Answer:
Step-by-step explanation:
Use FOIL method
(x + 6)(x +6) = x*x + x*6 +6*x + 6*6
= x² +<u> 6x + 6x</u> + 36 {add like terms}
= x² + 12x + 36
Answer:
20%
Step-by-step explanation:
Given that
The car is depreciated at a rate of 7% per year
We need to find out the percentage when the car is depreciated after 6 years
So,
Since the car is depreciated by 7% so we can say it can be 0.93 times in a year
Now after 6 years, it would make
= 0.93^3
= 0.80
So, the percentage is
= 1 - 0.80
= 0.20
= 20%
We know that the number of users triple each day
Let number of users on day 1 be x
⇒ Users on day 2 =
= 3x
and Users on day 3 =
= 9x
And so on...
% Increase in users from day 1 to day 2 = 
⇒ % Increase in users from day 1 to day 2 = 
⇒ % Increase in users from day 1 to day 2 = 
⇒ % Increase in users from day 1 to day 2 = 200%
Similarly,
% Increase in users from day 2 to day 3 = 
⇒ % Increase in users from day 2 to day 3 = 
⇒ % Increase in users from day 2 to day 3 = 
⇒ % Increase in users from day 2 to day 3 = 200%
Hence, we can see that the percentage increase each day is 200%
Parallel lines have the same slope. The equation of the parallel line is therefore:
y = x + b
Plug in the values you are given to find b:
2 = -3 + b
b = 5
I would go with A. The exact answer is 1/11
