Answer:
The sum of the first 51 terms of the sequence is 6018
Step-by-step explanation:
AP: −282,−266,−250,−234,...
First term = a = -282
Common difference = d = 
Common difference = d = -266-(-282)=-250-(-266)=16
Formula of sum of first n terms =
Substitute n = 51
So,

Hence the sum of the first 51 terms of the sequence is 6018
Answer:
B is correct i think
Step-by-step explanation:
Answer:
Range : [-6, ∞)
Step-by-step explanation:
Domain of any function on a graph is represented by the x-values (input values).
Similarly, Range of function is represented by the y-values or output values of the function on a graph.
Therefore, domain of the given absolute function will be (-∞, ∞) Or set of all real numbers.
Range of the function → [-6, ∞) Or {y | y ≥ -6}

<u>Answer:</u>
29 years
<u>Step-by-step explanation:</u>
- Given the function
, where x stands for the number of years since the material was put into the vault, we can plug 140 into x to find the amount leftover. - Another way of doing this is to change the function to
which are equivalent functions, and then plug 140 into x. This function is helpful if you also needed to find the rate. - I'll use the 1st function because the question doesn't ask for the rate

From here I'll just use a calculator & get 28.7, or 29 years.
