides of this equation by 10 to remove the decimal points.
75x + 45y = 22,125
75(375-y) + 45y = 22,125
28,125 - 75y + 45y = 22,125
-30y = -6000
y = 200 student tickets
