Give an example of: degree of a polynomial is the highest sum of one of its terms, explain.
yuradex [85]

Example 1  Perform the indicated operation for each of the following.

<span>(a) </span>Add  to 

<span>(b) </span>Subtract   

Solution

(a) Add  to .

The first thing that we should do is actually write down the operation that we are being asked to do.

                                          

In this case the parenthesis are not required since we are adding the two polynomials.  They are there simply to make clear the operation that we are performing.  To add two polynomials all that we do is combine like terms.  This means that for each term with the same exponent we will add or subtract the coefficient of that term.

 

In this case this is,

(b) Subtract  from .

Again, let’s write down the operation we are doing here.  We will also need to be very careful with the order that we write things down in.  Here is the operation

Can someone please help I pay £100
Flura [38]

Answer:

The new points to the triangle will be:
A(1,4)\\ B(1,1)\\ C(-1,1)

Step-by-step explanation:

Because the reflection point is at x=2, all x values will subtract their distances from x=2 to get their new values. The y values remain the same.

The starting values are:

A(3,4)\\ B(3,1)\\ C(5 ,1)

Point A is 1 unit away from x=2, so we'll subtract 1 from 2 to get the new x value: 2 - 1 = 1, so A(1,4).

 

Point B is also 1 unit away from x=2, so we'll subtract 1 from 2 to get the new x value: 2 - 1 = 1, so B(1,1).

Point C is 3 units away from x=2, so we'll subtract 3 from 2 to get the new x value: 2 - 3 = -1, so C(-1,1).

Find the missing angle
dangina [55]

Answer:

95 degrees

Step-by-step explanation:

The given shape is a triangle.

Let the missing angle be " x ".

Sum of interior angles in a triangle is 180 degrees,

x + 45 + 40 = 180

x + 85 = 180

Subtract 85 on both sides,

x = 180 - 85

x = 95 degrees

What Is Tan A<br> What IS Tan C
Alexandra [31]

Tan C

Tangent (tan) function - Trigonometry. ... In a right triangle, the tangent of an angle is the length of the opposite side divided by the length of the adjacent side.

Tan A

The tangent function, along with sine and cosine, is one of the three most common trigonometric functions. ... In any right triangle, the tangent of an angle is the length of the opposite side (O) divided by the length of the adjacent side (A). In a formula, it is written simply as 'tan'.
