O A. – 16x4
O B. -8x4
O C. -2xt
O D. 84
O E. 16x4
Answer:
The answer should be -8x
Step-by-step explanation:
You would use distiputive property and multiple four by negitive two and you would end up getting -8x
an = one third(27)n − 1
an = 27(one third)n − 1
an = one third(3)n − 1
an = 3(one half)n − 1
Answer:
C is correct.
Step-by-step explanation:
We need to choose correct model by the graph which passes through the points (2,1) (3,3) and (4,9)
Option 1:
Put n=2 and to get a₂=1
False
Option 2:
Put n=2 and to get a₂=1
False
Option 3:
Put n=2 and to get a₂=1
TRUE
Similarly, we will check (3,3) and (4,9)
and we will get true
Hence, The sequence is
Answer:
the answer is C. an = one third (3)n − 1

224 flowers 324 flowers
56 seed packets (324*56)/224=81 seed packets
Answer:
7 nickles
8 dimes
4 quarters
Step-by-step explanation:
q
d = 2q
n = q+3
25q + 10d + 5n = 215
25q + 10(2q) + 5(q + 3) = 215
25q + 20q + 5q - 15 = 215
50q = 200
q = 4
d = 2q = 8
n = q + 3 = 7
Answer:15 seniors served on the student council during their freshman year, 14 seniors served during their sophomore year, 16 seniors served during their junior year, and 3 seniors have never served before.
Step-by-step explanation:
Using inclusion and exclusion principles, we find that 2 seniors served on the student council during each of the four years in high school.
The problem can be solved using the Principle of Inclusion and Exclusion (PIE), a common technique in combinatorial mathematics. First, we add the number of seniors serving in their freshman, sophomore, and junior years: 3 (never served) + 10 (junior) + 9 (sophomore) + 11 (freshman) giving us 33.
Then, we subtract the number of seniors who served during both sophomore and junior years, freshman and junior years, and freshman and sophomore years: 33 - 5 (sophomore and junior) - 6 (freshman and junior) - 4 (freshman and sophomore). This results in 18.
However, from the initial condition we know that there are 20 seniors in total. Therefore, the two 'extra' seniors must have served all four years in high school. Thus we find that 2 seniors served on the student council during each of the four years in high school.
