0=40-10t-5t^2
t^2+2t-8=0
(t+4)(t-2)=0
t=-4 (not a solution) or t=2

Answer:
7.1 miles
Step-by-step explanation:
From the park to the library is a diagonal line. We can use pythagorean theorem.
Change in y - 7
Change in x - 1
7^2 + 1^2 = x^2
(x is the distance between the library and park)
49 + 1 = x^2
50 = x^2
That's around 7.
Answer:
A recursive formula designates the starting term, a1, and the nth term of the sequence, an , as an expression containing the previous term (the term before it), an-1.Find a recursive formula. This example is an arithmetic sequence (the same number, 5, is added to each term to get to the next term).
