Answer:
 is not equal to
 is not equal to 
Step-by-step explanation:
When a power of 10 is positive the dot must be moved to the right, and when the power of 10 is negative, the dot must be moved to the left.
For example  and
 and 
So

wich is clearly not equal to 0.000002015
the correct scientific notation for 0.000002015 must be:
 
 
With a negative in the power of 10, referring to a small quantity.
 
        
             
        
        
        
Answer:
B 110
Step-by-step explanation:
The formula for circumference is C= pi × d
(I couldn't find the symbol for pi)
You would plug in 35 for d to solve. You get a long decimal so you round it to 110. 
So the approximate circumference for the tabletop is 110 inches.
 
        
                    
             
        
        
        
ax^2 + bx+c =0
discriminant b^2-4ac
(-6)^2 - 4(1) *(9)
36-36 = 0
if the discriminant >0  it has 2 real roots
                               = 0  it has 1 root of multiplicity 2
                              < 0 has 2 imaginary root
x^2 - 6x + 9 = 0 
(x-3)(x-3)=0
root is 3 multiplicity 2
Answer : double root real and rational
 
        
             
        
        
        
Slope formula: y2-y1/x2-x1
Part one:
-7-4/-7-(-7)
-11/0
Since the denominator is 0, the slope is undefined.
Part two:
-9-(-9)/2-(-5)
0/7
Since the numerator is 0, the slope is 0.
Best of Luck!
