Answer/Step-by-step explanation:

Part A:

If a figure is divided into two equal halves by a line of symmetry, each of the pair the corresponding parts will be congruent to the other part.

Thus, based on the Symmetric Figures Theorem, the two parts in the question above are congruent as a result of the line of symmetry, line SD, which makes one part the mirror image of the other.

Therefore, Noah's congruence statement is of the pentagons is incorrect.

Part B:

Based on Symmetric Figures Theorem, AXPDS is congruent to MHZDS as the line of symmetry, line SD, makes one a mirror image of the other.

The line of symmetry of the quadrilateral AXPDZHMS = The line SD

Therefore, given that SD is congruent to SD by reflexive property, we have;

AXPDS is congruent to MHZDS

Part a: The reason why Noah's congruency statement is incorrect is the

order of the lettering in the statement, and the part of the selected that do

not directly show congruency, which are;

Part b: The correct congruency statement is presented as follows;

I'm sorry I haven't read the book in a long time but here are some tips.

Only talk about the events that susan would know about. Don't talk about john at home and things like that.

Make sure you use words that shows Susan is not happy like hate, stupid, etc. Not sure if you are girl or boy, but make sure you talk about all the little details that girls would think about. Like john getting chocolate on Susans dress. You could also talk more about the coin and what she was going to do with it(you can make something up cuz teachers give points for creativity.)

Answer:

-5.6

Step-by-step explanation:

Given parameters:

 Temperature at Alto  = -3.8°C

Unknown:

The wind chill temperature  = ?

Solution:

Due to the windchill, temperature in Alto feels colder at -3.8.

We can infer that usually, the temperature in Alto is not supposed to be up to this value. The windchill reduced the temperature;

 Temperature in Alto = Original temperature + wind chill temperature

Originally, the temperature would be = -3.8 + 5.6 = 1.8

So;

     -3.8 = 1.8 + wind chill temperature

   Wind chill temperature  = -3.8 - 1.8 = -5.6

No I don't, I never really heard any music from them, but that doesn't mean you can't like that type of music.

Anyway have a nice day! :D

Yes, I love NF's music. I especially love his song "Mansion" because the lyrics are profound and deep; it really resonates with me. All in all, I love all, if not most, of his songs, and I can play them on repeat. I can't wait for him to release new music. I hope he garners more attention because he's really underrated.

Answer:

Shampoo number one has a lower unit rate

It is lower by 10 cents

Step-by-step explanation:

To find the unit rate for bottle one do 6/8 which is 0.75 so for bottle one, one ounce of shampoo cost 75cents

For shampoo two do 4/5 = 0.8 so for every one ounce it costs 80 cents

So shampoo number one has a lower unit rate

and it is 80-70= 10 cents lower

Hope this helps!

Answer:

x = 5

x = 2

x = -6

Step-by-step explanation:

Use synthetic division to determine whether x – 4 is a factor of:

–2x5 + 6x4 + 10x3 – 6x2 – 9x + 4

For x – 4 to be a factor, you must have x = 4 as a zero. Using this information, I'll do the synthetic division with x = 4 as the test zero on the left:

completed division

Since the remainder is zero, then x = 4 is indeed a zero of –2x5 + 6x4 + 10x3 – 6x2 – 9x + 4, so:

Yes, x – 4 is a factor of –2x5 + 6x4 + 10x3 – 6x2 – 9x + 4

Find all the factors of 15x4 + x3 – 52x2 + 20x + 16 by using synthetic division.

Remember that, if x = a is a zero, then x – a is a factor. So use the Rational Roots Test (and maybe a quick graph) to find a good value to test for a zero (x-intercept). I'll try x = 1:

completed division

This division gives a zero remainder, so x = 1 must be a zero, which means that  x – 1 is a factor. Since I divided a linear factor (namely, x – 1) out of the original polynomial, then my result has to be a cubic: 15x3 + 16x2 – 36x – 16. So I need to find another zero before I can apply the Quadratic Formula. I'll try x = –2:

completed division

Since I got a zero remainder, then x = –2 is a zero, so x + 2 is a factor. Plus, I'm now down to a quadratic, 15x2 – 14x – 8, which happens to factor as:

(3x – 4)(5x + 2)

Then the fully-factored form of the original polynomial is:

15x4 + x3 – 52x2 + 20x + 16

= (x – 1)(x + 2)(3x – 4)(5x + 2)

Given that  x = -3 + sqrt(11)   is a zero of x4 + 6x3 – 7x2 – 30x + 10, fully solve the

equation x4 + 6x3 – 7x2 – 30x + 10 = 0.

Since they have given me one of the zeroes, I'll use synthetic division to divide it out:

completed division

Since you only get these square-root answers by using the Quadratic Formula, and since the square-root part of the Formula is preceded by a "plus-minus" sign, then these square-root answers must always come in pairs. Thus, if x = -3 + sqrt(11) is a root, then so also must x = -3 - sqrt(11) be a root. So my next step is to divide by x = -3 - sqrt(11):

completed division

I had started with a fourth-power polynomial. After the first division, I was left with a cubic (with very nasty coefficients!). After the second division, I'm now down to a quadratic (x2 + 0x – 5, or just x2 – 5), which I know how to solve:

x = +/- sqrt(5)

Then the full solution is:

x = -3 +/- sqrt(11), +/- sqrt(5)

If you have studied complex numbers, then you may see a problem of the following type.

Given that 2 – i is a zero of x5 – 6x4 + 11x3 – x2 – 14x + 5, fully solve the

equation  x5 – 6x4 + 11x3 – x2 – 14x + 5 = 0.

They have given us a zero, so I'll use synthetic division and divide out 2 – i:

completed division

(You will probably want to use scratch paper for the computations required when doing complex division.)

Recall that, to arrive at a zero of 2 – i, they must have used the Quadratic Formula, which always spits out complex answers in pairs. That is, you get the imaginary part (the part with the "i") from having a negative inside the "plus or minus square-root of" part of the Formula. This means that, since 2 – i is a zero, then 2 + i must also be a zero.  So I'll divide by 2 + i:

completed division

This leaves me with a cubic, so I'll need to find another zero on my own. (That is, I can't apply the Quadratic Formula yet.) I can use the Rational Roots Test to help find potential zeroes, and a quick graph of x3 – 2x2 – 2x + 1 can help. I will try x = –1:

completed division

Now I'm down to a quadratic (x2 – 3x + 1, which happens not to factor), so I'll apply the Quadratic Formula to get:

x = (3 +/- sqrt(5))/2

Then all the zeroes of x5 – 6x4 + 11x3 – x2 – 14x + 5 are given by:

x = 2 - i, 2 + i, (3 - sqrt(5))/2, (3 + sqrt(5))/2, -1
