A binomial expansion is given by (a + b)^n = ∑nCk * a^(n - k) * b^k, k = 0, 1, 2 , . . . n
The third term is the term for k = 2.
The third term = 4C2 * (3x^2)^(4 - 2) * (2y^3)^2 = 6 * 9x^4 * 4y^6 = 216x^4y^6
Therefore, the coefficient of the third term is 216.
The answer will be Proportional
First you have to ask, how many minutes are in a day?
There are 60 minutes in a hour, and 24 hours a day. You would multiply these two to find how many minutes are in a day.
24×60=1440 minutes in a day.
Now to find how many passages a minute, divide the total number of passangers, by the number of minutes.
191,200÷1440=132.7778
Even though the 7 is bigger than a 5, you do not round up because it doesn't count as a full person.
132 people a minute is your answer.
Answer:
Suppose 3 consecutive integers are X-1,X,X+1
Step-by-step explanation:
Sum = X-1+X+X+1= -78
3X=-78
X= -78/3
X= -26
3 consecutive integers are, -27, -26,-25.
smallest integer is -27
Answer:
positive
Step-by-step explanation:
If the variables tend to increase and decrease together, the association is positive.
