the formula for circumference is
In this case we are using 3.14 for pi and the radius is 6.4
Answer: Area=36
Step-by-step explanation:
Answer:
The first term is 3 and common difference is 8.
And
The formula for sequence is:
Function is:
Step-by-step explanation:
Given that
The general formula for arithmetic sequence is:
Here
a is the first term
n is the term number
and d is the common difference
for 4th term
For 8th term
subtracting equation 1 from equation 2
Putting d = 8 in equation 1
Now for the function
The sequence can also be expressed as a function as:
Hence,
The first term is 3 and common difference is 8.
And
The formula for sequence is:
Function is:
The answer is A because it can be put into the equation: y= 3x+10
