Answer:
p4 + p2 + p - k = 0
plug p=1 into the equation and find k
1^4 + 1^2 + 1 - k = 0
1 + 1 + 1 - k = 0
k = 3
B. I promise it’s b because I took the test

Answer:
Sum of the first five terms of the geometric sequence in which a1=5 and r=1/5 is
Step-by-step explanation:
We need to find sum of the first five terms of the geometric sequence in which a1=5 and r=1/5
The formula used to find sum of the geometric sequence is:
Where a is the first term, r is the common ratio and n is the number of terms
Now finding sum of the first five terms of the geometric sequence
We have a=5, r=1/5 and n=5
Putting values in the formula:
So, sum of the first five terms of the geometric sequence in which a1=5 and r=1/5 is
I think the answer is d. but I'm not really sure
