Write the answer in scientific notation (5.4 × 10 to the power of 8) (3.2 × 10 to the power of 6)

1,728 × 10 to power twelve

Step-by-step explanation:

(5.4 × 100000000)(3.2×1000000)

(540,000,000)(3,200,000)

1,728,000,000,000,000

1,728 × 10 to power twelve

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.

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.
