Which algebraic expression is a polynomial with a degree of 3?

1 answer:

7 0

It would be the second choice. This expression is a polynomial because it is multiple terms and is a degree of three because the largest exponent is three. So your answer is:
2y^3 + 5y^2 - 5y

Wendy is logging the number of video game levels she wins per hour. She has determined the function to be f(x) = 6x + 9, where x

Savatey [412]

The answer is C because spending no time on video games gets you at least 9 for a range, and spending as much time as she wants to means the number will increase meaning "greater than"

Determine a series of transformations that would map polygon ABCDE onto polygon A’B’C’D’E

zalisa [80]

Answer:

Reflected across x-axis followed by a dilation with a scale factor of 2 about the origin.

Step-by-step explanation:

It's clear from the graph,

Polygon ABCDE is reflected across x-axis then dilated so that it overlaps polygon A'B'C'D'E'

Let's choose a point A having coordinates (-2, -1)

By reflecting point A across x-axis,

Rule to be followed for the reflection,

(x, y) → (x, -y)

By this rule, coordinates of the image point A will be,

A(-2, -1) → A"(-2, 1)

Now point A"(-2, 1) has been dilated by a scale factor = k to form an image points A'(-4, 2).

Rule for the dilation of a point about the origin is,

A"(x, y) → A'(kx, ky)

A"(-2, 1) → A'(-2k, k)

Since, coordinates of point A' are (-4, -2),

Therefore, -2k = -4

k = 2

Hence, polygon ABCDE was reflected across x-axis followed by a dilation with a scale factor of 2 about the origin to form polygon A'B'C'D'E'.

Answer:

Ryan should mark the price as $300.

A couple of college students frustrated with the current class registration process decide to survey 500 random students on camp

aleksklad [387]

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Standard deviation = $\sqrt{(n*p)(1 - p)}$

Substitute the values in:

$\sqrt{(500 *0.84)(1-0.84)}$ = 8.1975...

This can be rounded to give an approximate answer of 8.2

The answer is option A.
