Radius of circle with center R' : 6 units
Scale factor :
- Radius of dilated circle /Radius of original circle
- 6/2
- <u>3</u>
Whenever you face the problem that deals with maxima or minima you should keep in mind that minima/maxima of a function is always a point where it's derivative is equal to zero.
To solve your problem we first need to find an equation of net benefits. Net benefits are expressed as a difference between total benefits and total cost. We can denote this function with B(y).
B(y)=b-c
B(y)=100y-18y²
Now that we have a net benefits function we need find it's derivate with respect to y.

Now we must find at which point this function is equal to zero.
0=100-36y
36y=100
y=2.8
Now that we know at which point our function reaches maxima we just plug that number back into our equation for net benefits and we get our answer.
B(2.8)=100(2.8)-18(2.8)²=138.88≈139.
One thing that always helps is to have your function graphed. It will give you a good insight into how your function behaves and allow you to identify minima/maxima points.

Answer:
there is no answer
Step-by-step explanation:
If you multiply 15^x by 15^y, the answer is 15^(x+y) so 2 plus -7 is negitive 5.
but there is no answer equal to this.
