Answer:
3225
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
= 
[ 2a + (n - 1)d ]
where a is the first term and d the common difference
here a = 6 and
d = 13 - 6 = 20 - 13 = 7, hence
= 
[ (2 × 6) + (29 × 7) ]
= 15(12 + 203) = 15 × 215 = 3225
It's a mixed fraction so it would be 1 2/10 and 1 4/100
A discontinuity is present if any of ...
- the limit doesn't exist
- the limit is not the same as the value of the function
If the one of these that is the cause of discontinuity is the last one and defining the function will make this issue go away, then the discontinuity is removable.
Let's say is "x", so, then "x" is the 100%, and we know that the 60% is 120, what the dickens is "x" anyway?
Answer:
y = x² + 3x - 40
Step-by-step explanation:
Given the zeros are x = - 8 and x = 5, then the factors are
(x + 8) and (x - 5) and
y = (x + 8)(x - 5) ← expand factors
y = x² - 5x + 8x - 40, hence
y = x² + 3x - 40 ← in standard form
