What is the explicit formula that represents the following sequence? {1,-6,36,-216...} A5
2 answers:
N=#
-6(n)
I think this is the answer
We see this a geometric sequcne because each term is -6 times of the previous term
an=a1(r)^(n-1)
an=nth term
a1=first term
r=common ratio
n=which term
we see that it multiplies by -6 each time
and the first term is 1
so r=-6
a1=1
an=1(-6)^(n-1)
the explicit formula is
and a5=1(-6)^(5-1)=1(-6)^4=1296

Answer:
Step-by-step explanation:
- (18u^2 - 142u - 11) ÷ (u - 8)
- 18u^2 - 142u - 11 =
- 18u^2 - 8*18u + 2u - 11 =
- 18u(u - 8) + 2u - 16 + 5 =
- 18u(u - 8) + 2(u - 8) + 5 =
- (18u + 2)(u - 8) + 5
- (18u^2 - 142u - 11) ÷ (u - 8) = 18u + 2 + 5/(u - 8)
The answer to the question is 43
Answer:
$26.91
Step-by-step explanation:
9.50 +13.93 =23.43
50.34 - 23.43 = 26.91
You want to solve for x so add 18 from both sides of the equal sign. making it 3x=12. then divide both sides by 3 making x=4. x is 4.
0.25 times r added to 0.6 times 6
