Part 1 (Unit 2): Subtract Polynomials:

Mathematics
1 answer:
Alinara [238K]3 years ago
8 0
Part 1
 We have the following polynomials:
 (3-6n5-8n4)
 (-6n4-3n-8n5)
 Subtracting the polynomials we have:
 (3-6n5-8n4) - (- 6n4-3n-8n5)
 n5 (-6 + 8) + n4 (-8 + 6) + 3n + 3
 Rewriting:
 2n5 - 2n4 + 3n + 3

 
Part 2
 
For this case we have the following polynomial:
 4x2-2x-5 = 0
 Using resolver we have:
 x = (- b +/- root (b ^ 2 - 4 * a * c)) / (2 * a)
 x = (- (- 2) +/- root ((- 2) ^ 2 - 4 * 4 * (- 5))) / (2 * 4)
 x = (2 +/- root (4 + 80)) / (8)
 x = (2 +/- root (84)) / (8)
 x = (2 +/- root (4 * 21)) / (8)
 x = (2 +/- 2raiz (21)) / (8)
 x = (1 +/- root (21)) / (4)
 The roots are:
 
x1 = (1 + root (21)) / (4)
 
x2 = (1 - root (21)) / (4)

Answer:

C.  no solutions

Step-by-step explanation:

Both equations have a slope of -2, but have different y-intercepts.  Therefore, the graphs of the equations are parallel, but don't coincide, nor do they intersect.  So, there are no solutions

A point A is graphed at (0, 3). Complete the coordinates of a shape that can be rotated about the y-axis to create a cylinder
babymother [125]
Below is the answer:

Any rectangle with a side against y-axis can be rotated about y-axis to create a cylinder. 

<span>The other 3 coordinates will be (a, 3), (a, b), (0, b) </span>

<span>This will be a cylinder of radius a and height |3−b|</span>

What transformation has changed the parent function f(x) = log4 x to its new appearance shown in the graph below?
Lostsunrise [7]
I think you forgot to attach the graph along with the question. I am answering the question based on my research. "f(x + 5) + 5" is the one transformation among the following choices given in the question that <span>has changed the parent function f(x) = log4 x to its new appearance. The correct option among all the options that are given in the question is the fourth option.</span>

Question is in png pls some1 help !

Answer:

Triangle x = 30. Pentagon x = 50

Step-by-step explanation:

For the triangle,

Find the angle which is beside x in the triangle,

let's name that angle y, so 55 + 55 + y = 180 ( we find 55 by subtracting both angles 125 from 180)

110 + y = 180

Y = 180 - 110

y = 70

Now that we have find Y, we can easily find x by subtracting 70 from 180 which would be, 70 + X = 180

x = 180 - 70

x = 30

For the pentagon,

Again find the angle which is beside x in the pentagon,

let's name that y again, 90 + 120( by subtracting 60 from 180) + 110( by subtracting 70 from 180)  + 90 + y = 540

210 + 200 + y = 540

410 + y = 540

y = 540 - 410

y = 130

Now that we have find y, we can easily find x by subtracting 130 from 180 which would be, 130 + x = 180

x = 180 - 130

x = 50

Hope this helps!
