Answer:

$-x^{4}+8x^{3}-17x^{2} +16\\\\=-x^{4}+4x^{3}+4x^{3}-16x^{2} -x^{2} +16\\\\=-x^{3}(x-4)+4x^{2}(x-4)-(x-4)(x+4)\\\\\\=(-x^{3}+4x^{2}-x-4)(x-4)\\\\ =>\frac{-x^{4}+8x^{3}-17x^{2} +16}{x-4}= (-x^{3}+4x^{2}-x-4)+\frac{0}{x-4}$

What is 1 /7 as a decimal rounded to 3 decimal places?

Nostrana [21]

Answer:

0.143

Step-by-step explanation:

You need to convert 1/7 to have a denominator of either 100 or 10. We can do 100.

1/7 = ?/100

then you need to divide 100/7 to find the scale factor which in this case is 14.286

then you can insert it into the equation

1/7 = 1 * 14.286/100

you end up with

14.286/100

then you can dived the two

0.14286 is what you end up with

but since it says rounded to the 3rd decimal place you go to the 3rd which is 2.

To round it you look at the 4th number which is 8.

<em>5 and above give it a shove up</em>

So now its 0.143

Hope this helped :)

I will give BRAINLIEST! HELP PLEASE.!!!<br><br> 2. Find each measure. <br> m<1 m<2 m<3

fredd [130]

<h3>Answer: Choice B</h3>

Angle 1 = 147 degrees

Angle 2 = 80 degrees

Angle 3 = 148 degrees

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

Work Shown:

(angle 1) + 33 = 180

angle 1 = 180-33

angle 1 = 147 degrees

---------------

Focus on the left most triangle that has angles 33 and 47 as interior angles. The missing angle is 180-33-47 = 100 degrees

The angle exterior to this 100 degree angle is angle 2

angle 2 = 180-100 = 80

We have enough info to conclude the answer must be choice B.

---------------

Let's keep going to find angle 3

The vertical angle for the 100 degree angle is also 100 degrees. This second 100 degree angle is part of the triangle on the right

This triangle on the right has interior angles 100 and 48

The missing interior angle is 180-100-48 = 32

The angle supplementary to this is 180-32 = 148, which is angle 3.

Consider a Triangle ABC like the one below. Suppose that C = 98, A = 74, and b = 11 (figure is not drawn to scale.) solve the tr

Degger [83]

Answer:

$A=73.8\°$

$B=8.2\°$

$c=76.3\ units$

Step-by-step explanation:

step 1

Find the measure of side c

Applying the law of cosines

$c^{2}= a^{2}+b^{2}-2(a)(b)cos(C)$

substitute the given values

$c^{2}= 74^{2}+11^{2}-2(74)(11)cos(98\°)$

$c^{2}=5,823.5738$

$c=76.3\ units$

step 2

Find the measure of angle A

Applying the law of sine

$\frac{a}{sin(A)}=\frac{c}{sin(C)}$

substitute the given values

$\frac{74}{sin(A)}=\frac{76.3}{sin(98\°)}$

$sin(A)=(74)sin(98\°)/76.3$

$A=arcsin((74)sin(98\°)/76.3)$

$A=73.8\°$

step 3

Find the measure of angle B

we know that

The sum of the internal angles of a triangle must be equal to 180 degrees

$A+B+C=180\°$

substitute the given values

$73.8\°+B+98\°=180\°$

$171.8\°+B=180\°$

$B=180\°-171.8\°=8.2\°$

Answer:

1) $\frac{-8}{11}$

2) $1.276$

3) $\frac{3}{4}$

4) $0$

Step-by-step explanation:

The slope formula of the line that pass across two points P1(x1,y1) and P2(x2,y2) is:

$\frac{y2 - y1}{x2-x1} = slope$

You can use this formula to solve all the four points:

$\frac{6- -2}{-9 - 2} = \frac{-8}{11}$

$\frac{- 9.1 - 0.6}{-9.5 - - 1.9} = \frac{97}{76} =(Rounded)= 1.276$

$\frac{2-5}{-2 -2} = \frac{3}{4}$

$\frac{4-4}{-9 --4} = \frac{0}{-5} = 0 \\\\$
