1. 7/15 = 63/135
2. 6/13 = 48/104
hope this will help you
Answer:
It's positive when you have 6^-2 it's the same as having
. So 6^-2 it's 1/36.
Step-by-step explanation:
Answer:

Step-by-step explanation:
First at all, we need to use
to convert this expression into a fraction, like:
to convert into
.
Expand the fraction to get the least common denominator, like

Write all numerators above the common denominator, like this:

The bottom one used the same way to became simplest form, like this:




And it became like this:

Now, we are going to simplify this complex fraction. We can use cross- multiply method to simplify this fraction.

3y-2(5) and 5y-1(3)
and it will becomes like this in function form:

Then, we should distribute 5 through the parenthesis


And.... Here we go. That is the answer.
It is the first option i think
R(x) = 60x - 0.2x^2
The revenue is maximum when the derivative of R(x) = 0.
dR(x)/dx = 60 - 0.4x = 0
0.4x = 60
x = 60/0.4 = 150
Therefore, maximum revenue is 60(150) - 0.2(150)^2 = 9000 - 4500 = $4,500
Maximum revenue is $4,500 and the number of units is 150 units
