Answer:the coefficient of k is 1/7
Step-by-step explanation:
The given expression is
P(k)=k/7+k^4+3
The coefficient of k is the number before the term k. The number before the term, k is 1/7
Answer: 11
Step-by-step explanation: You divide 495/45 and you get 11
Complete the square by adding the square of half of four to both sides (4)
x^2+y^2-4y+4=4
x^2+(y-2)^2=4
You subtract normally inside the absolute value (the two bars):
-4-3 is -7
Since the negative is INSIDE the absolute, the answer will turn to a positive. Think of the bars as a jail cell for the negatives. Once the negatives are in there, only positive numbers will come out. So your answer is 7.
