Answer:
x+y=$8,000 i guess
Step-by-step explanation:
Answer:

Step-by-step explanation:
0.3
^ You need to move the three before the decimal place and leave 4 empty digits (0) between
0.3
3.0
30.0
300.0
3000.0
30000.0
A total of 5 moves.
Each move is equivalent to x, the preceding value, times 10. x * 10
Repeated multiplication times the same factor equates to exponentiation, so for a total of 5 moves, it is notated as
, giving you an expression of:

Get n by itself in both inequalities
(This program doesn't allow for regular less than or greater than signs, so for the purposes of this problem I will be using less than or equal to (≤) and greater than or equal to (≥) signs)
Inequality 1:

Inequality 2:

Now that you have both of the n's by themselves, you can put the two inequalities together, like this

Just keep in mind that these are supposed to be regular less than signs
They both have the same number. The decimal point changed their values
Hope this helps! :)
Step-by-step explanation:
A fence for a rectangular garden with one side against an existing wall is constructed by using 60 feet of fencing.
Perimeter of rectangle (3 sides)= 60 feet
Let 'x' be the width of the wall

Formula for the area of the rectangle is

Replace the length we got using perimeter

To find out the maximum are we take derivative

find out second derivative to check whether x=15 is maximum

second derivative is negative
So, Maximum area at x=15
To find maximum area we plug in 15 for x in A(x)

So, maximum area is 225 square feet
