Answer:
I think that the answer is A
Step-by-step explanation:
Answer:
step 3: he should have divided both sides by -7
A. let the distance be d
so we have Δd/Δt=8.8min
Δd= 8.8Δt
d=∫8.8Δt-------(1)
b. d should be positive because the diver is ascending at a positive rate relative to depth
c. d=rt
t=d/r = 32.12/8.8 min
t= 3.65min
From the recursive rule

it follows that


and so on. Notice how the subscript on a on the right side and the coefficient multiplied by 13 add up to n (n - 2 + 2 = n; n - 3 + 3 = n; and so on). If we continue the pattern, we'll end up with

so that the explicit rule for the n-th term in the sequence is

Hello :
2x²+3x+1=0
a=2 b=3 c=1
b²-4ac = (3)²-4(2)(1) = 1
