Answer:
13.2 ft
Step-by-step explanation:
x^2 + 8.2^2 = 15.5^2
x = 13.2 ft
well, the recursive rule of aₙ = aₙ₊₁ + 7, where a₁ = 15, is simply saying that
we start of at 15, and the next term is obtained by simply adding 7, and so on.
well, that's the recursive rule.
so then let's use that common difference and first term for the explicit rule.
<h2>Explanation:</h2><h2 />
When we say "a is at most b" we mean that "a is less than or equal to b" or "a is not greater than b". So let's solve this problem as follows:
Step 1. Twice the difference of a number and 2
Let's call that unknown number as n. Then, twice the difference of a number and 2 is:
Step 2. Twice the difference of a number and 2 is at most -27
_________________________________________
So the mathematical form of the statement <em>twice the difference of a number and 2 is at most -27 </em>is:
