Part A :
D = (1/4) * C D = 1/4 * 24 D = 24/4 = 6 ft above sea level
Part B :
Your answer is positive because D is still above sea level...if it would have been below sea level, then it would have been negative
Answer: 1.6464
Step-by-step explanation: I think.
20 because it is counting by fives (5,10,15,20) and 5x4=20
The 50th term in the sequence is 199
Arithmetic sequence
The nth term of an arithmetic sequence is expressed as:
Tn = a+ (n - 1)d
where:
- a is the first term
- n is the number of terms
- d is the common difference
The sequence formed by the amount of Whatchamacallits produced as;
3, 7, 11, 15...
a = 3
d = 11-7 = 7-3 = 4
Substitute
Tn = 3 + (n-1) * 4
Tn = 3 + 4n -4
Tn = 4n - 1
Hence the explicit formula that models the production for the nth term of the sequence is Tn = 4n - 1
If n = 50
T50 = 4(50) - 1
T50 = 199
Hence the 50th term in the sequence is 199
