Answer:
Step-by-step explanation:
The first answer a, is not a linear function because of the first term, 2√(x), this is basically 2(x^(1/2)) which means that it is not linear
B is linear because there are no exponents in any of the variables.
C is not linear because it forms a circle when graphed
D is linear because there are no exponents in any of the variables.
E is linear because there are no exponents in angy of the variables.
F is linear because there are no exponents in any of the variables.
G is not linear because it is a quadratic equation.
 
        
                    
             
        
        
        
Answer:
Step-by-step explanatiArea of Composite Shapes. Composite shapes are shapes that have a combination of 2-D shapes. To find the area of composite shapes you just need to break down the shape into individual pieces and calculate their separate pieces then add them back together again to find a total areaon:
 
        
             
        
        
        
Answer:
 is isosceles.
 is isosceles.
Step-by-step explanation:
Please have a look at the attached figure.
We are <u>given</u> the following things:


Let us try to find out  and
 and  . After that we will compare them.
. After that we will compare them.
<u>Finding </u> <u>:</u>
<u>:</u>
Side EG is a straight line so 
 is sum of internal
 is sum of internal  and external
 and external 
 
 
<u>Finding </u> <u>:</u>
<u>:</u>
<u>Property of external angle:</u> External angle in a triangle is equal to the sum of two opposite internal angles of a triangle.
i.e. external  =
 = 

Comparing equations (1) and (2):
It can be clearly seen that:

The two angles of  are equal hence
 are equal hence  is isosceles.
 is isosceles.
