What is the second term of (2x 2 ‑ 3y)^6 ? your answer should be in the form (sign)(numerical factors)(actual powers of variables).

.

Step-by-step explanation:

Use the binomial theorem: given any variables a,b and a positive integer n, .

In this case, take

Usually, the terms on a polynomial of two variables are ordered starting with the highest power of x (x^12 in this case) and the lowest power of y. The powers of x decrease and the powers of y increase, so the last term has the highest power of y and the lowest power of x .

Then, the second term is k=1 as it has the second highest power of x, so replacing these values this term is:

.

your answer would be 12

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
