Answer:
Step-by-step explanation:
80,120,160.....
This is an arithmetic sequence
common difference (d) = 2nd term - 1st term
= 120 - 80 = 40
first term (a) = 80
nth term = a + (n-1)d
= 80 + (n-1)*40
= 80 + 40n -40
= 40 + 40n
Answer:
k = 26
Step-by-step explanation:
90 + 8 = x + k
x = 72
90 + 8 = 72 + k
90 + 8 = 98
98 = 72 + k
98 = 72 + k
-72 -72
98 - 72 = 26
72 + k - 72 = k
26 = k
k = 26
Answer: 12
Step-by-step explanation:
1. x-5
2. 12x + 5
3. x/5
4. 3x - (x + 5)
hope i helped :)
we know that
The exponential function is of the form

where
a is any value greater than 
In General:
It is always greater than
, and never crosses the x-axis
It always intersects the y-axis at 
Its Domain is the Real Numbers
Its Range is the Positive Real Numbers
Examples
Let

1) For 

2) For 

3) For 

4) For 




therefore
the answer is the option
D.) exponential
