Answer:

17.) 18^{4} + 2x^{3} - 14x^{2}

18.) 9x^{5} + 27x^{4}

19.) -12y^{3} - 12y^{2} - 12y - 12

20.) x^{2} + 9x + 20

21.) 4x^{2} - 5x - 6

22.) m^{6} +2m^{5} + m^{4}

23.) 2 m ^{7}+ 3 m ^{6} + 2 m ^{4} + 10 m ^{3} + 15 m^{ 2} + 10

Step-by-step explanation:

17.) Distribute 2x^{2} to all of the terms in the parenthesis.

18.) Combine Like Terms (x and 9x^{4}\\) Multiply all other terms by 9x^{4}

19.) Multiply terms within the separate parenthesis together

20.) Use FOIL and expand the polynomial

21.) Use FOIL and expand the polynomial

22.) Combine like terms and multiply the contents of the parenthesis by the exponent

23.) Expand  ( m^{ 4} + 5 ) ( 2 m^{ 3} + 3 m ^{2} + 2 )  by multiplying each term in the first expression by each term in the second expression.

Part 1 state the domain and range of the given relation.
hram777 [196]
A relation is any set of ordered pairs, which can be thought of as (input, output).

A function is a relation in which NO two ordered pairs have the same first component and different second components.

The set of first components (x-coordinates) in the ordered pairs is the DOMAIN of the relation.

The set of second components (y-coordinates) is the RANGE of the relation.

Part 1:
Domain: {-1, 1, 3, 6}
Range: {2, 2, 2, 2}

Part 2:
To determine whether the given relation represents a function, look at the given relation and ask yourself, “Does every first element (or input) correspond with EXACTLY ONE second element (or output)?”

Remember that a function can only take on 1 output for each input.

It helps to plot the points on the graph and perform the Vertical Line Test (VLT):

The Vertical Line Test allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.

As you can see in the attached screenshot, every vertical line drawn only has 1 point in it. This means that each x-value corresponds to exactly one y-value. The given relation passed the VLT. Therefore, the relation is a function.

On a True/False test, Amy answered the first three questions wrong but answered the rest of the questions correctly. On the same
borishaifa [10]

Answer:

89.29%

Step-by-step explanation:

Given that Scott answered exactly two questions wrong. He answered the last question wrong, the 26 questions before it correctly, and the question before that wrong.  Since Amy and Scott were both incorrect on the same question exactly once, Scott would have done wrong only in I or II or III question.  If I question was wrong by both, total questions = 28, if II wrong total questions =29 and for iii total questions =30

Greatest possible percent would occur if total questions are less

i.e. when total =28

Greatest percent = \frac{28-3}{28} =89.29%
