Answer:
e^(ln x) is just plain x
Step-by-step explanation:
The functions f(x) = e^x and g(x) = ln x are inverses of one another. In other words, one "undoes" the other.
Thus, as the rule goes, e^(ln x) is just plain x.
Here, e^(ln x) = 4 simplifies to x = 4.
83 + 94 + 79 + 97 + 96 + 87 = 536.
536 ÷ 6 = 89.333333...
So, Lamonts' average is under 90.
Answer:
Step-by-step explanation:
10% discount means you pay 90% of the original cost x.
90% of x = $40.50
0.90x = $40.50
x = $40.50/0.90 = $45
:::::
total cost = 1.065·$40.50 ≅ $43.13
