Hi, thank you for posting your question here at Brainly. Whatever the sequence is, the important thing is to follow the explicit rule. The n denoted in the equation must pertain to the 12th term. Hence,
A12 = -16 + 2(12)
A12 = 8
The 12th term is 8. I hope I was able to help. Have a good day.
Answer:
22 times
Step-by-step explanation:
Since there are four colors that cycle in each pattern stage (blue green yellow orange) and there are 88 beads, there would be 22 repetitions of the pattern since 88/4 = 22.
Answer:
see explanation
Step-by-step explanation:
Given
f(x) = x² - p(x + 1) - c
= x² - px - p - c ← in standard form
with a = 1, b = - p and c = - p - c
Given that α and β are the zeros of f(x), then
α + β = - and αβ = , thus
α + β = - = p , and
αβ = = - p - c
-----------------------------------------------------------
(α + 1)(β + 1) ← expand factors
= αβ +α + β + 1 ← substitute values from above
= - p - c + p + 1
= - c + 1 = 1 - c ← as required
Answer:
d + n = 22 and 0.1d + 0.05n = 1.9
Step-by-step explanation:
Let d represents the number of dimes and n represents the number of nickel.
Total of dimes and nickels = 22
Therefore, d + n = 22
1 dime = 10 cents = 0.1
1 nickel = 5 cents = 0.05
Value of 22 dimes and nickel = $1.90
So, 0.1d + 0.05n = 1.9
Hence, d + n = 22 and 0.1d + 0.05n = 1.9 models the given situation.
