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
Answer:
$18
Step-by-step explanation:
It is 10% off so you are paying 90% of $20.
20*0.9=18
The 10% is $2
Answer: 3 is the answer
Step-by-step explanation:
To get the graph to have one x-intercept, we must find the m value where the discriminant of the equation will equal 0.
The discriminant for a graph with one x-intercept is found with the following formula:

Plug in the values of the equation into this formula:



Add 144 to both sides:

Square root both sides to get m by itself:


In order for the graph to have one x-intercept, m must equal
-12 or 12.
