Answer:
A
Step-by-step explanation:
Any number that have the | | symbol will automatically be positive
For example
| -5.8 | = 5.8
Answer:
$30.00
Step-by-step explanation:
price of dress x 8% = $2.40
price of dress = 2.40/.08
price of dress = $30.00
The function is written as:
f(x) = log(-20x + 12√x)
To find the maximum value, differentiate the equation in terms of x, then equate it to zero. The solution is as follows.
The formula for differentiation would be:
d(log u)/dx = du/u ln(10)
Thus,
d/dx = (-20 + 6/√x)/(-20x + 12√x)(ln 10) = 0
-20 + 6/√x = 0
6/√x = 20
x = (6/20)² = 9/100
Thus,
f(x) = log(-20(9/100)+ 12√(9/100)) = 0.2553
<em>The maximum value of the function is 0.2553.</em>
Answer:
decay rate is -13 percent in an hour. 3 hours would be (0.87)^3 = 65.85 percent
