First put it in decreasing power according to x.
x^4-5x+8+x^2
=x^4+x^2-5x+8
Now this question is asking what is the highest degree of x you see in this function.
4 of course.
Therefore the answer to his question is degree of 4.
Done!
Volume of water in the tank:
Differentiate both sides with respect to time <em>t</em> :
<em>V</em> changes at a rate of 2000 cc/min (cubic cm per minute); use this to solve for d<em>h</em>/d<em>t</em> :
(The question asks how the height changes at the exact moment the height is 50 cm, but this info is a red herring because the rate of change is constant.)

I think 160! I don't know it true or not
Answer: Mr. Shahoian need to purchase 9 pieces of fencing.
Step-by-step explanation:
Given: Length of fencing around the flower beds in his backyard = 166.25 ft
The fencing is sold in lengths of 19 ft each.
Number of pieces of fencing = (Length of fencing ) ÷ (19)
i.e. Number of pieces of fencing = 166.25 ÷ 19
= 8.75 ≈ 9
Hence, Mr. Shahoian need to purchase 9 pieces of fencing.
