Answer:
an = -6*(1/4)^(n-1)
Step-by-step explanation:
We have that the recursive formula for the given geometric sequence is:
a1 = -6
an = (an-1) * (1/4)
With the above we can assume that:
r = 1/4
following the rule of the explicit formula that is given by:
an = a1 * (r) ^ (n-1)
we substitute and we have:
an = -6 * (1/4) ^ (n-1)
Therefore the explicit formula from the given data would be:
an = -6 * (1/4) ^ (n-1)
Answer:
approx 15.5 hours
Step-by-step explanation:
475/30 = 15.83 miles per hour
245 = 15.83·t
t = 245/15.83
t = 15.5 hours
Answer:
x ≥ 4
Step-by-step explanation:
Given
- 4(8 - 3x) ≥ 6x - 8 ← distribute parenthesis on left side
- 32 + 12x ≥ 6x - 8 ( subtract 6x from both sides )
- 32 + 6x ≥ - 8 ( add 32 to both sides )
6x ≥ 24 ( divide both sides by 6 )
x ≥ 4
