Answer: D. 60100
Step-by-step explanation:
The formula for determining the sum of n terms of an arithmetic sequence is expressed as
Sn = n/2[2a + (n - 1)d]
Where
n represents the number of terms in the arithmetic sequence.
d represents the common difference of the terms in the arithmetic sequence.
a represents the first term of the arithmetic sequence.
From the information given,
n = 200 terms
a = 2
d = 3
Therefore, the sum of the first 200 terms, S200 would be
S200 = 200/2[2 × 2 + (200 - 1)3]
S200 = 100[4 + 597)
S200 = 100 × 601 = 60100

<h2>What is the rate of change of the line through (3, -5) and (-5, 3)?..........</h2>
Answer:
D
Step-by-step explanation:
I don't know how to eliminate the wrong answers.
Two line segments which have one end at a diameter and the other end meeting at a common point, make a 90 degree angle.
A is made that way, so A is 90 degrees.
Answer:
7/4 or 7 over 4
Step-by-step explanation:
slope formula: (y2 - y1) / (x2 - x1)
= (6 - (-8)) / (5 - (-3))
= (6 + 8) / (5 + 3)
= 14 / 8
=7 / 4
