Answer:
To find out the first three terms of 3n - 2 substitute 1 ,2 and 3 into the equation. 
so the three terms a
  3(1)-2=1
 3(2)-2=6-2=4
 3(3)-2=9-2=7
 As you can see the sequence goes up in 1,4 and 7.To find out the 10th term you also substitute 10 into the equation so 3(9)-2=18-2=16
so 16 is the tenth term
 Hope this helped!
 
        
             
        
        
        
Let the speed of the joker initially be x mi/hr
after reduction, the new speed will be: (x-1) mi/hr
but
time=(distance)/(speed)
hence :
Total time taken will be:
4/x+5/(x+1)=41/20
solving for x we get:
x=21.585 mi/hr
thus the initial speed was 21.585 mi/hr after reduction the new speed was 20.585 mi/hr
        
             
        
        
        
Answer:
20.2 miles
Step-by-step explanation:
This can be described by the three sides of a right angled triangle. Let the distance of the glider to the airport be represented by x, applying the Pythagoras theorem:
 =
 =  +
 + 
 =
 =  +
 + 
576 =  + 169
 + 169
 = 576 - 169
 = 576 - 169
    = 407
x = 
   = 20.1742
x = 20.2 miles
The glider has to fly 20.2 miles to return to the airport.
 
        
             
        
        
        
Five-5
three-3
"the quantity five plus three" (5 + 3) 
"one hundred times the quantity ..." means  100 (5 + 3)   
now just solve 100(5+3) 
solve the parentheses first (5+3) = 8
Now you are left with 100(8) or 100*8
when you solve your answer is 800
        
             
        
        
        
Answer:
C complex
Step-by-step explanation:
 a+ bi
a is the real part and bi is the imaginary part
Together they make a complex number
