Answer:
 procedure always produces 6
Step-by-step explanation:
Let 'n' be the unknown number
Add 4 to the number : n+4
multiply the sum by 3. 
multiply the sum n+4 by 3

Now subtract 6, so we subtract 6 from 3n+12

finally decrease the difference by the tripe of the original number
triple of original number is 3n

so the procedure always produces 6
 
        
             
        
        
        
Answer:
-40x
Step-by-step explanation:
f(x) =-3x-5
g(x) =4x-2
(f+g)(x) =?
now,
 f(g(x))
 =f(4x-2)
 =-3×4x-2-5
 =-10×4x
 =-40x
 
        
             
        
        
        
11 times 3 would be one way and 1 times 33 would be the last way to get 33 as an answer ;)
        
             
        
        
        
So basically all you have to do is find the area of one of the smaller semi circles by using the formula for the area of a circle (A=πr^2). You know that the length of the larger semi circle's radius is equivalent to 6 cm because the radius of the smaller ones are 3 cm, meaning the diameter would have to be 6 cm and in this case, the length of the smaller semi circles' diameters is equal to the radius of the big semi circle. Then you would find the area of the big semi circle again by using the area of a circle formula, but after getting the answer you would half it, obviously because it's a semi circle. Subtract the are of the smaller semi circle you found earlier from the answer you just got and that's it ;) (you wouldn't have to half the area since there are two smaller semi circles and 1/2 + 1/2 = 1 but u knew that)
Put simply, the answer would be about 88.2644 cm because circles.
 
        
             
        
        
        
Answer:
They are at the same height at 1.13 seconds.
Step-by-step explanation:
Remark
The rockets are at the same height when  f(x) = g(x) [see below] are the same. So you can equate them.
Givens
f(x) = - 16x^2 + 74x + 9
g(x) = -16x^2 + 82x              I have changed this so you don't have 2 f(x)s
Solution
- f(x) = g(x)
- -16x^2 + 74x + 9 = -16x^2 + 82x                        Add:  16x^2 to both sides
- -16x^2+16x^2+74x + 9 = -16x^2+16x^2 + 82x   Combine terms
- 74x + 9 = 82x                                                     Subtract 74x from both sides
- 74x - 74x + 9 = 82x - 74x                                  Combine
- 9 = 8x                                                                 Divide by 8
- 9/8 = 8x/8
- x = 1 1/8                                                              Convert to decimal
- x = 1.125
- x = 1.13  [rounded]
