lianna [129]

Answer:

Step-by-step explanation:

Part of the definition of a polynomial is that the exponents have to be non-negative integers.  In other words, it cannot have a fraction as an exponent or an imaginary number.  Our polynomial has real non-negative exponents, so it is in fact a polynomial.  The degree is found in the highest exponent of the polynomial.  Ours is a 5th degree.  The leading coefficient is the number stuck to the x that has the highest degree.  Therefore, our leading coefficient is -16.  B is your choice.

An object traveled a total of 21 1/2 miles in five hours. If it traveled an equal number of miles each hour, how many miles did
GenaCL600 [577]

Answer:   4.3 miles

The decimal 4.3 is equivalent to the mixed number 4 & 3/10

=============================================================

Explanation:

Fractions are often a pain, so I find it helpful to convert to decimal form whenever possible.

1/2 = 0.5

21 & 1/2 = 21 + 1/2 = 21 + 0.5 = 21.5

21 & 1/2 miles = 21.5 miles

The object travels 21.5 miles in 5 hours. Divide the distance over the time value to get the speed (or rate). This is exactly identical to finding the number of miles traveled in one hour (since each hour the object travels the same amount of distance)

speed = distance/time = 21.5/5 = 4.3 mph

4.3 = 4 + 0.3 = 4 + 3/10 = 4 & 3/10

In my opinion, it is much easier to use decimals. Saying "the object traveled a distance of 4 & 3/10 miles" seems very clunky to me.

Therefore, each hour, the object travels 4.3 miles.
