Answer: 10
Step-by-step explanation: In this problem, we're asked to find the distance between the points (-1,2) and (7,8) so we use the distance formula which states that the distance between two points is equal to
.
Our first point, (-1,2) represents (, ) and our second point,
(7,8) represents (, ).
So, plugging the given information into the formula, we have.
Next, we simplify inside the parentheses to get.
Next, 8² is 64 and 6² is 36 so we have or which is 10.
So the distance between the points (-1,2) and (7,8) is 10.

Answer:
aₙ = - 30n + 9
Step-by-step explanation:
You can tell this is an arithmetic sequence, as there is a difference of 30 between each value. Therefore the equation we will use here is aₙ = a₁ + (n - 1)d.
aₙ = a₁ + (n - 1)d
= - 21 + (n - 1) * - 30
= - 21 - 30n + 30
= - 30n + 9
Your solution would be option d. aₙ = - 30n + 9
