Mathematics

Answer:

Closure property

Step-by-step explanation:

The closure property of polynomials for addition says that, if we add any two polynomials , the result is also a polynomial.

For is

{x}^{2}  + 2

is a polynomial.

x - 2

is also a polynomial.

The sum of the two polynomials is

{x}^{2}  + 2  + x - 2 =  {x}^{2} + x

The result:

{x}^{2}  + x

is also a polynomial.

How to do this plastic help​
liraira [26]

Answer:

39 degrees

Step-by-step explanation:

  • by seeing the diagram in the attachment, we can see that the angles UWV and VWX are on straight line or, their sum makes 180 degrees.
  • we also know that sum of the angles in a triangle is 180 degrees.

by using the first statement,

UWV + VWX = 180

UWV + 6x-3 = 180

UWV = 180+3-6x

         = 183-6x

by using second statement,

UWV+WVU+VUW=180

substituting the values,

183-6x+2x+5+x+13=180

201-3x=180

substracting 180 from both sides,

21=3x

dividing both the sides by 3,

7=x

the angle VWX=6x-3

substituting 7=x,

VWX=6(7)-3= 39.

$668 at 9.25% for 5 years
madreJ [45]

Answer:

$21.17

Step-by-step explanation:

Simple Interest=P(1+r)^t

Compounded Interest=P(e^rt)

SI=668*(1.0925)^5

SI=1039.64

CI=668(e^(0.0925*5))

CI=1060.81

1060.81-1039.64=21.17

So the difference is $21.17, thus doing compounded interest is better.

Gerald graphs the function f(x) = (x – 3)2 – 1. Which statements are true about the graph? Check all that apply.
Bumek [7]
Please use " ^ " to indicate exponentiation.  Then:  <span>f(x) = (x – 3)^2 – 1.
By comparing this equation to                                  y-k  = (x-h)^2
you can see that h=3 and k= -1.  Thus, the vertex is at (3, -1).
The axis of symm. goes thru the vertex, so is x = 3.
The domain is the set of all real numbers.
Since the vertex is (3, -1), the smallest value y can take on is -1.  Thus, the range is [-1, infinity)
