Answer : 14
Here is my step by step : Try to Always follow the PEDMAS
6 + 2 = 8
8-12 = - 4
1 . (-4) = 1 . 4 = - 4
= 4. 2
( - 4 ) . 2 = - 4 . 2 = 8
14 - 8 - ( - 8 )
14 - 8 = 6
6-(-8)
- (-8) = + 8
6+8 = 14
Hope that helped
Answer:
You can only add like terms with like terms, so the terms that can be combined with 3a are the terms that end in an a.
So, the answers are:
4a and 14a
Let me know if this helps!
False.
An exponential growth is a function of the form:
y = A (b) ^ (k * t)
Where,
k> 0
b> 1
Because the value of b> 1 means that the function grows.
Therefore, the answer to the question is false, because if k = 2 but b <1 then the function decreases.
Answer:
False
Answer:
364/27
Step-by-step explanation:
9, 3, 1, ... is a geometric sequence with common ratio r = 1/3.
The nth term is a1rn-1.
If a1rn-1 = 1/27, then 9(1/3)n-1 = 1/27
32(3-1)n-1 = 3-3
3231-n = 3-3
33-n = 3-3
3-n = -3
n = 6
The sum, Sn, of the first n terms of a geometric sequence is given by Sn = a1(1 - rn) / (1 - r).
So, 9 + 3 + 1 + ... + 1/27 = S6 = 9(1 - (1/3)6) / (1 - 1/3)
= 9(1 - 1/729) / (2/3)
= (27/2)(728/729) = 364/27
Number 6 would be
because all of the other numbers are irrational numbers
