Answer:
(A) -2018
(B) 5/36
Step-by-step explanation:
(A) The rate of change between any pair of terms in an arithmetic sequence is the same:
(a668 -a38)/(668 -38) = (a38 -a13)/(38 -13)
a668/630 = a38/630 +(a38 -a13)/25 . . . . add a38/630 to both sides
a668 = a38 +630/25(a38 -a13) = -128 +25.2(-128 -(-53)) = -128 -1890
a668 = -2018

(B) The sum of an infinite geometric series is ...
S = a1/(1 -r) . . . . . . for first term a1 and common ratio r
We are given S = 6, a1 = 5, so we can find r to be ...
6 = 5/(1 -r)
1 -r = 5/6
1 -5/6 = r = 1/6
Then the 3rd term is ...
a3 = 5×(1/6)^(3 -1) = 5/36
Answer:
20-5 × 5 + 3 × 6

Answer:
70%
Step-by-step explanation:
Out of 7+3 = 10 total hours Samuel logged on Thursday, 7 were spent with clients. The fraction of hours spent with clients was ...
client hours / total hours = 7/10
Multiplying by 100% converts that to a percentage:
Thursday client time = 7/10 × 100% = 70%
Answer:
4(3 * 39 – 12) = 5(2 * 39 + 6)
x = 39
Step-by-step explanation:
4(3x – 12) = 5(2x + 6)
(12x - 48) = (10x + 30)
12x - 10x = 30 + 48
2x = 78
2x/2 = x
78/2 = 39
x = 39
No Prob :)
