lisov135 [29]
You should first draw a strait line across your paper. Draw the 55 degree angle with your protractor. Then draw the 125 degree angle it should stop at where the line of the 55 degree angle you just drew. These two angles add up to 180 degrees. 125+55 = 180. These are known as supplementary angles.

How do you determine the degree of a power function from a table? When do you know you have successfully determined the degree o
svp [43]

Answer:

A power function is a function that can be represented in the form

f(x)=kx^p

where k and p are real numbers, and k is known as the coefficient.

Example:

f(x)=1    constant function.

f(x)=x     identity function

f(x)=x^2   quadratic function.

1)

we use the method of differences, g(x+1)-g(x). Keep taking differences until they are all constant.

for example:

if we have a set of values as:

 x         g(x)

−2       −8


−1       −1


 0        0


 1        1


 2        8

Now when we find the difference as:

<u>x</u>       <u>g(x)</u>        <u>  D1 </u>           <u>   D2    </u>               <u>   D3</u>



-2       -8



-1         -1        1-(-8)=7



0          0       0-(-1)=1          1-7=-6



1            1       1-0 = 1           1-1=0               0-(-6)=6



2           8       8-1 = 7          7-1=6               6-0 = 6

As D3 is constant hence, the degree of the power function is 3.

2)

When we get a constant difference in the table of the difference method we will successfully get our degree.

Help with simultaneous equations!! <br>Plz could you help me work these 3 questions out. Thanks.
garik1379 [7]
To solve these types of questions, all what you need to do is simply solve for any one of the variables provided above and substitute the solved variable for the other equation. For instance in the first example:

X/2 - 2y = 5
12y + X - 2 = 0

X = 2 - 12y

(2 - 12y)/2 - 2y = 5
(2 - 12y)/2 = 2y + 5
2 - 12y = 2(2y + 5)
2 - 12y = 4y + 10
16 y + 8 = 0
16y = -8
Y =-8/16 = -1/2.

X = 2 - 12(-1/2)
X = 2 + 6
X = 8.

P(X, y) = P(8, -1/2).

Do the same method, for the other questions, except simplify them before doing so.
