Answer:

linear

Step-by-step explanation:

The easiest (if not the only) way to solve this, is to check whether the slope at each point stays constant, or not. And in general, see how the rate rate of change evolves. In other words:

6.5 / 5 = 1.3
13 / 10 = 1.3
19.5 / 15 = 1.3
26 / 20 = 1.3
32.5 / 25 = 1.3
39 / 30 = 1.3

As you can see " in every step to the right, the function goes up by 1.3 " --> constant

So, the function is linear

Which expressions are polynomials? Select each correct answer. 30y^2 30y^2+x 30y2x 30y2+x12

gregori [183]

To know which of the following expressions are polynomials, let us look at the definition of a polynomial:

Polynomial is derived from poly- (which means "many") and -nomial (meaning "term"), so it says "many terms".

For an instance: $2x^2y+2y^2$ is a polynomial, but $4xy^2$ is not a polynomial because it contains single term only.

We must keep in mind that in polynomial it can have variables, constants, and exponents but it can never have division by a variable.

Now lets, look at the

$30y^2$ since it has got one term it can not be a polynomial.

$30y^2+x$ : it has got more than one term therefore, it is a polynomial.

$30y^2x$ : again it has got just one term so it is not a polynomial.

$30y^2+x^{12}$ : Since it has got more than one term, so again it is a polynomial.

The length of each side of the star is eight units what is the perimeter of the star

Minchanka [31]

Answer:

80 units

Step-by-step explanation:

The star has 10 sides. If each side is 8 units, then the perimeter is 10(80) because the perimeter is the sum of the lengths. With each length being 8, you could add 8 to itself 10 times, but it is faster to multiply.
