1 question I believe it’s A. 2 question I believe it’s C. 3 question I believe it’s B. Hope this help❤️.
Umm what do you mean can you explain more of it 2 me plz<span />
The correct answer is maybe 3
The point-slope form:
- given point
- given slope
The standard form:
<em>use distributive property</em>
<em>add 
to both sides</em>
<em>subtract 
from both sides</em>
<em>change the signs</em>
Answer:
The first term of the geometric series is 1
Step-by-step explanation:
In this question, we are tasked with calculating the first term of a geometric series, given the common ratio, and the sum of the first 8 terms.
Mathematically, the sum of terms in a geometric series can be calculated as;
S = a(r^n-1)/( r-1)
where a is the first term that we are looking for
r is the common ratio which is 3 according to the question
n is the number of terms which is 8
S is the sum of the number of terms which is 3280 according to the question
Plugging these values, we have
3280 = a(3^8 -1)/(3-1)
3280 = a( 6561-1)/2
3280 = a(6560)/2
3280 = 3280a
a = 3280/3280
a = 1
