Answer:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Exact Form:
x=1+√5 ,1−√5
The geometric sequence can be represented explicitly or as recursions
The explicit formula of the geometric sequence is b(n) = 2 * 3^(n-1)
<h3>How to determine the explicit formula?</h3>
The sequence is given as:
2, 6, 18, 54, ....
Start by calculating the common ratio (r)
r = b2/b1
This gives
r = 6/2
Evaluate the quotient
r = 3
A geometric sequence is represented as:
b(n) = b1 * r^(n-1)
This gives
b(n) = 2 * 3^(n-1)
Hence, the explicit formula of the geometric sequence is b(n) = 2 * 3^(n-1)

Answer:
D. (2.4, -1).
Step-by-step explanation:
The midpoint of the line segment with endpoints (x1,y1) and (x2,y2) is
[(x1+x2) / 2 , (y1+y1)/2 ].
So here we have : [ (3.2+1.6)/ 2 (2.5 - 4.5)/2)
= (2.4, -1) answer.
Answer: 30
Step-by-step explanation:
Let x stand for the measure of angle 1. Then. 2x for angle 2 and finally 3 x for angle 3.
So, x + 2x + 3x = 180
and 6x = 180
Therefore, x = 30, 2x = 60 and 3x = 90.
Answer:
