Answer: This is an reduction.
Step-by-step explanation:
- A dilation a king of transformation that creates an similar image (about a center of dilation) of the actual figure by changing its size with the use of a scale factor(k).
- It either shrinks or stretches the image.
- If |k| is greater than 1 then the image is an enlargement .
- If |k| is less than 1 then the image is an reduction.
- If |k| is equals to 1 then there is no change in size.
Given : A street is drawn by dilating segment 
about center A with a scale factor greater than 0 but less than 1.
Then by using (2.) , we can say that this is an reduction.

Answer: -3x^4-4
Step-by-step explanation: -3x^4+4-8 > =-3x^4-4
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.
