Answer:
Y(n) = 7n + 23
Step-by-step explanation:
Given:
f(0) = 30
f(n+1) = f(n) + 7
For n=0 : f(1) = f(0) + 7
For n=1 : f(2) = f(1) + 7
For n=2 : f(3) = f(2) + 7 and so on.
Hence the sequence is an arithmetic progression with common difference 7 and first term 30.
We have to find a general equation representing the terms of the sequence.
General term of an arithmetic progression is:
T(n) = a + (n-1)d
Here a = 30 and d = 7
Y(n) = 30 + 7(n-1) = 7n + 23
You should use the calculator and just plug in those numbers
Answer:
1) "fake numbers" do not exist but there are irrational numbers
2) We have negative numbers to help us understand the number system better. We need negative numbers in graphing.
260 because the tens position is the far right one before the decimal, and the number is above 5.
Multiple first to get 568.567
nearest cent would be the hundredths place which is a 6, look to the right, it's a 7 (rule 5 or more round up, 4 or less keep number) the 7 is above 5
so it becomes 568.57
