Answer:
A Series is always a periodic sum of terms, so only A and D will apply to that definition
(where A= 1/2 + 1/4 + 1/6 + 1/16 + 3.14159 and B=25 - 5 - 10 - 15 - - 125
I hope this helps you
s' (t)=0-4
s' (t)=-4
t=8
s' (8)=-4
Answer:
You could try to do it side by side then the area x side.

Sorry if it is not much help, hope you figure it out!
Answer:
C,20%
Step-by-step explanation:
First we are told that she has 3 hours to grade 35 student papers ,and she has 30 minutes to grade 5 paper, now we calculate how long it took her to grade 1 paper.
Part1
if 5papers = 30minutes
therefore 1paper = (30*1)/5 = 6mins per paper.
now we are left with 2hrs 30mins(150 mins) to grade 30papers
Part2
if 30papers = 150minutes
therefore 1paper = (150*1)/30 = 5mins per paper.
to calculate how fast she has to be in relation to the first part
we substract :
(6mins- 5mins)/ 5mins *100 =1/5 * 100 = 20%.
The first term and common ratio for the geometric sequence are -3 and 5 respectively
<h3>Geometric sequence</h3>
This are sequence that increases exponentially. The nth term of the sequence is given as:
Tn = ar^n-1
where;
a is the first term
r is the common ratio
n is the number of terms
ar = -15
ar^3 = -375
Divide
r^2 = 375/15
r^2 = 25
r = 5
Determine the first term
a= -15/r
a = -15/5
a = -3
Hence the first term and common ratio for the geometric sequence are -3 and 5 respectively
