Answer: the slope should be -7/3
1.05 should be it
Step-by-step explanation:
In a recursive formula, each term of the sequence is found by using the previous term. In this case, the sequence is geometric because we are multiplying each term by the same constant, called a common ratio.
To find this common ratio, we find the percent of change between terms. We do this by using the formula
% change = (amount of change)/(original amount)
The amount of change between the first two terms is 105-100 = 5. This makes the percent change
5/100 = 0.05
The amount of change between the second two terms is 110.25-105 = 5.25. This makes the percent change
5.25/105 = 0.05
However, the common ratio in the sequence is not 0.05. This is because multiplying by this decimal would make the terms decrease instead of increasing. In this case, we are taking 100% of the number and adding an extra 5% (0.05 = 5%); this makes our common ratio 105% = 1.05.
This gives us the recursive formula
Answer: At least 32 calendars.
Step-by-step explanation:
Since they already have $350 out of the $600, they only need to raise $250 more (600-350).
Each calendar is $8
To find how many calendars are needed to raise $250, divide it by $8 (250/8=31.25)
Since you cannot sell .25 of a calendar it would round up to be 32.
If we plug 2 in for x we get
4^2 or 4 x 4
And
2^4 or 2 x 2 x 2 x 2
4 x 4 is 16 and 2 x 2 x 2 x 2 is also 16
So when x=2 the difference between the 2 expressions is 0
